A study from researchers at Rice University, published in Nature Communications, could lead to future advances in superconductors with the potential to transform energy use.

The study revealed that electrons in strange metals, which exhibit unusual resistance to electricity and behave strangely at low temperatures, become more entangled at a specific tipping point, shedding new light on these materials.

A team led by Rice’s Qimiao Si, the Harry C. and Olga K. Wiess Professor of Physics and Astronomy, used quantum Fisher information (QFI), a concept from quantum metrology, to measure how electron interactions evolve under extreme conditions. The research team also included Rice’s Yuan Fang, Yiming Wang, Mounica Mahankali and Lei Chen along with Haoyu Hu of the Donostia International Physics Center and Silke Paschen of the Vienna University of Technology. Their work showed that the quantum phenomenon of electron entanglement peaks at a quantum critical point, which is the transition between two states of matter.

“Our findings reveal that strange metals exhibit a unique entanglement pattern, which offers a new lens to understand their exotic behavior,” Si said in a news release. “By leveraging quantum information theory, we are uncovering deep quantum correlations that were previously inaccessible.”

The researchers examined a theoretical framework known as the Kondo lattice, which explains how magnetic moments interact with surrounding electrons. At a critical transition point, these interactions intensify to the extent that the quasiparticles—key to understanding electrical behavior—disappear. Using QFI, the team traced this loss of quasiparticles to the growing entanglement of electron spins, which peaks precisely at the quantum critical point.

In terms of future use, the materials share a close connection with high-temperature superconductors, which have the potential to transmit electricity without energy loss, according to the researchers. By unblocking their properties, researchers believe this could revolutionize power grids and make energy transmission more efficient.

The team also found that quantum information tools can be applied to other “exotic materials” and quantum technologies.

“By integrating quantum information science with condensed matter physics, we are pivoting in a new direction in materials research,” Si said in the release.

Rice University inks strategic partnership with French research institution

collaboration station

Rice University and Université Paris Sciences & Lettres signed a strategic partnership agreement last week that states that the two institutions will work together on research on some of today's most pressing subject matters.

According to an announcement made on May 13 in Paris, the two schools and research hubs will collaborate on work focused on "fields of energy and climate; quantum computing and artificial intelligence; global health and medicine; and urban futures."

The partnership allows Rice to expand its presence in France, after launching its Rice Global Paris Center about two years ago.

Université PSL consists of 11 top research institutes in France and 2,900 world-class researchers and 140 research laboratories.

“We are honored and excited to partner with Paris Sciences and Lettres University and join forces to advance bold innovation and find solutions to the biggest global challenges of our time,” Rice President Reginald DesRoches said in a statement. “The unique strengths and ambitions of our faculty, students, scholarship and research are what brings us together, and our passion and hope to build a better future for all is what will drive our partnership agenda. Representing two distinct geographic, economic and cultural regions known for ingenuity and excellence, Rice and PSL’s efforts will know no bounds.”

Rice and Université PSL plan to host conferences around the four research priorities of the partnership. The first took place last week at the Rice Global Paris Center. The universities will also biannually select joint research projects to support financially.

“This is a global and cross-disciplinary partnership that will benefit from both a bottom-up, research-driven dynamic and a top-down commitment at the highest level,” PSL President Alain Fuchs said in a statement. “The quality and complementarity of the researchers from PSL and Rice who mobilized for this event give us reason to believe that this partnership will get off to a rapid and productive start. It will offer a strong framework to all the PSL schools for developing collaborations within their areas of strength and their natural partners at Rice.”

Rice launched its Rice Global Paris Center in June 2022 in a historic 16th-century building in Le Marais. At the time it, the university shared that it was intended to support Rice-organized student programs, independent researchers, and international conferences, as well as a satellite and hub for other European research activity.

"Rice University's new home in the Marais has gone from an idea to a mature relative with a robust program of faculty research summits, student opportunities, cultural events and community engagement activities," Caroline Levander, Rice's global Vice President, said at the announcement of the partnership last week.

Houston professor earns Google Scholar award for quantum computing research

recent recognition

A Rice University quantum computer scientist was one of 78 global professors to be presented with a 2023 Google Scholar award, the university announced this month.

Nai-Hui Chia, an assistant professor of computer science at Rice, was recognized for his research on Hamiltonian simulations, a method for representing the motion of moving particles. Chia aims to understand if quantum computers or machines can simulate a "Hamiltonian matrix" with a shorter evolution time.

"We call this fast-forwarding for a Hamiltonian simulation,” Chia says in a statement.

Chia aims to use the funds from Google to discover Hamiltonians that can be fast-forwarded using parallelism or classical computation, according to Rice. He will present his current work on Hamiltonians and their connection to cryptology in July at the 2023 Computational Complexity Conference in Warwick, UK.

The Google Research Scholar program grants funds of up to $60,000 to support professors' research around the world. This year's cohort works in fields ranging from algorithms and optimization to natural language processing to health research.

Three other Texas researchers were awarded funds in the 2023 cohort.

The University of Texas at Austin's Jon Tamir was awarded for his work in applied sciences. Atlas Wang, also from UT, was awarded in the machine learning and data mining category. Shenglong Xu, from Texas A&M University, joined Chia in the quantum computing category.

Tech behemoth Google has awarded funds to several Houston innovators in recent years.

Last summer the company named AnswerBite, Boxes and Ease to its inaugural cohort of the Google for Startups Latino Founders Fund. Selected companies received an equity-free $100,000 investment, as well as programming and support from Google.

In September 2022, ChurchSpace and Enrichly were named part of the Google for Startups Black Founders Fund. The companies also received $100,000 non-dilutive awards along with mentoring and support.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
