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.

Houston museum showcases America's founding documents in rare exhibit

Experience History

As the United States prepares to celebrate its 250th birthday, Houstonians have a chance to see rare documents from the founding of the nation. Freedom Plane National Tour: Documents That Forged a Nation, presented by the National Archives Foundation, will be on display at the Houston Museum of Natural Science through Monday, May 25.

The collection includes a rare engraving of the original Declaration of Independence; official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton; a draft of the Bill of Rights; the Treaty of Paris, the documented that recognized America's independence from Great Britain; and the tally of votes approving the Constitution.

The National Archives specifically chose Houston as one of only eight cities in the country to host the exhibit as a means to help the documents reach a wider audience outside of the main hub of semiquincentennial events in New England and the Washington, D.C. area.

"One of the things we decided when we put the tour together because we wanted to be off the East Coast," said Patrick Madden, CEO of the National Archives Foundation, who was onsite for the exhibit's opening in Houston. "There's a lot of 250th celebration stuff happening in the original 13 colonies. How do we get it to major markets where larger numbers of people can see it? So in the case of Houston, obviously, [is a] major market in this part of the country, but also we've partnered with the museum twice before with National Archives exhibits, so we knew that they would be up to the task of handling the exhibit and the crowds."

The star of the collection is a rare engraving of the original Declaration of Independence. Secretary of State and future president John Quincy Adams commissioned 200 exact replicas of the document from engraver William J. Stone in 1823. Less than 50 now remain. Madden joyfully pointed out that there are errors in this document, a potent reminder that the men who forged a nation made mistakes.

"There's a couple of typos in it where they had to make corrections," said Madden. "So even the founders, you know, they're all human. That resonates because here these people are making this move against the most powerful nation in the world and putting their lives on the line for a country based on ideas."

Other impressive parts of the collection include official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton, as well as one of the drafts of the Bill of Rights. Many states would not ratify the Constitution until certain rights were included in the document, leading to Washington going on a national tour assuring state leaders enshrining protections was first on the list. The draft copy on display specifically shows the First Amendment in progress.

Houston is the fourth stop on the exhibition's tour, which will take the documents to Denver, Miami, Dearborn, and Seattle through the summer. Freedom Plane is just one part of a larger patriotic celebration at the HMNS, which includes a film series celebrating American science and culture and general Americana decoration throughout the main hall.

Admission to Freedom Plane is free to the public, but separate from general admission to the museum. Space is limited, and passes are available on a first-come, first-serve basis. Non-members should expect long waits or the possibility that the day's passes are sold out. Only museum members can reserve passes for specific times. Flash photography is prohibited due to the fragile nature of the documents.

Houston quantum energy chip startup emerges from stealth with $12M round

seed funding

Houston-based Casimir has emerged from stealth with a $12 million seed round to commercialize its quantum energy chip.

The round was led by Austin-based Scout Ventures. Lavrock Ventures, Cottonwood Technology, Capital Factory, American Deep Tech, and Tim Draper of Draper Associates also participated in the round. The oversubscribed round exceeded the company’s original $8 million target, according to a news release.

Casimir’s semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company plans to commercialize its first-generation MicroSparc chip by 2028.

The MicroSparc chip measures 5 millimeters by 5 millimeters and is designed to produce 1.5 volts at 25 microamps, comparable to a small rechargeable battery, without degradation and no replacement cycle.

“Casimir represents exactly the kind of breakthrough dual-use technology Scout Ventures was built to back,” Brad Harrison, founder and managing partner at Scout Ventures, said in the release. “This is based on 100 years of science and we’re finally approaching a commercial product … We’re proud to lead this round and support Casimir’s journey from applied science to deployed technology.”

Casimir says it aims to scale its technology across the ”full power spectrum,” including large-scale energy systems that can power homes, commercial infrastructures and electric vehicles.

Casimir's scientific work has been supported by DARPA-funded nanofabrication research and its technology was incubated at the Limitless Space Institute (LSI). LSI is a nonprofit that works to innovate interstellar travel and was founded by Kam Ghaffarian. Technology investor and serial entrepreneur Ghaffarian has been behind companies like X-energy, Intuitive Machines, Axiom Space and Quantum Space.

Harold “Sonny” White, founder and CEO of Casimir, believes the technology can power devices for years without replacements.

“Millions of devices will operate for years without a battery ever needing to be replaced or recharged because we have engineered a customized Casimir cavity into hardware capable of producing persistent electrical power,” White added in the release. “I spent nearly two decades at NASA studying how we power humanity’s future. That work led me to the Casimir effect and the quantum vacuum, where new tools have allowed us to build on a century of scientific knowledge and bring abundant power to the world.”
