Researchers at the Department of Physics at the University of Houston and Texas Center for Superconductivity have received a second-year funding from global leader in business of invention Intellectual Ventures to continue their work on exploring superconductivity,

The project, which is led by Paul C. W. Chu, T.L.L. Temple Chair of Science, professor of physics and founding director of the TcSUH and assistant professor of physics and a new TcSUH principal investigator Liangzi Deng, has been awarded $767,000 to date.

“Working with IV gives us the freedom known for scientific pursuit and at the same time provides intellectual guidance and assistance in accord with the mission goal,” Chu says in a news release.

The researchers are working on making superconductivity easier to achieve. At room temperature and normal atmospheric pressure is where the researchers are looking to simplify superconductivity. One finding from Chu and Deng’s team is called pressure-quench protocol, or PQP.The PQP will help maintain key properties (like superconductivity) in certain materials after the high pressure needed to create them is removed.

“Intellectual Ventures funded this research because Paul Chu is one of the acknowledged thought leaders in the area of superconductivity with a multi-decade track record of scientific innovation and creativity,” Brian Holloway, vice president of IV’s Deep Science Fund and Enterprise Science Fund, adds. “The work led by Chu and Deng on pressure quenching could result in game-changing progress in the field. We are very excited about the preliminary results from the first year and we look forward to continuing this collaboration.”

The project showed early success the first year, as the research used a special system to synthesize materials under high temperatures and pressure. The second-year projects will include the investigation of pressure-induced/enhanced superconductivity in cuprates and hydrides.

“If successful, UH will once again break the record for the highest superconducting Tc at atmospheric pressure,” Deng says in the release. “Additionally, we will collaborate closely with theorists to uncover the mechanism of PQP. Our research has far-reaching implications, with the potential to extend beyond superconductors to other material systems.”

A View From HETI

A new 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.
