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.

Houston-based Syzygy Plasmonics has announced a partnership with Velocys, another Houston company, on its first-of-its-kind sustainable aviation fuel (SAF) production project in Uruguay.

Velocys was selected to provide Fischer-Tropsch technology for the project. Fischer-Tropsch technology converts synthesis gas into liquid hydrocarbons, which is key for producing synthetic fuels like SAF.

Syzygy estimates that the project, known as NovaSAF 1, will produce over 350,000 gallons of SAF annually. It is backed by Uruguay’s largest dairy and agri-energy operations, Estancias del Lago, with permitting and equipment sourcing ongoing. Syzygy hopes to start operations by 2027.

"This project proves that profitable SAF production doesn't have to wait on future infrastructure," Trevor Best, CEO of Syzygy Plasmonics, said in a news release. "With Velocys, we're bringing in a complete, modular solution that drives down overall production costs and is ready to scale. Uruguay is only the start."

The NovaSAF 1 facility will convert dairy waste and biogas into drop-in jet fuel using renewable electricity and waste gas via its light-driven GHG e-Reforming technology. The facility is expected to produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel.

Syzygy will use Velocys’ microFTL technology to convert syngas into high-yield jet fuel. Velocys’ microFTL will help maximize fuel output, which will assist in driving down the cost required to produce synthetic fuel.

"We're proud to bring our FT technology into a project that's changing the game," Matthew Viergutz, CEO of Velocys, added in the release. "This is what innovation looks like—fast, flexible, and focused on making SAF production affordable."
