An international team of researchers has published a strategy paper in the Proceedings of the National Academy of Sciences outlining a systematic approach to finding materials that can conduct electricity at room temperature without losing energy. The team, which includes Christoph Heil from Graz University of Technology, says there are no fundamental physical laws that rule out superconductivity at ambient temperature. They propose two key challenges: improving computer models to better predict producible superconducting materials, and purposefully manipulating materials using techniques like extreme pressure, doping, and nanostructures to generate or amplify superconducting states. The researchers call for a coordinated global effort to link theory, simulation, and experiment to push the limits of superconductivity towards room temperature.

Why it matters

The discovery of room-temperature superconductors could revolutionize numerous areas of technology and everyday life, enabling loss-free power transmission, more efficient motors and generators, more powerful quantum computers, and cheaper MRI devices. This is one of the greatest challenges in modern physics, with the potential to change many industries at once.

The details

The researchers point to recent progress as evidence that superconductivity is not a rare phenomenon, but an almost universal property of non-magnetic metals under the right conditions. They highlight a new record set by researchers at the University of Houston, who used a process called pressure quenching to raise the critical temperature of a mercury-based compound from 133 Kelvin to up to 151 Kelvin at ambient pressure. To build on these advances, the team has identified two key tasks: improving computer models to better predict producible superconducting materials, and purposefully manipulating materials using techniques like extreme pressure, doping, and nanostructures to generate or amplify superconducting states. They propose treating potential superconductors as "quantum metamaterials" where the superconducting properties are determined by precisely designed nanoscale structures, not just chemical composition.

  • In 1993, the mercury-based compound Hg-1223 set the record for superconductivity at normal pressure.
  • In the recent study, researchers at the University of Houston used pressure quenching to raise the critical temperature of Hg-1223 to up to 151 Kelvin.

What they’re saying

“In recent years, we have made enormous progress in the computer-aided simulation of realistic materials. Today, we can carry out ab-initio calculations on superconductivity in the nanometre range – in other words, on length scales that are actually accessible in experiments. Just a few years ago, we were limited to much smaller unit cells in the angstrom range – that's a difference of around a power of ten.”

What’s next

The researchers call for a coordinated global effort to link theory, simulation, and experiment to systematically search for room-temperature superconductors.

The takeaway

By combining advanced computer modeling, machine learning, and targeted material manipulation, the research community hopes to make a major breakthrough in the decades-long quest for room-temperature superconductors, which could revolutionize numerous industries.
