China's Synergetic Extreme Condition User Facility is opening its doors to more foreign scientists as it seeks to boost global collaboration in fundamental science and expand international experiment time at the site in Beijing over the next five years, experts said.

What astonishing phenomena might materials reveal when they are subjected to conditions mimicking the extremes of the cosmos-ultra-low temperatures, magnetic fields that are hundreds of thousands of times stronger than Earth's, and pressure close to that at the planet's core? The Synergetic Extreme Condition User Facility (SECUF), located in Beijing's suburban Huairou District, is opening a portal for scientists to observe the bizarre phenomena of matter under such extreme environments.

Researchers have discovered a chromium-based kagome metal, exhibiting strong electron correlations, frustrated magnetism, and characteristic flat bands near the Fermi level. The unique experimental techniques in SECUF play a crucial role in investigating the physical properties of this novel unconventional superconductor.
