Quantum Trick Transforms Material Magnetism Sans Lasers

Theoretical physicists have discovered a laser-free method to control the magnetism of α-RuCl3, a thin material, by utilizing the electromagnetic fluctuations within an optical cavity. This breakthrough approach allows for the alteration of a material's magnetic properties solely through quantum fluctuations, providing a promising avenue for advancements in material science without the heat-related issues associated with intense laser methods. The researchers hope that this technique will enable the exploration of new material phases and enhance our understanding of the interplay between light and matter.

"Photon-mediated interactions enable tuning of density waves in quantum matter"

Scientists at EPFL and the University of Innsbruck have made a breakthrough in creating a crystalline structure called a "density wave" in an atomic gas, which can help us better understand the behavior of quantum matter. The researchers used an optical cavity to cause the particles in the Fermi gas to interact at long distance, allowing the atoms to collectively organize into a density wave pattern. This breakthrough can impact not only quantum research but quantum-based technologies in the future, such as high-temperature superconductivity and quantum computers.

"Breakthrough Discovery: Atoms Made Transparent to Select Light Frequencies"

A new phenomenon called "collectively induced transparency" (CIT) has been discovered, causing groups of atoms to become transparent to specific frequencies of light. The transparency window is the result of interactions between groups of atoms and light in an optical cavity. This discovery expands our understanding of quantum effects and has the potential to pave the way for more efficient quantum memories.
