Quantum Annealer Improves Understanding of Quantum Many-Body Systems

Physicists have long been pursuing the idea of simulating quantum particles with a computer that is itself made up of quantum particles. This is exactly what scientists at Forschungszentrum Jülich have done together with colleagues from Slovenia. They used a quantum annealer to model a real-life quantum material and showed that the quantum annealer can directly mirror the microscopic interactions of electrons in the material.

Researchers find first experimental evidence for a graviton-like particle in a quantum material

A team of scientists from Columbia, Nanjing University, Princeton, and the University of Munster, writing in the journal Nature, have presented the first experimental evidence of collective excitations with spin called chiral graviton modes (CGMs) in a semiconducting material.

"Here, we realize a Fermi gas featuring both strong, tunable contact interactions and #photon-mediated, spatially structured long-range interactions in a transversely driven high-finesse #optical cavity. Above a critical long-range interaction strength, density #wave order is stabilized in the system, which we identify via its #superradiant light-#scattering properties."

Density-wave ordering in a unitary Fermi gas with photon-mediated interactions - Nature

An experiment with atoms and photons provides a fully tunable and microscopically controllable platform for the experimental study of the interplay of superfluidity and density-wave order.
