New theory links quantum geometry to electron-phonon coupling
A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions.

In physics, nonreciprocity occurs when a system's response varies depending on the direction in which waves or signals are propagating within it. This asymmetry arises from a break in so-called time-reversal symmetry, which ...
Deep under the ground at Fermi National Accelerator Laboratory is a brand-new quantum sensor and computing research center called QUIET, and at the surface—100 meters above—sits its twin called LOUD.

The accelerated expansion of the present universe, believed to be driven by a mysterious dark energy, is one of the greatest puzzles in our understanding of the cosmos. The standard model of cosmology called Lambda-CDM, explains ...
Many of today's quantum devices rely on collections of qubits, also called spins. These quantum bits have only two energy levels, the "0" and the "1." However, spins in real devices also interact with light and vibrations ...
