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. The movement of electrons in a lattice ...

Quantum geometry describes quantum states in systems with changing system parameters, such as an electron spinning in a magnetic field whose direction is slowly changing. The state of the electron ...

A hidden quantum geometry that distorts electron paths has finally been observed in real materials. This “quantum metric,” once thought purely theoretical, may revolutionize electronics, ...

Quantum geometry gives rise to many fascinating phenomena in solids that go beyond Landau theory. A general framework is now introduced to measure the quantum geometric tensor in solids — a ...

New quantum geometry leap: Scientists applied quantum geometry to non-Hermitian photonic systems, adding control over light's intensity and trajectory. Direct metric measurement: The team developed an ...

Describing natural phenomena with geometric language is one of the most important achievements of modern physics. In the context of general relativity, Einstein treats spacetime as a dynamic geometric ...

Quantum materials can be loosely defined as materials for which quantum mechanical effects manifest on a macroscopic scale. Two classes of quantum materials are paradigmatic: superconductors, and ...

How can data be processed at lightning speed, or electricity conducted without loss? To achieve this, scientists and industry alike are turning to quantum materials, governed by the laws of the ...

A physics professor at the University of Nevada, Reno and his colleagues have identified quantum geometry as an opportunity to increase the superconducting temperature of two-dimensional ...

Study demonstrates a chiral fermionic valve that separates handedness via quantum geometry, enabling transport and interference without magnetic fields. (Nanowerk News) A collaboration between Stuart ...
