Electron–phonon interactions underpin a diverse range of phenomena in quantum many-body systems. These interactions, whereby electrons couple with lattice vibrations (phonons), are central to ...

Gao Peng's research group at the International Center for Quantum Materials, School of Physics, Peking University, has developed a breakthrough method for visualizing interfacial phonon transport with ...

Add Yahoo as a preferred source to see more of our stories on Google. Researchers at Rice University and their collaborators have achieved a groundbreaking demonstration of strong interference between ...

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 ...

Researchers experimentally confirm their 2021 hypothesis that electron-phonon coupling, not electron-electron interactions, ...

What’s long been seen as a hindrance to electrical conduction in semiconductors may actually be an asset, at least in two-dimensional materials. The research team found that in atomically thin ...

Caltech scientists have developed an artificial intelligence (AI)–based method that dramatically speeds up calculations of the quantum interactions that take place in materials. In new work, the group ...

Illustration of a polaron in a crystal: the central bright sphere is the charge carrier, distorting the surrounding lattice. The wavy lines represent high-order Feynman diagrams for the ...

A theoretical framework published on the arXiv preprint server proposes that a new class of materials, called superconducting altermagnets, could generate and carry spin currents without any energy ...

Developing a unified theory for liquid behaviour has long been a challenge due to the complex interactions between particles and the constantly changing dynamic disorder within liquids. Current ...

Using an advanced Monte Carlo method, Caltech researchers found a way to tame the infinite complexity of Feynman diagrams and solve the long-standing polaron problem, unlocking deeper understanding of ...
