Electron–phonon coupling is crucial for the existence of various phases of matter, in
particular superconductivity and density waves. Here, we devise a theory that incorporates …

Chiral materials, similarly to human hands, have distinguishable right-handed and left-
handed enantiomers which may behave differently in response to external stimuli. Here, we …

A wide range of unconventional transport phenomena has recently been observed in single-
crystal delafossite metals. Here, we present a theoretical framework to elucidate electron …

Whereas electron-phonon scattering relaxes the electron's momentum in metals, a perpetual
exchange of momentum between phonons and electrons may conserve total momentum …

We analyze from a microscopic point of view the thermoelectric transport properties of a type-
I Weyl semimetal driven by electron-electron interactions mediated by virtual phonons …

Anomalous transport of topological semimetals has generated significant interest for
applications in optoelectronics, nanoscale devices, and interconnects. Understanding the …

Efficient generation and manipulation of spin signals in a given material without invoking
external magnetism remain one of the challenges in spintronics. The spin Hall effect (SHE) …

The transition-metal tetrachalcogenides are a model system to explore the conjunction of
correlated electronic states such as charge density waves (CDWs) with topological phases …

The electronic structure of chiral crystal NbSi 2 is investigated using angle-resolved
photoelectron spectroscopy and density-functional theory calculations. In addition to the …

In this talk, I will present a pedagogical introduction of theoretical and computational
approaches to describe excited-states in quantum matter, and predicting emergent states …
