Light-matter interactions can induce phases and physics not observable in the equilibrium regime of a quantum material but understanding the underlying mechanisms can be challenging. Here, the authors show a generalised Gibbs ensemble applied to phot

By combining inelastic neutron scattering and numerical simulations, we study the quasi-one-dimensional Ising-like quantum antiferromagnet BaCo_{2}V_{2}O_{8} in a longitudinal magnetic field applied along the Ising anisotropy, which is also the chain

We study the dynamics of the quasi-one-dimensional Ising-Heisenberg antiferromagnet BaCo_{2}V_{2}O_{8} under a transverse magnetic field. Combining inelastic neutron scattering experiments and theoretical analyses by field theories and numerical simu

We study the tunneling mechanism of nonlinear optical processes in solids induced by strong coherent laser fields. The theory is based on an extension of the Landau-Zener model with nonadiabatic geometric effects. In addition to the rectification eff

This article is meant as a gentle introduction to the topological terms that often play a decisive role in effective theories describing topological quantum effects in condensed matter systems. We first take up several prominent examples, mainly from

We study the transport properties of a one dimensional quantum system with disorder. We numerically compute the frequency dependence of the conductivity of a fermionic chain with nearest neighbor interaction and a random chemical potential by using t

We present a theory of Mott memristors whose working principle is the non-linear carrier avalanche multiplication in Mott insulators subject to strong electric fields. The internal state of the memristor, which determines its resistance, is encoded i

We propose a local detection scheme for the Majorana zero mode (MZM) carried by a vison in Kitaev's chiral spin liquid (CSL) using scanning tunneling microscopy (STM). The STM introduces a single Majorana into the system through hole-charge injection

The optical conductivity contains relevant information on the properties of correlated electron systems. In infinite dimensions, where dynamical mean field theory becomes exact, vertex corrections can be neglected and the conductivity computed from p
