The approach to thermal equilibrium, or thermalization, in isolated quantum systems is
among the most fundamental problems in statistical physics. Recent theoretical studies have …

Electronic states in quantum materials can be engineered by light irradiation, which is
greatly advanced by ab-initio computational predictions in realistic light-matter coupled …

Light-matter coupling involving classical and quantum light offers a wide range of
possibilities to tune the electronic properties of correlated quantum materials. Two …

A universal feature of topological insulators is that they cannot be adiabatically connected to
an atomic limit, where individual lattice sites are completely decoupled. This property is …

It is proved that the energy absorption in a periodically driven classical spin system is
exponentially slow in frequency, which results in a two-step relaxation called the Floquet …

We present a systematic study of the nonequilibrium steady states (NESS) in Mott insulators
driven by dc or ac electric fields, based on the Floquet dynamical mean-field theory. The …

We consider driving multiorbital Mott insulators using laser radiation. We derive general
expressions for periodically driven spin-orbital models using time-dependent perturbation …

A single Weyl fermion, which is prohibited in static lattice systems by the Nielsen-Ninomiya
theorem, is shown to be realized in a periodically driven three-dimensional lattice system …

We show that finite current in superconductors can induce topological phase transitions, as
a result of the deformation of the quasiparticle spectrum by a finite center-of-mass (COM) …

In metals containing magnetic impurities, conduction electrons screen the magnetic
impurities and induce the Kondo effect, ie, the enhancement of the electrical resistance at …
