Since the pioneering works by Landau, Zener, Stückelberg, and Majorana (LZSM), it has
been known that driving a quantum two-level system results in tunneling between its states …

This article reviews theoretical methods developed in the last decade to understand cavity
quantum electrodynamics in the ultrastrong‐coupling regime, where the strength of the light …

Quantum two-level systems interacting with the surroundings are ubiquitous in nature. The
interaction suppresses quantum coherence and forces the system towards a steady state …

Permitting a more precise measurement to physical quantities than the classical limit by
using quantum resources, quantum metrology holds a promise in develo** many …

Greenberger-Horne-Zeilinger and W states feature genuine tripartite entanglement that
cannot be converted into each other by local operations and classical communication. Here …

The intricate relationship between topology and disorder in non-equilibrium quantum
systems presents a captivating avenue for exploring localization phenomenon. Here, we …

The stroboscopic evolution of a time-periodically driven isolated quantum system can
always be described by an effective time-independent Hamiltonian. Whether this concept …

We study the electronic contribution to the nonlinear optical response of the α-T 3 model.
This model is an interpolation between a graphene (α= 0) and dice (α= 1) lattice. Using a …

We theoretically investigate basic properties of nonequilibrium steady states of periodically-
driven open quantum systems based on the full solution of the Maxwell–Bloch equation. In a …

Floquet engineering of isolated systems is often based on the concept of the effective time-
independent Floquet Hamiltonian, which describes the stroboscopic evolution of a …
