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 …

A transition between energy levels at an avoided crossing is known as a Landau–Zener
transition. When a two-level system (TLS) is subject to periodic driving with sufficiently large …

The efficiency of the future devices for quantum information processing is limited mostly by
the finite decoherence rates of the individual qubits and quantum gates. Recently …

Nonadiabatic transition is a highly multidisciplinary concept and phenomenon, constituting a
fundamental mechanism of state and phase changes in various dynamical processes of …

This review provides a bird's eye view over the development of the hierarchy of Davydov's
Ansätze and its applications in a variety of problems in computational physical chemistry …

Application of strong dc electric field to an insulator leads to quantum tunneling of electrons
from the valence band to the conduction band, which is a famous nonlinear response known …

We study numerically the dynamics of the Rabi Hamiltonian, which describes the interaction
of a single cavity mode and a two-level atom without the rotating wave approximation. We …

We study Landau-Zener transitions in a dissipative environment by means of the numerically
exact quasiadiabatic propagator path integral. It allows to cover the full range of the involved …

By introducing a temporal change time scale τ A (t) for the time-dependent system
Hamiltonian, a general formulation of the Markovian quantum master equation is given to go …

We introduce and apply a numerically exact method for investigating the real-time
dissipative dynamics of quantum impurities embedded in a macroscopic environment …
