Coherent control of quantum tunneling in different driving-frequency regions

We investigate the coherent control of quantum tunneling for a single particle held in a driven double-well potential. For a moderate-frequency region, we demonstrate that the irregular quantum

Driven Tunneling: Chaos and Decoherence

Chaotic tunneling in a driven double-well system is investigated in absence as well as in the presence of dissipation. As the constitutive mechanism of chaos-assisted tunneling, we focus on the

Quantum dynamics in strong fluctuating fields

A large number of multifaceted quantum transport processes in molecular systems and physical nanosystems, such as e.g. nonadiabatic electron transfer in proteins, can be treated in terms of quantum

Heat-exchange statistics in driven open quantum systems

As the dimensions of physical systems approach the nanoscale, the laws of thermodynamics must be reconsidered due to the increased importance of fluctuations and quantum effects. While the

Relaxation in charge-transfer systems with very large tunnel splitting: A semiclassical stochastic approach

Electron transfer in strongly coupled systems, appropriate to mixed-valence compounds, is studied to explore the competition between electronic coherence and dissipation. A set of stochastic

Tunneling in a bistable system under rapid pumping

With this work, I demonstrate the influence of a highly oscillating external field on the coherent tunneling of a quartic double-well potential. Extensive investigation on the tunneling rate of such

Chaotic tunneling in a laser field

We study the driven tunneling of a one-dimensional charged particle confined to a rectangular double well. The numerical simulation of the Schrödinger equation based on the Cranck-Nicholson



Damped periodically driven quantum transport in bistable systems

The quantum dynamics of a quartic double well, subjected to a harmonically oscillating field, is studied in the framework of the Floquet formalism. The modifications of the familiar tunneling process

Zener transitions in dissipative driven systems.

The effect of inelastic interactions on Zener transitions is studied in the context of externally driven systems (flux-driven normal metallic rings, current-biased tunnel junctions, etc.). We employ

The mechanism of coherent destruction of tunneling is studied from the viewpoint of quantum optics by considering the photon statistics of a single mode cavity field which is strongly coupled to a two-level tunneling system (TS).

Low temperature tunneling dynamics in condensed media

There has been considerable interest recently in the low temperature dynamics of condensed phase tunneling phenomena. In this paper we consider the interplay between quasiparticle transport and

Stabilization of localized states in dissipative tunneling systems interacting with monochromatic fields

We study the dynamics of an initially localized symmetric two-level system coupled to high-temperature dissipative environments and driven by a strong time-periodic force which corresponds to

Bridge‐assisted electron transfer driven by dichotomically fluctuating tunneling coupling

The influence of dichotomically fluctuating tunneling coupling on long‐range electron transfer is studied theoretically. Within an approach similar to the noninteracting blip approximation known from

Dynamical Hysteresis in Bistable Quantum Systems

We are studying bistable quantum systems coupled to a thermal environment in the presence of an external controlling force. The impact of thermal and quantum effects on the switching hysteresis is
