We explore the prospects to control by use of time-dependent fields quantum transport
phenomena in nanoscale systems. In particular, we study for driven conductors the electron …

Stochastic resonance is by now a well studied phenomenon whereby certain nonlinear
systems, subject to weak input signals, have the property that the presentation of stochastic …

We discuss and give evidence for the existence of a new mechanism for quantum dynamical
tunneling. It may occur when a quantum system's underlying classical dynamics are far from …

With the exception of the harmonic oscillator, quantum wave packets usually spread as time
evolves. This is due to the non-linear character of the classical equations of motion which …

Periodically driven (Floquet) quantum systems have recently been a focus of nonequilibrium
physics by virtue of their rich dynamics. Time-periodic systems not only exhibit symmetries …

We investigate the dynamics of a driven two-level system (classical Rabi model) using the
counter-rotating-hybridized rotating-wave method (CHRW), which is a simple method based …

The Mollow triplet is a fundamental signature of quantum optics and has been observed in
numerous quantum systems. Although it arises in the “strong driving” regime of the …

In recent years, considerable experimental progress in the determination of the current-
voltage characteristics of molecular wires has been achieved. 1–4 In these experiments, a …

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

In the spectrum of systems showing chaos-assisted tunneling, three-state crossings are
formed when a chaotic singlet intersects a tunnel doublet. We study the dissipative quantum …
