This report on progress explores recent advances in our theoretical and experimental
understanding of the physics of open quantum systems (OQSs). The study of such systems …

The relevance of the open quantum system formalism for the description of weakly bound
nuclei far from the valley of stability, small droplets of neutral atoms, gas of trapped atoms …

The intrinsic dynamics of a system with open decay channels is described by a non-
Hermitian effective Hamiltonian which at the same time allows one to find the external …

Zinc oxide (ZnO) is one of the most versatile semiconductors, and one-dimensional (1D)
ZnO nanostructures have attracted significant interest for use in ultraviolet (UV) lasers …

In a recent work the resonance widths in a microwave billiard with attached waveguide were
studied in dependence on the coupling strength [E. Persson et al., Phys. Rev. Lett. 85, 2478 …

Along with the studies of the properties of optical microcavities, the optical nonlinear effects
of the material and the interaction between light and matter are becoming important topics …

We analyze the transport phenomena of two-dimensional quantum billiards with convex
boundary of different shape. The quantum mechanical analysis is performed by means of …

We review properties of open chaotic mesoscopic systems with a finite Ehrenfest time τ E.
The Ehrenfest time separates a short-time regime of the quantum dynamics, where wave …

We study transmission through a system with N= 10 states coupled to K= 2 continua of
scattering wave functions in the framework of the S matrix theory by using the Feshbach …

The line shape of resonances in the overlapping regime is studied by using the eigenvalues
and eigenfunctions of the effective Hamiltonian of an open quantum system. A generalized …
