Exceptional points in open and PT symmetric systems
Hichem Eleuch, Ingrid Rotter
Exceptional points (EPs) determine the dynamics of open quantum systems and cause also PT symmetry breaking in PT symmetric systems. From a mathematical point of view, this is caus…
Open quantum systems and Dicke superradiance
Hichem Eleuch, Ingrid Rotter
We study generic features of open quantum systems embedded into a continuum of scattering wavefunctions and compare them with results discussed in optics. A dynamical phase transit…
Width bifurcation and dynamical phase transitions in open quantum systems
Hichem Eleuch, Ingrid Rotter
The states of an open quantum system are coupled via the environment of scattering wavefunctions. The complex coupling coefficients between system and environment arise from th…
Enhancement of photon intensity in forced coupled quantum wells inside a semiconductor microcavity
Hichem Eleuch, Awadhesh Prasad, Ingrid Rotter
We study numerically the photon emission from a semiconductor microcavity containing quantum wells under the influence of a periodic external forcing. The emission is dete…
