Dynamics of open quantum systems
J. Okołowicz, M. Płoszajczak, I. Rotter
The coupling between the states of a system and the continuum into which it is embedded, induces correlations that are especially large in the short time scale. These correlations…
Shot noise and transport in small quantum cavities with large openings
R. G. Nazmitdinov, H. -S. Sim, H. Schomerus +1
We present a dynamical analysis of the transport through small quantum cavities with large openings. The systematic suppression of shot noise is used to distinguish direct, determi…
High-harmonic generation and periodic level crossings: time profile and control
C. Figueira de Morisson Faria, I Rotter
We investigate high-harmonic generation in closed systems, using the two-level atom as a simplified model. By means of a windowed Fourier transform of the time-dependent dipole acc…
Comment on "Experimental observation of the topological structure of exceptional points" [Phys.Rev.Lett. 86, 787 (2001]
I. Rotter
It is shown that the two experiments Dembowski et al., PRL 86, 787 (2001), and Lauber et al., PRL 72, 1004 (1994), prove the same topological singularity. The phase changes found i…
Branch points in the complex plane and information loss in quantum systems at high level density
I. Rotter
The mechanism of avoided level crossings in quantum systems is studied. It is traced back to the existence of branch points in the complex plane which influence the properties of r…
