In this paper the scattering theory for such open systems is considered. First it is assumed that a single maximal dissipative operator A D in a Hilbert space ${mathfrak H}$ is used to describe an open quantum system. In this case the minimal self-adjoint dilation $widetilde K$ of A D...

Shell Model for Open Quantum Systems The effect of resonances and the non resonant scattering states can be considered in the open quantum system extension of the nuclear interacting shell model. In these lectures, we will review the fascinating adventure of the last decade... Marek,Ploszajczak ...
Time-dependent density-matrix propagation is used to demonstrate, in a schematic model of an open quantum system, that the complex potential approach and the Lindblad dissipative dynamics are not equivalent. While the former preserves coherence, it is destroyed in the Lindblad dissipative dynamics. Q...
The dynamics of an open quantum system [4] may also be revealed in the elastic scattering of halo nuclei [5] –a conventional core nucleus surrounded by a loosely bound halo of orbiting neutron(s) or proton(s), as the elastic channel (sub-system) strongly interacts with the continuum of...
For instance, O'Connell et al.1 realized single mechanical quantum excitation (phonon) control coupled to a qubit. Besides, the elaborate mechanical resonators can be also applied in the opto-mechanical system2,3, quantum motion4, gravitational wave detection5, and other fundamental physics6. ...
If that is the case, it may provide a method to demon- strate collective quantum effect. In conclusion, we have predicted an anomalous light scattering property associated with the complex topolog- ical edge modes supported in a near-PT -symmetric plasmonic system. Due to its special PT -...
A general connection between the characteristic function of a Lévy process and loss of coherence of the statistical operator describing the center of mass degrees of freedom of a quantum system interacting through momentum transfer events with an environment is established. The relationship with microphy...
At the thermodynamic limit (q = 0), the stability of the system is classified as follows: (1) stable region at S(0) > 0, (2) spinodal point at S(0) = infinitely large, and (3) unstable region at S(0) < 0. Approaching the spinodal point (including the critical point) from ...
