Quantum Theory of Fields and Properties of Quantum Systems
... The use of real scalar field for describing neutral bosons of spin zero in the trap has given a good agreement with the experiment. It is the same with Dirac field in the study of electron gas in a metal. The complex ...

Interaction of quantum systems with environment in QCD
... Developing the analogy with QO it can be shown that the two-mode (in particular, collinear) gluon squeezed states can be entangled ones [25]. Such gluon states can lead to q q- ¯ entangled ones. Interaction of the quark ...

Dynamics and simulation of open quantum systems
... We investigate the behavior of a simple non-Markovian process in order to understand how to con- struct a generic approach for real-time, open-system dynamics. The process we consider is amplitude damping of a spin. ...
