Quantum decoherence of the damped harmonic oscillator
A. Isar
In the framework of the Lindblad theory for open quantum systems, we determine the degree of quantum decoherence of a harmonic oscillator interacting with a thermal bath. It is fou…
Purity and decoherence in the theory of a damped harmonic oscillator
A. Isar, A. Sandulescu, W. Scheid
For the generalized master equations derived by Karrlein and Grabert for the microscopic model of a damped harmonic oscillator, the conditions for purity of states are written, in…
Purity of states in the theory of open quantum systems
A. Isar
The condition of purity of states for a damped harmonic oscillator is considered in the framework of Lindblad theory for open quantum systems. For a special choice of the environme…
On the damping of the angular momentum of three harmonic oscillators
A. Isar, A. Sandulescu
In the frame of the Lindblad theory of open quantum systems, the system of three uncoupled harmonic oscillators with opening operators linear in the coordinates and momenta of the…
Damped quantum harmonic oscillator
A. Isar, A. Sandulescu
In the framework of the Lindblad theory for open quantum systems the damping of the harmonic oscillator is studied. A generalization of the fundamental constraints on quantum mecha…
