Quantum states of hierarchic systems
The density matrix formalism which is widely used in the theory of measurements , quantum computing, quantum description of chemical and biological systems always imply the averaging over all states of the environment. In practice this is impossible because the environment of the system is the complement of this system to the whole Universe and contains infinitely many degrees of freedom. A nov...

The density matrix formalism which is widely used in the theory of measurements , quantum computing, quantum description of chemical and biological systems always imply the averaging over the states of the environment. In practice this is impossible because the environment U\S of the system S is the complement of this system to the whole Universe and contains infinitely many degrees of freedom....
متن کاملInterface states of quantum spin systems
We review recent results as well as ongoing work and open problems concerning interface states in quantum spin systems at zero and finite temperature.
متن کاملCoherent states of quantum non-linear systems
Quantum dynamics of integrable systems is discussed. Localized wave packets generalizing the conventional coherent states of minimal uncertainty are constructed. The wave packet moves along a certain trajectory and does not change its shape for times of order 1 h̄ . In this Letter we suggest that the definition of a coherent state should be related to the Hamiltonian.The conventional coherent st...
متن کاملStationary states of dissipative quantum systems
In this Letter we consider stationary states of dissipative quantum systems. We discuss stationary states of dissipative quantum systems, which coincide with stationary states of Hamiltonian quantum systems. Dissipative quantum systems with pure stationary states of linear harmonic oscillator are suggested. We discuss bifurcations of stationary states for dissipative quantum systems which are q...
