Quantum Dynamical Semigroups and Applications

摘要: In this text the authors develop quantum dynamics of open systems for a wide class irreversible processes starting from concept completely positive semigroups. This unified approach makes material easily accessible to non-specialists and provides an easy access practical applications. Written graduate students, book presents wealth useful examples; in particular, models unstable N-level are treated systematically considerable detail including new types generated Bloch-equations. The general theory is extensively summarized abstract dynamical maps those obtained by reduction Hamiltonian under Markovian approximation. Various methods determining semigroup generators corresponding master equations discussed time-dependent nonlinear generators. Further topics generalized H-theorem, detailed balance return equilibrium, discrete Boltzmann equation, Schrdinger spin relaxation waves, entropy production its generalization measure irreversibiblity.
