Open Quadratic Fermion Systems and Algebras of Affine Transformations
Hiroshi Tamura
We study evolution of open quadratic fermion systems in the framework of the quantum Markovian semigroup approach. We show that the algebra concerning commutators of Liouvillians f…
Dynamics of an Open System for Repeated Harmonic Perturbation
Hiroshi Tamura, Valentin A. Zagrebnov
We use the Kossakowski-Lindblad-Davies formalism to consider an open system defined as the Markovian extension of one-mode quantum oscillator S, perturbed by a piecewise stationary…
Random point field approach to analysis of anisotropic Bose-Einstein condensations
Hiroshi Tamura, Valentin A. Zagrebnov
Position distributions of constituent particles of the perfect Bose-gas trapped in exponentially and polynomially anisotropic boxes are investigated by means of the boson random po…
Large Deviation Principle for Non-Interacting Boson Random Point Processes
Hiroshi Tamura, Valentin Zagrebnov
Limit theorems, including the large deviation principle, are established for random point processes (fields), which describe the position distributions of the perfect boson gas in…
Mean-Field Interacting Boson Random Point Fields in Weak Harmonic Traps
Hiroshi Tamura, Valentin Zagrebnov
A model of the mean-field interacting boson gas trapped by a weak harmonic potential is considered by the \textit{boson random point fields} methods. We prove that in the Weak Harm…
Random Point Fields for Para-Partcles of Any Order
Hiroshi Tamura, Keiichi R. Ito
Random point fields which describe gases consisting of para-particles of any order are given by means of the canonical ensemble approach. The analysis for the cases of the para-fer…
