Quantum phase space distributions in thermofield dynamics
It is shown that the the quantum phase space distributions corresponding to a density operator ρ can be expressed, in thermofield dynamics, as overlaps between the state | ρ > and ”thermal” coherent states. The usefulness of this approach is brought out in the context of a master equation describing a nonlinear oscillator for which exact expressions for the quantum phase distributions for an ar...

متن کاملThermofield Dynamics and Path-Integral Formalism
Thermofield Dynamics (TFD), a real time formalism for thermal quantum field theory, is formulated in terms of a path-integral approach following the Weinberg procedure. In order to assure precise rules for the development, we use a representation of Lie-algebras such that the TFD algebraic ingredients are derived, including the tilde conjugation rules. The association with the canonical formali...
متن کاملQuantum dynamics of the damped harmonic oscillator
The quantum theory of the damped harmonic oscillator has been a subject of continual investigation since the 1930s. The obstacle to quantization created by the dissipation of energy is usually dealt with by including a discrete set of additional harmonic oscillators as a reservoir. But a discrete reservoir cannot directly yield dynamics such as Ohmic damping (proportional to velocity) of the os...
متن کاملQuantum dynamics of a damped deformed oscillator
The interaction of a quantum deformed oscillator with the environment is studied deriving a master equation whose form strongly depends on the type of deformation. PACS number(s): 03.70.+k, 02.50.-r Quantum groups [1] introduced as a mathematical description of deformed Lie algebras have given the possibility to generalize the notion of creation and annihiliation operators of the usual oscillat...
