Coherent states for the harmonic oscillator with time-dependent mass and frequency
A. D. Jannussis,B.S. Bartzis +1 more
TL;DR: In this paper, exact coherent states for a damped harmonic oscillator with time-dependent mass and frequency were constructed, and the new coherent states result exactly as partial cases of the coherent states of Yuen which are equivalent to the well-known squeezed states.
Journal ArticleDOI
Propagator with friction in quantum mechanics
TL;DR: In this article, the propagator of a quantum-mechanical system with friction was calculated in quadratic form for the case where the friction is a linear function of the velocity with a friction constant.
Journal ArticleDOI
Quantum groups and Lie-admissible time evolution
TL;DR: In this paper, the time evolution of operators for q-oscillators is derived for the first time by exploiting the connection between q-deformation algebras and Lie-admissible alges.
Journal ArticleDOI
Bose realization of a non-canonical Heisenberg algebra
TL;DR: In this article, the Bose realization of a generalized Heisenberg algebra, in which the bracket of the annihilation and creation operators is proportional to a polynomial function of the number operator, is studied.
