Motion of a charged particle in the magnetic dipole field
Jian Qi Shen
This note discusses the motion of a charged particle in the magnetic dipole field and a modified Barut's lepton mass formula. It is shown that a charged particle in the magnetic di…
An approach to the time-dependent Jaynes-Cummings model without the rotating wave approximation
Jian Qi Shen
This report presents an approach to the exact solutions of the time-dependent Jaynes-Cummings (J-C) model without the rotating wave approximation (RWA). It is shown that there is a…
The su(n) Lie algebraic structures in the Pegg-Barnett quantization formulation
Jian-Qi Shen
We investigate the oscillator algebra of the Pegg-Barnett oscillator with a finite-dimensional number-state space and show that it possesses the su() Lie algebraic structure. In…
Comment on "Solutions of the Schrödinger equation for the time-dependent linear potential''
Jian Qi Shen
We show that the solution obtained by Bekkar {\it et al.} in their comment [Phys. Rev. A {\bf 68}, 016101 (2003)] on Guedes's work of solving the quantum system with a time-depende…
Solutions of the Schrödinger equation for the time-dependent linear potential
Jian Qi Shen
By making use of the Lewis-Riesenfeld invariant theory, the solution of the Schrödinger equation for the time-dependent linear potential corresponding to the quadratic-form Lewis-R…
The Connection Between Density Matrix Method, Supersymmetric Quantum Mechanics and Lewis-Riesenfeld Invariant Theory
Jian Qi Shen
This paper is concerned with the connection between density matrix method, supersymmetric quantum mechanics and Lewis-Riesenfeld invariant theory. It is shown that these three form…
