Time evolution, cyclic solutions and geometric phases for the generalized time-dependent harmonic oscillator
Qiong-Gui Lin
The generalized time-dependent harmonic oscillator is studied. Though several approaches to the solution of this model have been available, yet a new approach is presented here, wh…
Time evolution, cyclic solutions and geometric phases for general spin in an arbitrarily varying magnetic field
Qiong-Gui Lin
A neutral particle with general spin and magnetic moment moving in an arbitrarily varying magnetic field is studied. The time evolution operator for the Schrödinger equation can be…
Anisotropic harmonic oscillator in a static electromagnetic field
Qiong-Gui Lin
A nonrelativistic charged particle moving in an anisotropic harmonic oscillator potential plus a homogeneous static electromagnetic field is studied. Several configurations of the…
Wave packets of a harmonic oscillator with various degrees of rigidity
Qiong-Gui Lin
The time evolution of wave packets in a harmonic oscillator potential is studied. Some new results for the most general case are obtained. A natural number, called ``degree of rigi…
Geometric phases for wave packets in a uniform magnetic field
Qiong-Gui Lin
A wave packet of a charged particle always make cyclic circular motion in a uniform magnetic field, just like a classical particle. The nonadiabatic geometric phase for an arbitrar…
Geometric phases for neutral and charged particles in a time-dependent magnetic field
Qiong-gui Lin
It is well known that any cyclic solution of a spin 1/2 neutral particle moving in an arbitrary magnetic field has a nonadiabatic geometric phase proportional to the solid angle su…
