Non-adiabatic Non-cyclic Generalization of the Berry Phase for a Spin-1/2 Particle in a Rotating Magnetic Field
Siamak S. Gousheh, Azadeh Mohammadi, Leila Shahkarami
In this paper we define a non-dynamical phase for a spin-1/2 particle in a rotating magnetic field in the non-adiabatic non-cyclic case, and this phase can be considered as a gener…
An Investigation of the Casimir Energy for a Fermion Coupled to the Sine-Gordon Soliton with Parity Decomposition
Siamak S. Gousheh, Azadeh Mohammadi, Leila Shahkarami
We consider a fermion chirally coupled to a prescribed pseudoscalar field in the form of the soliton of the sine-Gordon model and calculate and investigate the Casimir energy and a…
Casimir Energy for a Coupled Fermion-Soliton System
Leila Shahkarami, Azadeh Mohammadi, Siamak Sadat Gousheh
In this paper we compute the Casimir energy for a coupled fermion-pseudoscalar field system. In the model considered in this paper the pseudoscalar field is \textit{static} and \te…
Casimir Energy for a Coupled Fermion-Kink System and its stability
Siamak Sadat Gousheh, Azadeh Mohammadi, Leila Shahkarami
We compute the Casimir energy for a system consisting of a fermion and a pseudoscalar field in the form of a prescribed kink. This model is not exactly solvable and we use the phas…
