Effect of electromagnetic fields on deformed AdS_5 models
Davoud Masoumi, Leila Shahkarami, Farid Charmchi
The response of a QCD-like gauge theory, holographically dual to a deformed model, to constant electromagnetic fields is thoroughly investigated. The calculations…
Confining D-Instanton Background in an External Electric Field
Leila Shahkarami, Farid Charmchi
Using holography, we discuss the effects of an external static electric field on the D3/D-instanton theory at zero-temperature, which is a quasi-confining theory, with confined qua…
Modified gravity one-loop partition function
Shahab Shahidi, Farid Charmchi, Zahra Haghani +1
The one-loop partition function of the gravity theory is obtained around AdS background. After suitable choice of the gauge condition and computation of the…
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…
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…
