Coherent current states in mesoscopic four-terminal Josephson junction
Malek Zareyan, A. N. Omelyanchouk
A theory is offered for the ballistic 4-terminal Josephson junction. The studied system consists of a mesoscopic two-dimensional normal rectangular layer which is attached in each…
Melting of Flux Lines in an Alternating Parallel Current
Mohammad Kohandel, Mehran Kardar
We use a Langevin equation to examine the dynamics and fluctuations of a flux line (FL) in the presence of an {\it alternating longitudinal current} . The magnus…
Neutrino oscillation in a space-time with torsion
M. alimohammadi, A. Shariati
Using the Einstein-Cartan-Dirac theory, we study the effect of torsion on neutrino oscillation. We see that torsion cannot induce neutrino oscillation, but affects it whenever osci…
Logarithmic conformal field theories and AdS correspondence
A. M. Ghezelbash, M. Khorrami, A. Aghamohammadi
We generalize the Maldacena correspondence to the logarithmic conformal field theories. We study the correspondence between field theories in (d+1)-dimensional AdS space and the d-…
A two--parametric family of asymmetric exclusion processes and its exact solution
M. Alimohammadi, V. Karimipour, M. Khorrami
A two--parameter family of asymmetric exclusion processes for particles on a one-dimensional lattice is defined. The two parameters of the model control the driving force and an ef…
Integrals and static solutions of general relativistic Liouville's equation in post Newtonian approximation
V. Rezania, Y. Sobouti
The post-Newtonian approximation of general relativistic Liouville's equation is presented. Two integrals of it, generalizations of the classical energy and angular momentum, are o…
