Light effect in photoionization of traps in GaN MESFETs
H. Arabshahi, A. Binesh
Trapping of hot electron behavior by trap centers located in buffer layer of a wurtzite phase GaN MESFET has been simulated using an ensemble Monte Carlo simulation. The results of…
The Non-Abelian Tensor Square and Schur multiplier of Groups of Orders , and
S. H. Jafari, P. Niroomand, A. Erfanian
The aim of this paper is to determine the non-abelian tensor square and Schur multiplier of groups of square free order and of groups of orders , and , where $p…
Reverse triangle inequality in Hilbert -modules
M. Khosravi, H. Mahyar, M. S. Moslehian
We prove several versions of reverse triangle inequality in Hilbert -modules. We show that if are vectors in a Hilbert module over a -alge…
Some considerations on the nonabelian tensor square of crystallographic groups
Ahmad Erfanian, Francesco G. Russo, Nor Haniza Sarmin
The nonabelian tensor square of a polycyclic group is a polycyclic group and its structure arouses interest in many contexts. The same assertion is still true for…
T-duality of curvature terms in D-brane actions
Mohammad R. Garousi
We examine the known curvature terms in the DBI part of the D-brane action under the T-duality transformation. Using the compatibility of the action with the standard rules of T-du…
Collective coordinate variable for soliton-potential system in sine-Gordon model
Kurosh Javidan
A Collective coordinate variable for adding a space dependent potential to the sine-Gordon model is presented. Interaction of solitons with a delta function potential barrier and a…
Measurable lower bounds on concurrence
Iman Sargolzahi, Sayyed Yahya Mirafzali, Mohsen Sarbishaei
We derive measurable lower bounds on concurrence of arbitrary mixed states, for both bipartite and multipartite cases. First, we construct measurable lower bonds on the purely alge…
The role of thermal conduction in magnetized viscous-resistive ADAFs
J. Ghanbari, S. Abbassi, M. Ghasemnezhad
Observations of the hot gas, which is surrounding Sgr A* and a few other nearby galactic nuclei, imply that mean free paths of electron and proton are comparable to gas capture rad…
Module homomorphisms and multipliers on locally compact quantum groups
M. Ramezanpour, H. R. E. Vishki
For a Banach algebra with a bounded approximate identity, we investigate the -module homomorphisms of certain introverted subspaces of , and show that all -module ho…
Extremal rotating solutions in Horava Gravity
Ahmad Ghodsi, Ehsan Hatefi
Recently a new four-dimensional non relativistic renormalizable theory of gravity was proposed by Horava. In this paper we have found different near horizon geometries in Horava gr…
Bessel type inequalities in Hilbert C*-modules
S. S. Dragomir, M. Khosravi, M. S. Moslehian
Regarding the generalizations of the Bessel inequality in Hilbert spaces which are due to Bombiari and Boas--Bellman, we obtain a version of the Bessel inequality and some generali…
A treatment of the Cauchy--Schwarz inequality in -modules
LJ. Arambasic, D. Bakic, M. S. Moslehian
We study the Cauchy--Schwarz and some related inequalities in a semi-inner product module over a -algebra $\A$. The key idea is to consider a semi-inner product $\A$-module as…
Toroidal solutions in Horava Gravity
Ahmad Ghodsi
Recently a new four-dimensional non relativistic renormalizable theory of gravity was proposed by Horava. This gravity reduces to Einstein gravity at large distances. In this paper…
Filters and Semigroup Compactification Properties
M. Akbari Tootkaboni, H. R. E. Vishki
Stone-ech compactifications derived from a discrete semigroup can be considered as the spectrum of the algebra or as a collection of ultrafilters on…
Skew product dynamical systems, Ellis groups and topological centre
A. Jabbari, H. R. E. Vishki
In this paper, a general construction of a skew product dynamical system, for which the skew product dynamical system studied by Hahn is a special case, is given. Then the ergodic…
The Spatial Distribution Function of Galaxies at High Redshift
Hadi Rahmani, William C. Saslaw, Saeed Tavasoli
This is the first exploration of the galaxy distribution function at redshifts greater than about 0.1. Redshifts are based on the North and South GOODS Catalogs. In each catalog we…
The RN/CFT Correspondence
Mohammad R. Garousi, Ahmad Ghodsi
Recently it has been shown in 0901.0931 [hep-th] that the approach to extremality for the non-extremal Reissner-Nordstrom black hole is not continuous. The non-extremal RN black ho…
More on WZ action of non-BPS branes
Mohammad R. Garousi, Ehsan Hatefi
We calculate the disk level S-matrix element of one Ramond-Ramond, two gauge fields and one tachyon vertex operators in the world volume of non-BPS branes. We then find the momentu…
Non-relativistic D3-brane in the presence of higher derivative corrections
Mohsen Alishahiha, Ahmad Ghodsi
Using alpha'^3 terms of type IIB supergravity action we study higher order corrections to the non-relativistic non-extremal D3-brane. Utilizing the corrected solution we evaluate c…
