Flux tube counting or Casimir scaling

Sedigheh Deldar, Shahnoosh Rafibakhsh

QCD confines quarks in all representations. From lattice calculations and fat center vortices model, we discuss that the coefficient of the linear term in the potential is proporti…

Massive spinor fields in flat spacetimes with non-trivial topology

N. Ahmadi, M. Nouri-Zonoz

The vacuum expectation value of the stress-energy tensor is calculated for spin massive fields in several multiply connected flat spacetimes. We examine the physical eff…

Directed Ligand Passage Over the Surface of Diffusion-Controlled Enzymes: A Cellular Automata Model

Mehrdad Ghaemi, Nasrollah Rezaei-Ghaleh, Mohammad-Nabi Sarbolouki

The rate-limiting step of some enzymatic reactions is a physical step, i.e. diffusion. The efficiency of such reactions can be improved through an increase in the arrival rate of t…

Confinement and fat-center-vortices model

Sedigheh Deldar

In this paper I review shortly potentials obtained for SU(2), SU(3) and SU(4) static sources from fat-center-vortices model. Results confirm the confinement of quarks in all three…

with Effective Field Theory

H. Sadeghi, S. Bayegan

The cross section of neutron-deuteron radiative capture is calculated at energies relevant to Big-Bang nucleosynthesis ( Kev) with pionless Ef…

SU(4) string tensions from the fat-center-vortices model

Sedigheh Deldar, Shahnoosh Rafibakhsh

The thick- or fat-center-vortices model has been applied to a calculation of the potentials between static sources of various SU(4) representations. For intermediate distances, a l…

Precision calculation for nucleon capture by deuteron with Effective Field Theory

S. Bayegan, H. sadeghi

We calculate the cross section for radiative capture of neutron by deuteron using Effective Field Theory(EFT). The calculation includes N2LO order and we compare our…

Phase determination in spin-polarized neutron specular reflectometry by using a magnetic substrate

S. Farhad Masoudi

The scattering length density profile for a thin film structure can be determined uniquely if both modulus and phase of the reflection coefficient is known. Here, we describe a met…

Hierarchy of piecewise non-linear maps with non-ergodicity behavior

M. A. Jafarizadeh, M. Foroutan, S. Behnia

We study the dynamics of hierarchy of piecewise maps generated by one-parameter families of trigonometric chaotic maps and one-parameter families of elliptic chaotic maps of $\math…

Constraint Algebra in Causal Loop Quantum Gravity

Fatimah Shojai, Ali Shojai

de-Broglie--Bohm causal interpretation of canonical quantum gravity in terms of Ashtekar new variables is built. The Poisson brackets of (deBroglie--Bohm) constraints are derived a…

Causal Loop Quantum Gravity and Cosmological Solutions

Ali Shojai, Fatimah Shojai

We shall present here the causal interpretation of canonical quantum gravity in terms of new variables. Then we shall apply it to the minisuperspace of cosmology. A vacuum solution…

Braided Cyclic Cocycles and Non-Associative Geometry

S. E. Akrami, S. Majid

We use monoidal category methods to study the noncommutative geometry of nonassociative algebras obtained by a Drinfeld-type cochain twist. These are the so-called quasialgebras an…

Large-N limit of the two-dimensoinal Yang-Mills theory on surfaces with boundaries

M. Alimohammadi, M. Khorrami

The large-N limit of the two-dimensional U Yang-Mills theory on an arbitrary orientable compact surface with boundaries is studied. It is shown that if the holonomies of the g…

Solvable multi-species reaction-diffusion processes, including the extended drop-push model

Masoud Alimohammadi

By considering the master equation of asymmetric exclusion process on a one-dimensional lattice, we obtain the most general boundary condition of the multi-species exclusion proces…

Characterizing local rings via homological dimensions and regular sequences

Shokrollah Salarian, Sean Sather-Wagstaff, Siamak Yassemi

Let (R,m) be a Noetherian local ring of depth d and C a semidualizing R-complex. Let M be a finite R-module and t an integer between 0 and d. If G_C-dimension of M/IM is finite for…
