Some general features of matrix product states in stochastic systems

V. Karimipour

We will prove certain general relations in Matrix Product Ansatz for one dimensional stochastic systems, which are true in both random and sequential updates. We will derive genera…

Geometrically Reduced Number of Protein Ground State Candidates

M. R. Ejtehadi, N. Hamedani, V. Shahrezaei

Geometrical properties of protein ground states are studied using an algebraic approach. It is shown that independent from inter-monomer interactions, the collection of ground stat…

A multi-species asymmetric exclusion process;steady state and correlation functions on a periodic lattice

V. karimipour

By generalizing the algebra of operators of the Asymmetric Simple Exclusion Process (ASEP), a multi-species ASEP in which particles can overtake each other,is defined on both open…

Noncommutative Geometry From Strings and Branes

F. Ardalan, H. Arfaei, M. M. Sheikh-Jabbari

Noncommutative torus compactification of Matrix model is shown to be a direct consequence of quantization of the open strings attached to a D-membrane with a non-vanishing backgrou…

A multi-species asymmetric simple exclusion process and its relation to traffic flow

V. Karimipour

Using the matrix product formalism we formulate a natural p-species generalization of the asymmetric simple exclusion process. In this model particles hop with their own specific r…

Interaction of Branes at Angles in M(atrix) Model

K. Kaviani, S. Parvizi, A. H. Fatollahi

Interactions of relatively rotated Dp-branes in 1, 2, 3 and 4 angles in M(atrix) model are calculated and it is found to be in agreement with string theory calculations. In 4 angle…
