MOG as symmetry breaking in Scalar-Vector-Tensor gravity
Shahin Rouhani, Sohrab Rahvar
The Modified Gravity Model (MOG) has been proposed as a solution to the dark matter problem, but it does not meet the gauge invariant condition. The aim of this work is to propose…
Collective Movement with Signaling
Mohammad Salahshour, Shahin Rouhani
We consider a population of mobile agents able to make noisy observation of the environment and communicate their observation by production and comprehension of signals. Individual…
Connection probabilities in the double-dimer model -- the case of two connectivity patterns
Nahid Ghodratipour, Shahin Rouhani
We apply the Grassmannian representation of the dimer model, an equivalent approach to Kasteleyn's solution to the close-packed dimer problem, to calculate the connection probabili…
Resilience of Majorana Fermions in the face of Disorder
Alireza Habibi, S. A. Jafari, S. Rouhani
We elucidate the reduction of the winding number (WN) caused by the onsite disorder in a higher WN next nearest neighbor XY model. When disorder becomes strong enough, Majorana edg…
The expectation value of the number of loops and the left-passage probability in the double-dimer model
Nahid Ghodratipour, Shahin Rouhani
We study various statistical properties of the double-dimer model, a generalization of the dimer model, on rectangular domains of the square lattice. We take advantage of the Grass…
Evolutionary value of collective sensing
Mohammad Salahshour, Shahin Rouhani
We propose a mathematical model for collective sensing in a population growing in a stochastically varying environment. In the population, individuals use an information channel fo…
