A Neuronal Model at the Edge of Criticality: An Ising-Inspired Approach to Brain Dynamics
Sajedeh Sarmastani, Maliheh Ghodrat, Yousef Jamali
We present a neuronal network model inspired by the Ising model, where each neuron is a binary spin () interacting with its neighbors on a 2D lattice. Updates are async…
Activity-induced asymmetric dispersion in confined channels with constriction
Armin Maleki, Malihe Ghodrat, Ignacio Pagonabarraga
Microorganisms, such as E.Coli, are known to display upstream behavior and respond rheotactically to shear flows. In particular, E.Coli suspensions have been shown to display stron…
Transport coefficients for hard-sphere relativistic gas
Malihe Ghodrat
Transport coefficients are of crucial importance in theoretical as well as experimental studies. Despite substantial research on classical hard sphere/disk gases in low and high de…
A molecular dynamics approach to dissipative relativistic hydrodynamics: propagation of fluctuations
Leila Shahsavar, Malihe Ghodrat, Afshin Montakhab
Relativistic generalization of hydrodynamic theory has attracted much attention from a theoretical point of view. However, it has many important practical applications in high ener…
Ion-mediated interactions between net-neutral slabs: Weak and strong disorder effects
Malihe Ghodrat, Ali Naji, Haniyeh Komaie-Moghaddam +1
We investigate the effective interaction between two randomly charged but otherwise net-neutral, planar dielectric slabs immersed in an asymmetric Coulomb fluid containing a mixtur…
Strong coupling electrostatics for randomly charged surfaces: Antifragility and effective interactions
Malihe Ghodrat, Ali Naji, Haniyeh Komaie-Moghaddam +1
We study the effective interaction mediated by strongly coupled Coulomb fluids between dielectric surfaces carrying quenched, random monopolar charges with equal mean and variance,…
Asymmetric Coulomb fluids at randomly charged dielectric interfaces: Anti-fragility, overcharging and charge inversion
Ali Naji, Malihe Ghodrat, Haniyeh Komaie-Moghaddam +1
We study the distribution of multivalent counterions next to a dielectric slab, bearing a quenched, random distribution of charges on one of its solution interfaces, with a given m…
Thermodynamics of a morphological transition in a relativistic gas
Afshin Montakhab, Leila Shahsavar, Malihe Ghodrat
Recently, a morphological transition in the velocity distribution of a relativistic gas has been pointed out which shows hallmarks of a critical phenomenon. Here, we provide a gene…
Heat transport and diffusion in a canonical model of a relativistic gas
Malihe Ghodrat, Afshin Montakhab
Relativistic transport phenomena are important from both theoretical and practical point of view. Accordingly, hydrodynamics of relativistic gas has been extensively studied theore…
Time parameterization and stationary distributions in a relativistic gas
Malihe Ghodrat, Afshin Montakhab
In this paper we consider the effect of different time parameterizations on the stationary velocity distribution function for a relativistic gas. We clarify the distinction between…
Statistical thermodynamics of a two dimensional relativistic gas
Afshin Montakhab, Malihe Ghodrat, Mahmood Barati
In this article we study a fully relativistic model of a two dimensional hard-disk gas. This model avoids the general problems associated with relativistic particle collisions and…
