Downward shift of infrared conductivity spectral weight at the DDW transition: role of anisotropy

Rouzbeh Gerami, Chetan Nayak

We consider the motion of conductivity spectral weight at a finite-temperature phase transition at which density-wave (DDW) order develops. We show that there is a sh…

Criticality and oscillatory behavior in non-Markovian Contact Process

Rouzbeh Gerami

A Non-Markovian generalization of one-dimensional Contact Process (CP) is being introduced in which every particle has an age and will be annihilated at its maximum age . There…

A History-Dependent Stochastic Predator-Prey Model : Chaos and its Elimination

Rouzbeh Gerami, Mohammad R. Ejtehadi

A non-Markovian stochastic predator-prey model is introduced in which the prey are immobile plants and predators are diffusing herbivors. The model is studied by both mean-field ap…
