Probabilities of rare events in product kernel aggregation: An exact formula and phase diagram
R. Goutham, R. Rajesh, V. Subashri +1
We present an exact method for calculating the large deviation function describing rare fluctuations in the number of particles for product-kernel aggregation. Starting from the ma…
Entropy of full covering of the kagome lattice by straight trimers
Deepak Dhar, Tiago J. Oliveira, R. Rajesh +2
We consider the number of ways all the sites of a kagome lattice can be covered by non-overlapping linear rigid rods where each rod covers 3 sites. We establish a 2-to-1 correspond…
Finite size scaling and edge effects in the Takayasu model of aggregation diffusion with input
Rohan Banerjee Ravindran, R. Rajesh
We analytically and numerically study the effect of finite spatial boundaries on the Takayasu model of diffusing and aggregating particles with steady monomer input in one dimensio…
Mpemba effect in the relaxation of an active Brownian particle in a trap without metastable states
Apurba Biswas, R. Rajesh
We explore the role of activity in the occurrence of the Mpemba effect within a system of an active colloid diffusing in a potential landscape devoid of metastable minimum. The Mpe…
