Kink-kink correlations in nonlinear quenches across a quantum critical point
Lakshita Jindal, Kavita Jain
When a quantum system exhibiting a second order phase transition is quenched across the critical point in large but finite time, the dynamics are not adiabatic in the critical regi…
Dynamics of fixation probability in a population with fluctuating size
Kavita Jain, Hitesh Sumuni
In many biological processes, the size of a population changes stochastically with time, and recent work in the context of cancer and bacterial growth have focused on the situation…
Current fluctuations in the symmetric zero-range process below and at critical density
Tanmoy Chakraborty, Punyabrata Pradhan, Kavita Jain
Characterizing current fluctuations in a steady state is of fundamental interest and has attracted considerable attention in the recent past. However, the bulk of the studies are l…
Run-and-tumble particle with saturating rates
Kavita Jain, Sakuntala Chatterjee
We consider a run-and-tumble particle whose speed and tumbling rate are space-dependent on an infinite line. Unlike most of the previous work on such models, here we make the physi…
Kibble-Zurek scalings and coarsening laws in slowly quenched classical Ising chains
Lakshita Jindal, Kavita Jain
We consider a one-dimensional classical ferromagnetic Ising model when it is quenched from a low temperature to zero temperature in finite time using Glauber or Kawasaki dynamics.…
Number of adaptive steps to a local fitness peak
Kavita Jain
We consider a population of genotype sequences evolving on a rugged fitness landscape with many local fitness peaks. The population walks uphill until it encounters a local fitness…
