A Sharp Phase Transition for Killed Branching Random Walks with Heavy-Tailed Displacements
Ramkrishna Jyoti Samanta
We study the survival of a branching random walk in a supercritical Galton-Watson tree subject to a deterministic, superlinear killing barrier with heavy-tailed displacements. For…

Long-term behaviour of refracted Lévy processes in a half-line
Ramkrishna Jyoti Samanta, Alexander R. Watson
We study the long-term behaviour of refracted Lévy processes within a half-line, with killing on exiting the domain and at state-dependent rate inside it. We identify the decay rat…

Mixing Phases and Metastability for the Glauber Dynamics on the p-Spin Curie-Weiss Model
Ramkrishna Jyoti Samanta, Somabha Mukherjee, Jiang Zhang
The Glauber dynamics for the classical -spin Curie-Weiss model on nodes with inverse temperature and zero external field is known to mix in time for $β< \fr…
