Speeding up Brownian escape via intermediate finite potential barriers
Vishwajeet Kumar, Ohad Shpielberg, Arnab Pal
The mean first-passage time (MFPT) for a Brownian particle to surmount a potential barrier of height is a fundamental quantity governing a wide array of physical and chemical…
Inferring intermediate states by leveraging the many-body Arrhenius law
Vishwajeet Kumar, Arnab Pal, Ohad Shpielberg
Metastable states appear as long-lived intermediate states in various natural transport phenomena which are governed by energy landscapes. As such, these intermediate metastable st…
Emerging universality classes in thermally-assisted activation of interacting diffusive systems: A perturbative hydrodynamic approach
Vishwajeet Kumar, Arnab Pal, Ohad Shpielberg
Thermal activation of a particle from a deep potential trap follows the Arrhenius law. Recently, this result was generalized for interacting diffusive particles in the trap, reveal…
Arrhenius law for interacting diffusive systems
Vishwajeet Kumar, Arnab Pal, Ohad Shpielberg
Finding the mean time it takes for a particle to escape from a meta-stable state due to thermal fluctuations is a fundamental problem in physics, chemistry and biology. For weak th…
