Negative large deviations of the front velocity of -particle branching Brownian motion
Baruch Meerson, Pavel V. Sasorov
We study negative large deviations of the long-time empirical front velocity of the center of mass of the one-sided -BBM (-particle branching Brownian motion) system in one d…

Fractional Brownian motion in confining potentials: non-equilibrium distribution tails and optimal fluctuations
Baruch Meerson, Pavel V. Sasorov
At long times, a fractional Brownian particle in a confining external potential reaches a non-equilibrium (non-Boltzmann) steady state. Here we consider scale-invariant power-law p…
