Dmitry Levkov


Research interests

Dr. Levkov is a research fellow of ITMP and Institute for Nuclear Research RAS. His scientific interests are shared between cosmology of ultra-light dark matter, black hole physics, instantons and semiclassical description of nonperturbative transitions in quantum field theory. He and his collaborators for the first time computed the probability of baryon number violation in electroweak particle collisions at colliders, were first to describe kinetic Bose-Einstein condensation of light dark matter due to gravitational interactions.
