Expertise

Theoretical Condensed Matter PhysicsProfile

Professor Bulbul Chakraborty is a condensed matter theorist who is interested in systems far from equilibrium. Her recent research has been focused on a) exploring emergence in the macroworld where thermal fluctuations are irrelevant, and specifically how shearing leads to solidification in the natural world, b) analyzing the origin of glassy dynamics in supercooled liquids with a specific focus on the question of an underlying critical point, c) the collective behavior of active matter, which consists of individual entities that can produce and dissipate energy.Courses Taught
