|Talk Title: Inflation Dynamics of quantum phase transition in a driven Bose-Einstein condensate
Talk Place: M-234
Talk Time: 21-Dec-2017 3:00 pm
Quantum phase transitions are transitions between distinct many-body ground states, and are of extensive interest in research ranging from condensed matter physics to cosmology. Key features of the phase transitions include a stage with rapid growth of new order parameter, called inflation in cosmology, followed by the formation of topological defects. Based on Bose-Einstein condensates of cesium atoms in a shaken lattice, we report the observation of Kibble-Zurek scaling of quantum critical dynamics , and inflationary dynamics across the quantum critical point . In particular, the inflation manifests in the exponential growth and high harmonic generations of populations in well-resolved momentum states .
