T-DO Conference Room (TA-03, Bldg 123)
Speaker: Adolfo del Campo (University of Massachusetts, Boston)
Technical Host: Wojciech Zurek
TOPIC: Rhapsody on a theme of Kibble and Zurek
Abstract
Across a continuous phase transition, the relaxation time diverges and the breakdown of adiabaticty is unavoidable. In such scenario, the Kibble-Zurek mechanism (KZM) describes the dynamics of symmetry breaking. KZM dictates that density of excitations scales as a universal power-law of the quench time, and slow driving is needed to approach the adiabatic limit. I shall report recent results concerning the universal dynamics across quantum phase transitions. In particular, I shall report the recent experimental test of KZM in the transverse-field quantum Ising chain using a quantum simulator [1] and the emergence of noise-induced anti-Kibble-Zurek behavior [2].
