Universality in Non-Equilibrium Quantum Systems
William Berdanier
The phenomenon of universality is one of the most striking in many-body physics. Despite having sometimes wildly different microscopic constituents, systems can nonetheless behave…
Energy drag in particle-hole symmetric systems as a quantum quench
William Berdanier, Thomas Scaffidi, Joel E. Moore
Two conducting quantum systems coupled only via interactions can exhibit the phenomenon of Coulomb drag, in which a current passed through one layer can pull a current along in the…
Universal Dynamics of Stochastically Driven Quantum Impurities
William Berdanier, Jamir Marino, Ehud Altman
We show that the dynamics of a quantum impurity subject to a stochastic drive on one side and coupled to a quantum critical system on the other display a universal behavior inherit…
Strong-Disorder Renormalization Group for Periodically Driven Systems
William Berdanier, Michael Kolodrubetz, S. A. Parameswaran +1
Quenched randomness can lead to robust non-equilibrium phases of matter in periodically driven (Floquet) systems. Analyzing transitions between such dynamical phases requires a met…
Floquet Quantum Criticality
William Berdanier, Michael Kolodrubetz, S. A. Parameswaran +1
We study transitions between distinct phases of one-dimensional periodically driven (Floquet) systems. We argue that these are generically controlled by infinite-randomness fixed p…
Floquet Dynamics of Boundary-Driven Systems at Criticality
William Berdanier, Michael Kolodrubetz, Romain Vasseur +1
A quantum critical system described at low energy by a conformal field theory (CFT) and subjected to a time-periodic boundary drive displays multiple dynamical regimes depending on…
Intense Ion Beam Neutralization Using Underdense Background Plasma
William Berdanier, Prabir K. Roy, Igor Kaganovich
Producing a dense background plasma for neutralization purposes is experimentally difficult and requires a large amount of energy. We show that even an underdense background plasma…
