SUMMARY:Topological Effects of Quasiperiodic Driving
DESCRIPTION:Featuring David Long\, Boston University\nHosted by: Eric Boyer
	s\n\nPart of the Graduate Student Council Events.\n\nPart of the student se
	minar series. A recording of the talk will be posted on the event page.\n\n
	Abstract: Topology can underlie the quantization of observables in both sta
	tic and driven systems\, including quasiperiodically driven systems -- thos
	e driven by multiple incommensurate periodic tones. We derive a topological
	 classification of a class of quasiperiodically driven systems which we cal
	l anomalous localized topological phases (ALTPs). The classification depend
	s only on the sum of the spatial dimension and the number of incommensurate
	 tones\, a result we can understand intuitively through a formalism known a
	s the frequency lattice. Furthermore\, our classification allows us to iden
	tify a phase of one-dimensional two-tone-driven ALTPs which can act as a qu
	antized nonadiabatic energy pump between the two drives. We present explici
	t models in this phase\, with which we verify our predictions numerically.
