DESCRIPTION:Speaker: Kartiek Agarwal\nhosted by Maksym Serbyn\nAbstract: We
  propose a new protocol for engineering quantum many-body Hamiltonians wit
 h enhanced symmetries. The protocol is based on repeated pulsed applicatio
 n of a set of unitary operators Xi\, with X2i=1\, (which can be generalize
 dto Xn=1\,n>2) in a self-similar-in-time ("polyfractal) manner. For local 
 initial Hamiltonians\, the protocol can simultaneously implement multiple 
 global and local symmetries\, with the accuracy improving superpolynomiall
 y with the fastest drive period. The effective Hamiltonian remains local a
 nd avoids heating over time scales that are stretched-exponentially long i
 n the drive frequency. Such Floquet engineering can be used to realize nov
 el non-equilibrium quantum phases. We also discuss how our protocol can be
  implemented robustly using a setup based on Majorana fermions. Networks o
 f such Majoranas can be used to implement novel symmetry-protected topolog
 ical phases\, lattice gauge theories\, among others.
