SUMMARY:Finite-depth quantum circuits and many-body localization
DESCRIPTION:Featuring Arijeet Pal \, UCL\nHosted by: Christopher Laumann\n\
	nPart of the Biophysics/Condensed Matter Seminar Series.\n\nDynamics of dis
	ordered\, quantum many-body systems provide a classic physical setting for 
	the breakdown of quantum ergodicity\, known as many-body localization (MBL)
	. In this novel out of equilibrium quantum phase\, the many-body system act
	s as a local memory even in highly excited states which is characterized by
	 an emergent integrability. Utilizing the local conservation laws I will pr
	esent an efficient representation of unitary circuits approximating the ful
	l spectrum of MBL eigenstates.\n\nI will show how the approximating circuit
	 can be used to construct the algebra of all the exact l-bit operators and 
	probe their behaviour close to the MBL-thermal transition in one dimension.
	 Furthermore\, the circuit can be generalized to two dimensions to estimate
	 the location of the "MBL transition" in the Bose-Hubbard model which was p
	utatively observed in recent cold atomic experiments.
