SUMMARY:Many body localisation with weak disorder in the quantum east model
DESCRIPTION:Featuring Philip Crowley\n\nPart of the Condensed Matter Theory
	 Seminar Series.\n\nThe quantum dynamics of closed many body systems has re
	ceived renewed attention with growing experimental capability to realise th
	ese systems. Of particular interest is progress which has established the M
	any-Body Localised phase as a robust state of matter. These non-thermalizin
	g systems present intriguing dynamics and show quantum systems to be capabl
	e of violating the fundamental underlying assumptions of classical statisti
	cal mechanics. Generally this is understood to be a disorder driven transit
	ion\, however the possibility of a many-body localised phase in the absence
	 of static disorder remains an interesting prospect.\n \nWe study a kinetic
	ally constrained spin model which displays evidence for a disorder-free loc
	alisation transition and characterise the different phases of the system by
	 their response to the introduction of static disorder. We find evidence of
	 the existence of a localisation transition for arbitrarily weak disorder a
	t sufficiently low temperatures. This weakly localising phase links the mor
	e intensely studied disordered fully localised phase to the disorder free l
	imit. We extract the local integrals of motion\, characteristic of the diso
	rdered localised phase\, and study their fate in the limit of weak disorder
	. These results connect our understanding of the disordered and disorder fr
	ee localisation transitions.
