SUMMARY:Constructing Ultra-Slow Glasses in Lattice Models for Reversible Co
	mputing
DESCRIPTION:Featuring Lei Zhang\n\nPart of the Preliminary Oral Exam.\n\nEx
	amining Committee:  Andrei Ruckenstein\, Claudio Chamon\, Michael El-Batano
	uny\, Richard Brower\n\nAbstract:\n\nWe construct a two-dimensional lattice
	 model that lacks any finite temperature phase transition and yet displays 
	relaxation times that grow as a double exponential of the inverse temperatu
	re. The model has bulk translational invariance\, only broken by the presen
	ce of the boundaries. The lattice model is associated to a reversible circu
	it that can multiply or factorize integers\, depending on the boundary cond
	itions. When the lattice model reaches its ground state\, all computations 
	are performed without error. The ultra-slow (double exponential in inverse 
	temperature) glassy dynamics is associated with the difficulty of the syste
	m to heal computational errors that cost little energy but flip a volumetri
	c number of bits in the system.\n\n![Lei](/resources/event-image/1826/af5ae
