SUMMARY:Boosted one-dimensional superfluids on a lattice
DESCRIPTION:Featuring Sayonee Ray\, University of New Mexico\, CQuIC\nHoste
	d by: Christopher Laumann\n\nPart of the Condensed Matter Theory Seminar Se
	ries.\n\nWe study the effect of a boost (Fermi sea displaced by a finite mo
	mentum) on one dimensional systems of lattice fermions with short-ranged in
	teractions. In the absence of a boost such systems with attractive interact
	ions possess algebraic superconducting order. Motivated by physics in highe
	r dimensions\, one might naively expect a boost to weaken and ultimately de
	stroy superconductivity. However\, we show that for one dimensional systems
	 the effect of the boost can be to strengthen the algebraic superconducting
	 order by making correlation functions fall off more slowly with distance. 
	This phenomenon can manifest in interesting ways\, for example\, a boost ca
	n produce a Luther-Emery phase in a system with both charge and spin gaps b
	y engendering the destruction of the former.\n\nAUTHORS: Sayonee Ray\, Subr
