SUMMARY:One-electron spectral properties of one-dimensional metallic states
	 in MoSe(2) line defects and in Bi/InSb(001)
DESCRIPTION:Featuring Jose M.P. Carmelo\nHosted by: David Campbell\n\nPart 
	of the Biophysics/Condensed Matter Seminar Series.\n\nTwin grain boundaries
	 in monolayers of transition metal dichalcogenides such as molybdenum disel
	enide [MoSe(2)] and self-assembled atomic structures on the surface of semi
	conductors such as a bismuth-induced anisotropic structure on indium antimo
	nide [Bi/InSb(001)] are exceptional candidates for truly one-dimensional me
	tals in their high temperature phases. The microscopic mechanisms behind th
	eir exotic spectral properties involve long-range interactions of electrons
	 confined to one-dimensional channels. We extend the universal theory for t
	he finite-energy spectral properties of a wide class of one-dimensional cor
	related lattice systems whose microscopic mechanisms involve phase shifts i
	mposed by a mobile quantum impurity on the electronic lattice systems with 
	long-range interactions. In contrast to standard theoretical schemes (such 
	as TLL theory) that do not account for the effects of long-range interactio
	ns\, our theoretical predictions agree quantitatively with the observed one
	-electron spectral properties of one-dimensional metallic states in MoSe(2)
	 line defects and in Bi/InSb(001).
