SUMMARY:Spin-gapped phases in nanowires 
DESCRIPTION:Featuring Tommy Li\, Niels Bohr Institute Copenhagen\nHosted by
	: Julian Ingham\n\nPart of the Condensed Matter Theory Seminar Series.\n\nO
	ne dimensional fermionic models with gapped collective spin modes have been
	 studied theoretically for decades\, but their physical realization in semi
	conductor systems has remained elusive. These phases exhibit intriguing phy
	sical properties more reminiscent of superconductors than ordinary metals. 
	I will propose some simple physical setups in semiconductor nanowires in wh
	ich spin-gapped phases appear naturally due to the interplay between the or
	bital physics of the wire and the three-dimensional Coulomb interaction\, a
	nd are protected by the spatial symmetries of the wire. I will also discuss
	 phases occurring in multiband systems which exhibit topological properties
	 and host Majorana edge modes.
