SUMMARY:"Status of the Search for Majorana Fermions in Semiconductor Nanowi
	res"
DESCRIPTION:Featuring Sergey Frolov\, University of Pittsburgh\nHosted by: 
	Alexander Sushkov\n\nPart of the Condensed Matter Theory Seminar Series.\n\
	nTunneling spectroscopy measurements on one-dimensional superconducting hyb
	rid materials have revealed signatures of Majorana fermions which are the e
	dge states of a bulk topological superconducting phase. We couple strong sp
	in-orbit semiconductor InSb nanowires to conventional superconductors (NbTi
	N\, Al) to obtain additional signatures of Majorana fermions and to explore
	 the  topological phase transition. A potent alternative explanation for ma
	ny of the recent experimental Majorana reports is that a non-topological An
	dreev state localizes near the end of a nanowire. We compare Andreev and Ma
	jorana modes and investigate ways to clearly distinguish the two phenomena.
	 We are also exploring how Andreev states can be chained together along the
	 nanowire to realize the one-dimensional Kitaev model\, a discrete way of g
	enerating Majorana modes.
