SUMMARY:Transverse Chiral Optical Forces by Surface Plasmon Polaritons
DESCRIPTION:Featuring Hossein Alizadeh\n\nPart of the Departmental Seminars
	.\n\n![Hossein](/resources/event-image/1463/6abd753_small)\n\nDissertation 
	Committee: Bjoern Reinhard\, Shyam Erramilli\, Roberto Paiella\, Kevin Blac
	k\, Raj Mohanty.\n\nAbstract:\n\nRecently the new concepts of transverse sp
	in angular momentum and Belinfante spin momentum of evanescent waves have d
	rawn considerable attention. Here\, we investigate these novel physical pro
	perties of electromagnetic fields in the context of locally excited surface
	 plasmon polaritons. We demonstrate\, both analytically and numerically\, t
	hat locally excited surface plasmon polaritons possess transverse spin angu
	lar momentum and Belinfante momentum with rich and non-trivial characterist
	ics. We also show that the transverse spin angular momentum of locally exci
	ted surface plasmon polaritons leads to the emergence of transverse chiral 
	forces in opposite directions for chiral objects of different handedness. T
	he magnitude of such a transverse force is comparable to the optical gradie
	nt force and scattering forces. This finding may pave the way for realizati
	on of optical separation of chiral biomolecules
