[institut] SCL seminar: Marko Grujic, Thursday, 9 July, 14:00

[Antun Balaz]

Dear colleagues,

You are cordially invited to the Scientific Computing Laboratory seminar, which will be held on Thursday, 9 July 2015 at 14:00 in the library reading room of the Institute of Physics Belgrade. The talk entitled

Chiral properties of topological-state loops

will be given by Dr. Marko Grujić (School of Electrical Engineering, University of Belgrade). Abstract of the talk:

The angular momentum quantization of chiral gapless modes confined to a circularly shaped interface between two different topological phases will be investigated. By examining several different setups, we show analytically that the angular momentum of the topological modes exhibits a highly chiral behavior, and can be coupled to spin and/or valley degrees of freedom, reflecting the nature of the interface states. A simple general one-dimensional model, valid for arbitrarily shaped loops, will be shown to predict the corresponding energies and the magnetic
moments. These loops can be viewed as building blocks for artificial magnets with tunable and highly diverse properties.

Best regards,
Antun Balaž
