| Description: | [DPS Seminar] Prof. Sumathi Rao (HRI Allahabad) -- Spin mode switching in the quantum Hall effect |
| Date: | Wednesday, Nov 01, 2017 |
| Time: | 12:30 p.m. - 1:30 p.m. |
| Venue: | G02, Lecture Hall Complex |
| Details: | Along with a brief introduction to the phenomenon of the integer quantum Hall effect, I will briefly review edge reconstruction due to Coulomb interactions and changes in the smoothness of the edge potential. Then I will describe some recent work where we show how exchange interactions can cause a switching of the spin of the edge modes, causing like spins to come close to each other. |
