| Description: | [DPS Seminar] Kumar Abhinav (DPS, IISER Kolkata) -- Excitonic spin control with Topological origin |
| Date: | Wednesday, Aug 26, 2015 |
| Time: | 11:30 a.m. - 1 p.m. |
| Venue: | G02, Lecture Hall Complex |
| Details: | It is demonstrated that planar relativistic systems can support a novel excitonic bound state of topological origin, stable against quantum and thermal fluctuations. Physical systems of graphitic nature hosting multiple Dirac fermion species are suitable for realizing such quasi-particles under certain conditions. Dynamics of these charge-less, spin-one states can be controlled by external fields, with induced chemical potential. |
