Host: Atilla Erçelebi
ABSTRACT — Aharonov-Bohm effect is connected by direct influence of the vector potential on phase of wavefunction of a charged particle. In the domain of mesoscopic transport its consequence is appearance of the oscillations of conductance of mesoscopic rings in both ballistic and diffusive regime. Fundamantally, the phenomenon is a consequence of the breaking of time- reversion symmetry and is one of the manifestations of the geometric phase. In our talk we will consider two novel analogues of the Aharonov- Bohm effect. We will consider the oscillations in mesoscopic conductance induced by circular polarized light and polariton interferometer on geometric phase.
