Abstract:

Excitons in coupled quantum wells are optically active quasiparticles that can be manipulated to produce a range of logic devices that support both optical and electrical input/output. Exciton interaction properties and potential landscapes can be customized making them useful as a model system for emulation of other quantum systems (analog quantum computing). Integer spin of excitons means they obey Bose statistics and can form condensed states with long range spatial coherence and long spin lifetime. Electrostatic lattices for excitons are a first step towards emulation of electron behavior in a crystal potential. Tunable electrostatic lattices for excitons have been demonstrated in one and two dimensions. I will present an overview of recent work on excitonic devices and studies of exciton transport in tunable lattice potentials.

Dr. Mikas Remeika received his BS from University of Illinois at Urbana-Champaign, working with Prof. Alexey Bezryadin on superconductivity in quasi 1-dimensional wires. He continued to work on low temperature physics during MS and PhD studies at University of California San Diego with Prof. Leonid Butov, using optical probes to study transport and coherence of excitons in 2 dimensional heterostructures. He received his PhD degree in 2013 and is currently working at Intel corporation semiconductor technology development center in Oregon, USA.
