Multistable circular currents of polariton condensates trapped in ring potentials
Franziska Barkhausen, Stefan Schumacher, Xuekai Ma
We demonstrate the formation and trapping of different stationary solutions, oscillatory solutions, and rotating solutions of a polariton condensate in a planar semiconductor micro…
Controllable high-speed polariton waves in a PT-symmetric lattice
Xuekai Ma, Yaroslav Y. Kartashov, Tingge Gao +1
Parity-time (PT) symmetry gives rise to unusual phenomena in many physical systems, presently attracting a lot of attention. One essential and non-trivial task is the fabrication a…
Realization of all-optical vortex switching in exciton-polariton condensates
Xuekai Ma, Bernd Berger, Marc Assmann +5
Vortices are topological objects representing the circular motion of a fluid. With their additional degree of freedom, the 'vorticity', they have been widely investigated in many p…
Circular polarization reversal of half-vortex cores in polariton condensates
Matthias Pukrop, Stefan Schumacher, Xuekai Ma
Vortices are topological objects carrying quantized orbital angular momentum and have been widely studied in many physical systems for their applicability in information storage an…
Split-ring polariton condensates as macroscopic two-level quantum systems
Yan Xue, Igor Chestnov, Evgeny Sedov +5
Superposition states of circular currents of exciton-polaritons mimic the superconducting flux qubits. The phase of a polariton fluid must change by an integer number of , when…
