Topological charge switching in trapped polariton condensates
Jaewon Kim, Hyun Gyu Song, Daegwang Choi +1
Topological charges in photonic systems provide a robust degree of freedom with direct applications in optical information processing. Bound states in the continuum (BICs) in photo…

Subcritical bifurcation and on-off bistability in ballistic polariton condensates
Oleg I. Utesov, Soohong Choi, Pavel Kozhevin +11
Dynamics of exciton-polariton condensates under continuous-wave incoherent Gaussian optical pumping is considered. It is shown that the conventional supercritical Stuart-Landau pic…

Observation of a partially rotating superfluid of exciton-polariton
Daegwang Choi, Min Park, Byoung Yong Oh +6
Rotation of a container holding a viscous fluid forms a vortex which grows with increasing angular velocity. A superfluid, however, is intrinsically different from these normal flu…
