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…
Quantum tribology: acceleration-induced Stokes friction and Magnus force in correlated Bose fluids
V. M. Kovalev, A. N. Osipov, I. G. Savenko
The Landau criterion, a cornerstone of quantum fluid dynamics, dictates that dissipation is forbidden for uniform motion below a critical velocity. Yet, the fundamental question of…
Josephson and Spin Currents in Coupled Polariton Condensates
A. Kudlis, I. Yu. Chestnov, A. N. Osipov +2
We analyze particle and spin currents in networks of coupled spinor exciton-polariton condensates arranged as plaquettes and regular polygonal rings. In closed geometries, spin-con…
Hidden chirality and half-vortex formation in exciton-polariton condensates
A. N. Osipov, I. Y. Chestnov, P. G. Lagoudakis +1
We show that a radially symmetric, nonresonantly pumped spinor exciton-polariton condensate can acquire chirality without a rotating drive, chiral geometry, or pump orbital angular…
Synchronization-induced flat bands in driven-dissipative dimer-waveguide chains
A. N. Osipov, I. G. Savenko, Sergej Flach +1
Flat bands in driven-dissipative systems offer a route to engineer strongly localized, long-lived excitations, yet their selective population via incoherent pumping remains an open…
Phase locking of ring-shaped exciton-polariton condensates to coherent optical drive
A. N. Osipov, S. V. Koniakhin, O. I. Utesov +2
The effect of an additional quasi-resonant drive on the dynamics of the ring-shaped incoherently pumped polariton condensates carrying angular momentum (vorticity) is studied theor…
