Thresholdless corner vortex solitons in fractal Sierpiński topological insulators
Yiqi Zhang, Alexander V. Kireev, Victor O. Kompanets +12
Quantized vortices are ubiquitous in physics, spanning superconductivity, astrophysics, superfluid condensed matter systems, and nonlinear optics. Yet embedding vorticity into topo…
Observation of an aperiodic polariton monotile
Sergey Alyatkin, Yaroslav V. Kartashov, Kirill Sitnik +2
A plethora of unconventional localization phenomena and fractal features of linear spectrum observed in quasiperiodic structures have been accompanied by a long-standing quest for…
Coherence Revivals and Lifetime Extension of Polariton Condensates by Mirror-Mediated Self-Feedback
I. Smirnov, S. Alyatkin, P. G. Lagoudakis
Temporal coherence of driven-dissipative condensates is limited by phase noise. We show that mirror-mediated time-delayed self-feedback enables control of coherence in a trapped ex…
Observation of topological vortex solitons on disclinations
A. V. Kireev, K. Sabour, V. O. Kompanets +13
Vortex-carrying wave fields play a crucial role in photonics due to unusual propagation properties and interactions with matter, which enable numerous practical applications rangin…
Single-Shot Flow Spectroscopy of a Polariton Condensate: Kibble-Zurek and Kolmogorov-Like Scaling
Ivan Krasionov, Anton Putintsev, Maksim Kolker +3
Quantized vortices are fundamental topological excitations of quantum fluids. We report single-shot interferometric measurements of spontaneous vortex nucleation in a room-temperat…
