• Abstract: We report the experimental observation of vortex leapfrogging in a two-dimensional fluid of light. By imprinting two vortex-antivortex pairs and tracking their real-time evolution through phase-resolved imaging, we observe a dynamics that is accurately described by a point-vortex model with an outward background flow. By precisely controlling the initial vortex separation, we identify configurations in which leapfrogging breaks down and determine the corresponding dissipation mechanisms. The first originates from phase-slip events occurring at large injected velocities. The second arises when the injection of multi-charged vortices leads to the formation of a dispersive shock wave which acts as a continuous source of phase slippage. These mechanisms advance our understanding of vortex dynamics and dissipation in superfluids.

• Identifying Locally Turbulent Vortices within Instabilities [3.712362524473752]
  This work presents an approach for the automatic detection of locally turbulent vortices within turbulent 2D flows such as instabilites. Specifically, the enstrophy of the flow is simplified by topological persistence, and the vortices are extracted by collecting the basins of the simplified enstrophy's Morse complex. We introduce a set of indicators based on the kinetic energy power spectrum to estimate the correlation between the vortex's behavior and that of an idealized turbulent vortex.

  We demonstrate the controllable generation of distinct types of dispersive shock-waves emerging in a quantum droplet bearing environment. Surprisingly, dispersive shock waves persist across the hyperbolic-to-elliptic threshold. A plethora of additional wave patterns arise, such as rarefaction waves, traveling dispersive shock waves, (anti)kinks and droplet wavetrains.

  We investigate the Meissner currents of interacting bosons subjected to a staggered artificial gauge field in a three-leg ribbon geometry. The currents are uniform along each leg in the Meissner phase and form vortex-antivortex pairs in the vortex phase.

  We use intuition to predict the formation of non-trivial photonic steady-states in one and two dimensions. We show that subradiant emitter configurations are linked to the emergence of steady-state light-localization in the driven-dissipative setting. These results shed light on the recently reported optically-defined cavities in polaritonic lattices.

  In spite of particle losses the quantum entanglement propagation exhibits a ballistic character with propagation speeds related to the differerent quasiparticles that are involved in the dynamics. Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.
