  • The turbulent dynamics of a 2D quantum fluid of exciton–polaritons is measured in a planar AlGaAs microcavity after a pulsed optical excitation. Clear evidence of both the onset of vortex clustering and inverse energy cascade is provided.

  • Using a patterned waveguide, a Bose–Einstein condensate of polaritons is realized in a bound state in the continuum, with a low condensation threshold density that occurs at a dispersion saddle point.

  • Phases of matter are characterized by order parameters describing the type and degree of order in a system. Here, the authors explore the magnetic phases and the phase transitions present in a near-zero temperature spin-1 spin-orbit-coupled Bose gas, observing ferromagnetic and unpolarized states.

  • Here, the authors study topology in spin-orbit coupled 87Rb atoms by using time domain spectroscopy and quantum state tomography. They measure full quantum state to extract the Berry phase of the system and show signatures of a half-integer Chern index.

  • The evolution of many-body magnetic spin systems is influenced by many factors, including inhomogeneity and the presence of interfaces. These effects have now been measured in a far-from-equilibrium binary mixture of ultracold gases.
