Query: Discontinuous Transitions Towards Vortex Condensates in Buoyancy-Driven
  Rotating Turbulence   Using direct numerical simulations of rotating Rayleigh-B\'enard convection,
we explore the transitions between turbulent states from a 3D flow state
towards a quasi-2D condensate known as the large-scale vortex (LSV). We vary
the Rayleigh number $Ra$ as control parameter and study the system response
(strength of the LSV) in terms of order parameters assessing the energetic
content in the flow and the upscale energy flux. By sensitively probing the
boundaries of the region of existence of the LSV in parameter space, we find
discontinuous transitions and we identify the presence of a hysteresis loop as
well as memoryless abrupt growth dynamics. We show furthermore that the
creation of the condensate state coincides with a discontinuous transition of
the energy transport into the largest mode of the system.
