Global Satellite Session - Brazil: ICTP-SAIFR Session on Quantum Technologies

Hydrodynamic instabilities in classical fluids, often characterized by the exponential growth of a well-defined pattern, are encountered in many mundane situations. Increasing our understanding of the underlying mechanisms of such instabilities has a strong impact in modeling fluid dynamics in a broad scenario and in fundamental problems such as the transition from laminar to turbulent flow. In the context of quantum fluids, quantum hydrodynamic instabilities (QHI) are related to the superfluid properties of these systems offering a new approach when studying superfluidity [1,2]. Thanks to their high degree of control and simple detection techniques, ultracold atomic gases are ideal platforms to engender and observe such QHI. In this work, we present the current status of the construction of a new experimental setup capable of addressing the specific conditions for the onset of different hydrodynamic instabilities in a 2D Bose gas.
