Big time crystals: a new paradigm in condensed matter. This project aims to extend condensed matter physics to the time dimension using big time crystals created by a periodically driven Bose-Einstein condensate. Such a system is expected to offer exceptional versatility, allowing effective potentials and long-range interactions in a time lattice to be engineered almost at will by proper periodic driving and modulation of the particle interaction. Expected outcomes include realisation of novel c ....Big time crystals: a new paradigm in condensed matter. This project aims to extend condensed matter physics to the time dimension using big time crystals created by a periodically driven Bose-Einstein condensate. Such a system is expected to offer exceptional versatility, allowing effective potentials and long-range interactions in a time lattice to be engineered almost at will by proper periodic driving and modulation of the particle interaction. Expected outcomes include realisation of novel condensed matter phenomena such as topologically protected states in the time dimension, time crystalline structures exhibiting disorder or quasi-crystalline order and time-tronics devices analogous to electronics. Potential future benefits include novel advanced materials and semiconductor-like devices. Read moreRead less
Hydrodynamics of quantum fluids. Since the 19th century, the governing equations of classical fluid dynamics or hydrodynamics have been an indispensable tool for transformative applications in aeronautics, medicine, and climate science. However, the applicability of hydrodynamics to the realm of quantum matter and quantum fluids is not well understood. This project intends to fill in this knowledge gap by developing new hydrodynamic theories of quantum fluids formed by ultracold quantum gases. T ....Hydrodynamics of quantum fluids. Since the 19th century, the governing equations of classical fluid dynamics or hydrodynamics have been an indispensable tool for transformative applications in aeronautics, medicine, and climate science. However, the applicability of hydrodynamics to the realm of quantum matter and quantum fluids is not well understood. This project intends to fill in this knowledge gap by developing new hydrodynamic theories of quantum fluids formed by ultracold quantum gases. The expected outcomes are the knowledge and theoretical tools required to underpin Australia’s advances in quantum technology applications, such as the design of quantum heat engines, control of heat transport in quantum nanowires, and fabrication of new energy efficient materials.Read moreRead less
