Emergence of Isotropy and Dynamic Scaling in 2D Wave Turbulence in a Homogeneous Bose Gas.

| Description | This grant had been extended due to covid-related delays, but in the end was very successful and has already resulted in 5 major publications - 1 Nature, 1 Science, 1 Nature Physics, and 2 Phys. Rev. Letters; a few more papers are currently under review or in draft stage. In our Science paper (2019) we have demonstrated a novel way to study turbulence, which is a centuries-old problem, using homogeneous ultracold atomic gases, and in a complementary PRL (2021) we have studied the nonlinear decay of the lowest gapped mode of a Bose-Einstein condensate, which is a first step towards the microscopic understanding of the generation of turbulence. In a 2021 Nature Physics we observed universal dynamical scaling behaviour in the thermalisation dynamics of a closed quantum system. In our theoretical PRL paper (highlighted as an Editors' Suggestion) we have shown how, counterintuitively, in some cases dissipative processes can lead to purification of quantum states. In the final stages of the grant we also studied first and second sound in hydrodynamic homogeneous Bose gases, a particular highlight being our first ever observation (in any physical system) of the first and second sound in a two-dimensional superfluid; this work was published in Nature in 2021. |
| Exploitation Route | We have studied turbulence in a rather academic blue-sky setting, but this ubiquitous phenomenon is also relevant in many practical contexts, from engineering to chemical industry, and the better understanding of its fundamental principle could in the long run have significant economic and societal impacts. Our work on dissipation-driven purification of quantum states could be relevant for preparation of practically important states in the context of the emerging quantum technologies. |

| Description | Our work within this grant was instrumental for brining €2.5M into the UK via an ERC Advanced grant. Within the UK, our work on nonequilibrium physics was crucial for establishing a new research area that combines EPSRC and STFC research, and fundamental research with quantum technologies. Part of this impact (for us) is the further funding we got from STFC, but the bigger and longer-lasting impact is the (contribution to) formation of a new multi-disciplinary community in the UK that is training a large future highly-skilled workforce. |
