Probing Curved Spacetime Physics in Relativistic Materials – PROCURPHY

Submission summary

Quantum anomalies generated by fluctuations of quantum fields in curved spacetimes play a significant role in describing the inflationary period of our Universe and the exotic quantum processes that take place in the vicinity of black holes. These forefront problems of modern physics remain out-of-reach of current observational techniques. Our project is destined for the theoretical investigation of the quantum gravitational anomalies in condensed-matter environments aspiring to provide the solid ground for experimental exploration of these elusive quantum effects in laboratories. Indeed, it was understood very recently that gravitational anomalies could also reveal themselves in condensed matter physics by building on the subtle link between temperature variations and gravitational fields. Our program comprises several coherently interconnected pathways. We will explore the anomalous thermal properties of black holes using the heat-current noise in experimentally accessible quantum wires. We will also investigate curvature-induced anomalous thermal effects in relativistic three-dimensional Weyl and Dirac semimetals, focusing on nonlinear relations between the gravitational and thermal features. We will study the never-explored anomalous effects in the vicinity of vortices in superconductors and in the acoustic analog black holes in cold-atom condensates as both these systems possess a spatial region with a large superfluid velocity that resembles the near-horizon region of a real black hole. Finally, we will elucidate the experimentally traceable oscillations of the energy density in the dynamical Casimir effect where the gravitational anomaly opens an exciting prospect to implement a heating Floquet state.
