Detecting the Unruh Effect in Thermal Analogue Systems

Explore the detection of the Unruh effect in thermal analogue systems through this 16-minute conference talk from the Workshop on "Blackbody Radiation Induced Effects and Phenomena" at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the mathematical equivalence between quantum fields in curved spacetimes and wave fluctuations in inviscid fluids, as discovered by Unruh in 1981. Examine recent proposals for experimental analogue gravity systems to detect the analogue Unruh effect, focusing on Bose-Einstein Condensates (BECs) and superfluid helium (He-II) operating at extremely low temperatures. Gain insights into the newly developed theory that considers non-zero background temperature, bridging the gap between theoretical concepts and realizable experiments. Cover key topics including analog gravity, BEC, quantum field theory, and superfluid helium to understand the complexities of detecting thermality due to acceleration in these systems.
