Third sound detectors in accelerated motion (2024)
Journal Article
Bunney, C. R. D., Barroso, V. S., Biermann, S., Geelmuyden, A., Gooding, C., Ithier, G., Rojas, X., Louko, J., & Weinfurtner, S. (2024). Third sound detectors in accelerated motion. New Journal of Physics, 26, Article 065001. https://doi.org/10.1088/1367-2630/ad5758

An accelerated observer moving through empty space sees particles appearing and disappearing, while an observer with a constant velocity does not register any particles. This phenomenon, generally known as the Unruh effect, relies on an initial vacuu... Read More about Third sound detectors in accelerated motion.

Interferometric Unruh Detectors for Bose-Einstein Condensates (2020)
Journal Article
Gooding, C., Biermann, S., Erne, S., Louko, J., Unruh, W. G., Schmiedmayer, J., & Weinfurtner, S. (2020). Interferometric Unruh Detectors for Bose-Einstein Condensates. Physical Review Letters, 125(21), Article 213603. https://doi.org/10.1103/PhysRevLett.125.213603

The Unruh effect predicts a thermal response for an accelerated detector moving through the vacuum. Here we propose an interferometric scheme to observe an analogue of the circular Unruh effect using a localized laser coupled to a Bose-Einstein conde...

Unruh and analogue Unruh temperatures for circular motion in 3+1 and 2+1 dimensions (2020)
Journal Article
Biermann, S., Erne, S., Gooding, C., Louko, J., Schmiedmayer, J., Unruh, W. G., & Weinfurtner, S. (2020). Unruh and analogue Unruh temperatures for circular motion in 3+1 and 2+1 dimensions. Physical Review D, 102(8), Article 085006. https://doi.org/10.1103/PhysRevD.102.085006

The Unruh effect states that a uniformly linearly accelerated observer with proper acceleration a experiences Minkowski vacuum as a thermal state in the temperature Tlin=a/(2π), operationally measurable via the detailed balance condition between exci...
