Quasinormal modes are a set of damped resonances that describe how an excited open system is driven back to equilibrium. In gravitational physics these modes characterize the ringdown of a perturbed black hole, e.g., following a binary black hole mer...

Towards the cold atom analog false vacuum (2018)
Journal Article
Braden, J., Johnson, M. C., Peiris, H. V., & Weinfurtner, S. (2018). Towards the cold atom analog false vacuum. Journal of High Energy Physics, 2018(7), https://doi.org/10.1007/jhep07%282018%29014

Analog condensed matter systems present an exciting opportunity to simulate early Universe models in table-top experiments. We consider a recent proposal for an analog condensed matter experiment to simulate the relativistic quantum decay of the fals... Read More about Towards the cold atom analog false vacuum.

Low-frequency analogue Hawking radiation: The Bogoliubov-de Gennes model (2018)
Journal Article

We analytically study the low-frequency properties of the analogue Hawking effect in Bose-Einstein condensates. We show that in one-dimensional flows displaying an analogue horizon, the Hawking effect is dominant in the low-frequency regime. This hap...

Low-frequency analogue Hawking radiation: the Korteweg–de Vries model (2018)
Journal Article

We derive analytic expressions for the low-frequency properties of the analogue Hawking radiation in a general weak-dispersive medium. A thermal low-frequency part of the spectrum is expected even when dispersive effects become significant. We consid...
