Quasinormal Mode Oscillations in an Analogue Black Hole Experiment (2020)
Journal Article
Torres, T., Patrick, S., Richartz, M., & Weinfurtner, S. (2020). Quasinormal Mode Oscillations in an Analogue Black Hole Experiment. Physical Review Letters, 125(1), Article 011301. https://doi.org/10.1103/PhysRevLett.125.011301

The late stages of the relaxation process of a black hole are expected to depend only on its mass and angular momentum and not on the details of its formation process. Inspired by recent analogue gravity experiments, which demonstrate that certain bl... Read More about Quasinormal Mode Oscillations in an Analogue Black Hole Experiment.

Analog cosmology with two-fluid systems in a strong gradient magnetic field (2019)
Journal Article
Fifer, Z., Torres, T., Erne, S., Avgoustidis, A., Hill, R. J. A., & Weinfurtner, S. (2019). Analog cosmology with two-fluid systems in a strong gradient magnetic field. Physical Review E, 99(3), Article 031101(R). https://doi.org/10.1103/physreve.99.031101

We propose an experiment combining fluid dynamics and strong magnetic field physics to simulate cosmological scenarios. Our proposed system consists of two immiscible, weakly magnetized fluids moved through a strong gradient magnetic field. The diama...

On the observation of nonclassical excitations in Bose–Einstein condensates (2016)
Journal Article
Finke, A., Jain, P., & Weinfurtner, S. (2016). On the observation of nonclassical excitations in Bose–Einstein condensates. New Journal of Physics, 18(113017), https://doi.org/10.1088/1367-2630/18/11/113017

In the recent experimental and theoretical literature well-established nonclassicality criteria from the field of quantum optics have been directly applied to the case of excitations in matter-waves. Among these are violations of Cauchy–Schwarz inequ... Read More about On the observation of nonclassical excitations in Bose–Einstein condensates.

Extrinsic curvature in two-dimensional causal dynamical triangulation (2016)
Journal Article
Glaser, L., Sotiriou, T. P., & Weinfurtner, S. (2016). Extrinsic curvature in two-dimensional causal dynamical triangulation. Physical Review D, 94(6), Article 64014. https://doi.org/10.1103/PhysRevD.94.064014

Causal dynamical triangulation (CDT) is a nonperturbative quantization of general relativity. Hořava-Lifshitz gravity, on the other hand, modifies general relativity to allow for perturbative quantization. Past work has given rise to the speculation...
