Latent Su-Schrieffer-Heeger models
Malte Röntgen, Xuelong Chen, Wenlong Gao +5
The Su-Schrieffer-Heeger (SSH) chain is the reference model of a one-dimensional topological insulator. Its topological nature can be explained by the quantization of the Zak phase…
Detecting Rotational Superradiance in Fluid Laboratories
Vitor Cardoso, Antonin Coutant, Mauricio Richartz +1
Rotational superradiance was predicted theoretically decades ago, and is chiefly responsible for a number of important effects and phenomenology in black-hole physics. However, rot…
Stability properties of Hawking radiation in the presence of ultraviolet violation of local Lorentz invariance
Antonin Coutant
In this thesis, we study several features of Hawking radiation in the presence of ultraviolet Lorentz violations. These violations are implemented by a modified dispersion relation…
Unitary and non-unitary transitions around a cosmological bounce
Antonin Coutant
In this work, we investigate the notion of time and unitarity in the vicinity of a bounce in quantum cosmology, that is, a turning point for the scale factor. Because WKB methods d…
Hawking radiation of massive modes and undulations
Antonin Coutant, Alessandro Fabbri, Renaud Parentani +2
We compute the analogue Hawking radiation for modes which posses a small wave vector perpendicular to the horizon. For low frequencies, the resulting mass term induces a total refl…
