Quantum scarring in a spin-boson system: fundamental families of periodic orbits
Saúl Pilatowsky-Cameo, David Villaseñor, Miguel A. Bastarrachea-Magnani +3
As the name indicates, a periodic orbit is a solution for a dynamical system that repeats itself in time. In the regular regime, periodic orbits are stable, while in the chaotic re…
Ubiquitous quantum scarring does not prevent ergodicity
Saúl Pilatowsky-Cameo, David Villaseñor, Miguel A. Bastarrachea-Magnani +3
In a classically chaotic system that is ergodic, any trajectory will be arbitrarily close to any point of the available phase space after a long time, filling it uniformly. Using B…
Attractive and repulsive exciton-polariton interactions mediated by an electron gas
M. A. Bastarrachea-Magnani, A. Camacho-Guardian, G. M. Bruun
Realising strong photon-photon interactions in a solid-state setting is a major goal with far reaching potential for optoelectronic applications. Using Landau's quasiparticle frame…
Mediated interactions and photon bound states in an exciton-polariton mixture
A. Camacho-Guardian, M. Bastarrachea-Magnani, G. M. Bruun
The quest to realise strongly interacting photons remains an outstanding challenge both for fundamental science and for applications. Here, we explore mediated photon-photon intera…
Spectral Structure and Many-Body Dynamics of Ultracold Bosons in a Double-Well
Frank Schäfer, Miguel A. Bastarrachea-Magnani, Axel U. J. Lode +2
We examine the spectral structure and many-body dynamics of two and three repulsively interacting bosons trapped in a one-dimensional double-well, for variable barrier height, inte…
Quantum vs classical dynamics in a spin-boson system: manifestations of spectral correlations and scarring
D Villasenor, S Pilatowsky-Cameo, M A Bastarrachea-Magnani +3
We compare the entire classical and quantum evolutions of the Dicke model in its regular and chaotic domains. This is a paradigmatic interacting spin-boson model of great experimen…
