Stationary State Degeneracy of Open Quantum Systems with Non-Abelian Symmetries
Zhao Zhang, Joseph Tindall, Jordi Mur-Petit +2
We study the null space degeneracy of open quantum systems with multiple non-Abelian, strong symmetries. By decomposing the Hilbert space representation of these symmetries into an…

Quantum Synchronisation Enabled by Dynamical Symmetries and Dissipation
Joseph Tindall, Carlos Sánchez Muñoz, Berislav Buča +1
In nature, instances of synchronisation abound across a diverse range of environments. In the quantum regime, however, synchronisation is typically observed by identifying an appro…

Non-stationary dynamics and dissipative freezing in squeezed superradiance
Carlos Sánchez Muñoz, Berislav Buča, Joseph Tindall +3
In this work, we study the driven-dissipative dynamics of a coherently-driven spin ensemble with a squeezed, superradiant decay. This decay consists of a sum of both raising and lo…
