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…
Symmetries and Conservation Laws in Quantum Trajectories: Dissipative Freezing
Carlos Sánchez Muñoz, Berislav Buca, Joseph Tindall +3
In driven-dissipative systems, the presence of a strong symmetry guarantees the existence of several steady states belonging to different symmetry sectors. Here we show that, when…
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…
Heating-Induced Long-Range -Pairing in the Hubbard Model
Joseph Tindall, Berislav Buca, Jonathan R. Coulthard +1
We show how, upon heating the spin degrees of freedom of the Hubbard model to infinite temperature, the symmetries of the system allow the creation of steady-states with long-range…
Non-stationary coherent quantum many-body dynamics through dissipation
Berislav Buca, Joseph Tindall, Dieter Jaksch
The assumption that quantum systems relax to a stationary state in the long-time limit underpins statistical physics and much of our intuitive understanding of scientific phenomena…
