Symmetries and correlations in continuous time crystals

A Mukherjee, Y Ibrahim, M Hajdušek, S Vinjanampathy - Physical Review A, 2024 - APS
We demonstrate the inadequacy of mean-field theory by exploring the effects of initial-state
correlations on the dynamics of continuous time crystals, motivating the need for higher …

Uniformly decaying subspaces for error-mitigated quantum computation

N Suri, J Saied, D Venturelli - Physical Review A, 2024 - APS
We present a general condition to obtain subspaces that decay uniformly in a system
governed by the Lindblad master equation and use them to perform error-mitigated quantum …

Qualitatively altered driven Dicke superradiance in extended systems due to infinitesimal perturbations

W Tong, F Robicheaux - Physical Review A, 2024 - APS
The driven Dicke model, with interesting quantum phases induced by parametrized driving,
has been intensively studied in cavities, where permutation symmetry applies due to the …

Exotic synchronization in continuous time crystals outside the symmetric subspace

P Solanki, M Krishna, M Hajdušek, C Bruder… - arXiv preprint arXiv …, 2024 - arxiv.org
Exploring continuous time crystals (CTCs) within the symmetric subspace of spin systems
has been a subject of intensive research in recent times. Thus far, the stability of the time …
