Operator space transport in collective spin Lindbladians
Dominik Nemeth, Ahsan Nazir, Robert-Jan Slager +1
Boundary time crystals (BTCs) are paradigmatic examples of continuous time crystals that emerge in collective, dissipative quantum systems. Their microscopic origin, however, remai…

Topological Boundary Time Crystal Oscillations
Dominik Nemeth, Ahsan Nazir, Alessandro Principi +1
Boundary time crystals (BTCs) break time-translation symmetry and exhibit long-lived, robust oscillations insensitive to initial conditions. We show that collective spin BTCs can a…

Analytical solution of boundary time crystals via the superspin basis
Dominik Nemeth, Alessandro Principi, Ahsan Nazir
Boundary time crystals (BTCs) in dissipative collective spin systems have been extensively studied using numerical, mean-field, and perturbative approaches. However, an explicit Li…
