Operator Space Transport and the Emergence of Boundary Time Crystals
Dominik Nemeth, Ahsan Nazir, Robert-Jan Slager +1
Boundary time crystals (BTCs) are prominent examples of continuous time crystals in collective spin systems governed by Lindbladian evolution. To date, their analysis has mostly re…
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…
Dicke Superradiance in Extended 2D Quantum Arrays Coupled to Metasurface Bound States in the Continuum
Daniel Eyles, Emmanuel Lassalle, Adam Stokes +2
Dicke superradiance is a collective phenomenon where the emission from ensembles of quantum emitters is coherently enhanced beyond the sum of each emitter's independent emission. H…
Sampling methods to describe superradiance in large ensembles of quantum emitters
Daniel Eyles, Emmanuel Lassalle, Adam Stokes +2
Superradiance is a quantum phenomenon in which coherence between emitters results in enhanced and directional radiative emission. Many quantum optical phenomena can be characterize…
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…
A Finite-Time Quantum Otto Engine subject to Control Noise and Enhancement Techniques
Theodore McKeever, Owen Diba, Ahsan Nazir
With the development of any quantum technology comes a need for precise control of quantum systems. Here, we evaluate the impact of control noise on a quantum Otto cycle. Whilst it…
