Discrete time crystals and classical logic gates in coupled open Dicke models
Emmanuel D. G. U, Roy D. Jara, Jayson G. Cosme
We investigate the dynamics of coupled discrete time crystals (DTCs) in the coupled Dicke model or Dicke dimer (DD) with dissipation. By numerically simulating the mean-field dynam…
Universal logic gates for coupled period-doubling systems
Emmanuel D. G. U, Roy D. Jara, Jayson G. Cosme
We propose a general architecture for universal logic operations using NAND and NOR gates on classical information encoded in period-doubled states of periodically-driven systems.…
Universality of dissipative discrete time crystal formation
Roy D. Jara, Jayson G. Cosme
We demonstrate that the Kibble-Zurek mechanism (KZM) holds for open systems transitioning from a disordered phase to a discrete time crystal (DTC). Specifically, we observe the cha…
Controlled bit-flip of period-doubling and discrete time crystalline states in open systems
Roy D. Jara, Phatthamon Kongkhambut, Hans Keßler +2
In this work, we explore the robustness of a bit-flip operation against thermal and quantum noise for bits represented by the symmetry-broken pairs of the period-doubled (PD) state…
Observation of a zero-energy excitation mode in the open Dicke model
Anton Bolian, Phatthamon Kongkhambut, Christoph Georges +6
Approaching phase boundaries in many-body systems can give rise to intriguing signatures in their excitation spectra. Here, we explore the excitation spectrum of a Bose-Einstein co…
Apparent delay of the Kibble-Zurek mechanism in quenched open systems
Roy D. Jara, Jayson G. Cosme
We report a new intermediate regime in the quench time, , separating the usual validity of the Kibble-Zurek mechanism (KZM) and its breakdown for rapid quenches in open syst…
Theory of parametric resonance for discrete time crystals in fully-connected spin-cavity systems
Roy D. Jara, Dennis F. Salinel, Jayson G. Cosme
We pinpoint the conditions necessary for discrete time crystal (DTC) formation in fully connected spin-cavity systems from the perspective of parametric resonance by mapping these…
