Controlled bit-flip of period-doubling and discrete time crystalline states in open systems
Roy D. Jara, Phatthamon Kongkhambut, Hans KeÃler +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…

Torus bifurcation of a dissipative time crystal
Jayson G. Cosme, Phatthamon Kongkhambut, Anton Bölian +5
Using a quantum gas setup consisting of a Bose-Einstein condensate strongly coupled to a high-finesse optical cavity by a transverse pump laser, we experimentally observe an instab…

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…
