Torus Bifurcation of a Dissipative Time Crystal

Author(s): Jayson G. Cosme, Phatthamon Kongkhambut, Anton Bölian, Richelle Jade L. Tuquero, Jim Skulte, Ludwig Mathey, Andreas Hemmerich, and Hans Keßler 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 instability of a dissipative continuous time crystal toward a time crystalline state exhibiting two prominent oscillation freq… [Phys.
