Dynamics of transient cat-states in degenerate parametric oscillation with and without nonlinear Kerr interactions
R. Y. Teh, F. -X. Sun, R. E. S. Polkinghorne +4
A cat-state is formed as the steady-state solution for the signal mode of an ideal, degenerate parametric oscillator, in the limit of negligible single-photon signal loss. In the p…
Schrödinger cats and steady states in subharmonic generation with Kerr nonlinearities
Feng-Xiao Sun, Qiongyi He, Qihuang Gong +3
We discuss general properties of the equilibrium state of parametric down-conversion in superconducting quantum circuits with detunings and Kerr anharmonicities, in the strongly no…
Discrete time symmetry breaking in quantum circuits: exact solutions and tunneling
Feng-Xiao Sun, Qiongyi He, Qihuang Gong +3
We discuss general properties of discrete time quantum symmetry breaking in degenerate parametric oscillators. Recent experiments in superconducting quantum circuit with Josephson…
Emergence and stability of spontaneous vortex lattices in exciton-polariton condensates
F. X. Sun, Z. X. Niu, Q. H. Gong +2
The spontaneous formation of lattice structure of quantized vortices is a characteristic feature of superfluidity in closed systems under thermal equilibrium. In exciton-polariton…
