Investigation of nonlinear effects in Josephson parametric oscillators used in circuit QED
Philip Krantz, Yarema Reshitnyk, Waltraut Wustmann +6
We experimentally study the behavior of a parametrically pumped nonlinear oscillator, which is based on a superconducting λ/4 resonator, and is terminated by a flux-tunable SQUID.…
Generalized Bose-Einstein condensation into multiple states in driven-dissipative systems
Daniel Vorberg, Waltraut Wustmann, Roland Ketzmerick +1
Bose-Einstein condensation, the macroscopic occupation of a single quantum state, appears in equilibrium quantum statistical mechanics and persists also in the hydrodynamic regime…
Parametric resonance in tunable superconducting cavities
Waltraut Wustmann, Vitaly Shumeiko
We develop a theory of parametric resonance in tunable superconducting cavities. The nonlinearity introduced by the SQUID attached to the cavity, and damping due to connection of t…
