A diagrammatic method to compute the effective Hamiltonian of driven nonlinear oscillators
Xu Xiao, Jayameenakshi Venkatraman, Rodrigo G. Cortiñas +2
In this work, we present a new diagrammatic method for computing the effective Hamiltonian of driven nonlinear oscillators. At the heart of our method is a self-consistent perturba…
A driven quantum superconducting circuit with multiple tunable degeneracies
Jayameenakshi Venkatraman, Rodrigo G. Cortinas, Nicholas E. Frattini +2
We present the experimental discovery of multiple simultaneous degeneracies in the spectrum of a Kerr oscillator subjected to a squeezing drive. This squeezing, in combination with…
On the static effective Lindbladian of the squeezed Kerr oscillator
Jayameenakshi Venkatraman, Xu Xiao, Rodrigo G. Cortiñas +1
We derive the static effective Lindbladian beyond the rotating wave approximation (RWA) for a driven nonlinear oscillator coupled to a bath of harmonic oscillators. The associated…
The squeezed Kerr oscillator: spectral kissing and phase-flip robustness
Nicholas E. Frattini, Rodrigo G. Cortiñas, Jayameenakshi Venkatraman +9
By applying a microwave drive to a specially designed Josephson circuit, we have realized an elementary quantum optics model, the squeezed Kerr oscillator. This model displays, as…
On the static effective Hamiltonian of a rapidly driven nonlinear system
Jayameenakshi Venkatraman, Xu Xiao, Rodrigo G. Cortiñas +2
We present a recursive formula for the computation of the static effective Hamiltonian of a system under a fast-oscillating drive. Our analytical result is well-suited to symbolic…
