Quantized resonator field coupled to a current-biased Josephson junction in circuit QED
Christian Kraglund Andersen, Gregor Oelsner, Evgeni Il'ichev +1
A Lagrangian formalism is used to derive the Hamiltonian for a /4 resonator shunted by a current-biased Josephson junction. The eigenstates and the quantum dynamics of the syste…

Effective description of tunneling in a time-dependent potential with applications to voltage switching in Josephson junctions
Christian Kraglund Andersen, Klaus Mølmer
We propose to use a time-dependent imaginary potential to describe quantum mechanical tunneling through time-varying potential barriers. We use Gamow solutions for stationary tunne…
