Dynamical Casimir effect in superconducting circuits: A numerical approach

We present a numerical analysis of the particle creation for a quantum field in the presence of time-dependent boundary conditions. Having in mind recent experiments involving superconducting circuits, we consider their description in terms of a scalar field in a one-dimensional cavity satisfying ge...

description We present a numerical analysis of the particle creation for a quantum field in the presence of time-dependent boundary conditions.
