Dynamical Casimir Effect in a Superconducting Coplanar Waveguide
Dynamical Casimir Effect in a Superconducting Coplanar Waveguide
We investigate the dynamical Casimir effect in a coplanar waveguide (CPW) terminated by a superconducting quantum interference device (SQUID). Changing the magnetic flux through the SQUID parametrically modulates the boundary condition of the CPW, and thereby, its effective length. Effective boundary velocities comparable to the speed of light in the …
