We theoretically investigate the dynamical Casimir effect (DCE) in electrical circuits based on superconducting microfabricated waveguides with tunable boundary conditions. We propose implementing a rapid modulation of the boundary conditions by tuning the applied magnetic flux through superconducting quantum-interference devices that are embedded in the waveguide circuits. We consider two circuits: (i) An open waveguide circuit that corresponds to a single mirror in free space, and (ii) a… 
Dynamical Casimir effect in a Josephson metamaterial
The zero-point energy stored in the modes of an electromagnetic cavity has experimentally detectable effects, giving rise to an attractive interaction between the opposite walls, the static Casimir
Superconducting circuit boundary conditions beyond the Dynamical Casimir Effect
We study analytically the time-dependent boundary conditions of superconducting microwave circuit experiments in the high plasma frequency limit, in which the conditions are Robin-type and relate the
Dynamical Casimir effect in dissipative superconducting circuit system
We investigate the possibility of observing in integrated solid-state systems the dynamical Casimir effect, in which photons are created out of vacuum. We use a transmission line resonator on a
Microwave photon generation in a doubly tunable superconducting resonator
We have created a doubly tunable resonator, with the intention to simulate relativistic motion of the resonator boundaries in real space. Our device is a superconducting coplanar-waveguide microwave
Parametric interactions with signals and the vacuum
In this thesis I present different experiments on superconducting circuits exploring parametric interactions with external signals and the vacuum in the microwave regime. These parametric processes

Dynamical Casimir effect of phonon excitation in the dispersive regime of cavity optomechanics
In this paper, we theoretically propose and investigate a feasible experimental scheme to realize the dynamical Casimir effect (DCE) of phonons in an optomechanical setup formed by a ground-state
Parametric resonance in tunable superconducting cavities
We develop a theory of parametric resonance in tunable superconducting cavities. The nonlinearity introduced by the superconducting quantum interference device (SQUID) attached to the cavity and
From strong to ultrastrong coupling in circuit QED architectures
The field of cavity quantum electrodynamics (cavity QED) studies the interaction between light and matter on a fundamental level: a single atom interacts with a single photon. If the atom-photon
