چکیده
We report a monolithic THz planar Fabry–Perot cavity fabricated with wafer bonding and provided metallic mirrors subwavelength apertures. demonstrate its coupling to the cyclotron resonance of high-mobility, two-dimensional electron gas. Q factors up 89 are observed for first mode at ≃300 GHz, cooperativity C = 56.4 normalized ratio Ωω in 17.5% third 6.4%.

Photon blockade in the ultrastrong coupling regime.
We explore photon coincidence counting statistics in the ultrastrong coupling regime, where the atom-cavity coupling rate becomes comparable to the cavity resonance frequency. In this regime, usual normal order correlation functions fail to describe the output photon statistics. By expressing the electric-field operator in the cavity-emitter dressed basis, we are able to propose correlation fun...
متن کاملThermal emission in the ultrastrong coupling regime
We study thermal emission of a cavity quantum electrodynamic system in the ultrastrong-coupling regime where the atom-cavity coupling rate becomes comparable the cavity resonance frequency. In this regime, the standard descriptions of photodetection and dissipation fail. Following an approach that was recently put forward by Ridolfo et al.[arXiv:1206.0944], we are able to calculate the emission...
متن کاملSwitchable ultrastrong coupling in circuit QED.
We propose different designs of switchable coupling between a superconducting flux qubit and a microwave transmission line. They are based on two or more loops of Josephson junctions which are directly connected to a closed (cavity) or open transmission line. In both cases the circuit induces a coupling that can be modulated in strength, reaching the so-called ultrastrong coupling regime in whi...

متن کاملNonequilibrium and nonperturbative dynamics of ultrastrong coupling in open lines.
The time and space resolved dynamics of a qubit with an Ohmic coupling to propagating 1D photons is studied, from weak coupling to the ultrastrong coupling regime. A nonperturbative study based on matrix product states shows the following results, (i) The ground state of the combined systems contains excitations of both the qubit and the surrounding bosonic field. (ii) An initially excited qubi...
