Hybrid quantum magnetism in circuit-QED: from spin-photon waves to many-body spectroscopy
Andreas Kurcz, Alejandro Bermudez, Juan José García-Ripoll
We introduce a model of quantum magnetism induced by the non-perturbative exchange of microwave photons between distant superconducting qubits. By interconnecting qubits and caviti…
Bose-Hubbard models with photon pairing in circuit-QED
Benjamin Villalonga Correa, Andreas Kurcz, Juan jose Garcia-Ripoll
In this work we study a family of bosonic lattice models that combine an on-site repulsion term with a nearest-neighbor pairing term, $\sum_{< i,j>} a^\dagger_i a^\dagger_j + \math…
Environment-induced heating in sonoluminescence experiments
Almut Beige, Antonio Capolupo, Andreas Kurcz
This paper discusses a quantum optical heating mechanism which might play an important role in sonoluminescence experiments. We suggest that this mechanism occurs during the final…
A rate equation approach to cavity mediated laser cooling
Tony Blake, Andreas Kurcz, Almut Beige
The cooling rate for cavity mediated laser cooling scales as the Lamb-Dicke parameter eta squared. A proper analysis of the cooling process hence needs to take terms up to eta^2 in…
Extending the validity range of quantum optical master equations
Adam Stokes, Andreas Kurcz, Tim P. Spiller +1
This paper derives master equations for an atomic two-level system for a large set of unitarily equivalent Hamiltonians without employing the rotating wave and certain Markovian ap…
Composite quantum systems and environment-induced heating
Almut Beige, Andreas Kurcz, Adam Stokes
In recent years, much attention has been paid to the development of techniques which transfer trapped particles to very low temperatures. Here we focus our attention on a heating m…
