Generating strong squeezing in the dispersive regime of the quantum Rabi model
Chaitanya Joshi, Elinor K. Irish, Timothy P. Spiller
We present a protocol to generate a large degree of squeezing of a boson (light) field mode strongly coupled to a two-level system in the dispersive regime. Our protocol exploits t…
Dissipation-assisted quantum correlations in coupled qubits
Chaitanya Joshi
We theoretically investigate a possibility to establish multi-qubit quantum correlations in one-dimensional chains of qubits. We combine a reservoir engineering strategy with coher…
Quantum state engineering in hybrid open quantum systems
Chaitanya Joshi, Jonas Larson, Timothy P. Spiller
We investigate a possibility to generate non-classical states in light-matter coupled noisy quantum systems, namely the anisotropic Rabi and Dicke models. In these hybrid quantum s…
Cavity assisted generation of sustainable macroscopic entanglement of ultracold gases
Chaitanya Joshi, Jonas Larson
Prospects for reaching persistent entanglement between two spatially separated atomic Bose-Einstein condensates are outlined. The system set-up comprises of two condensates loaded…
Quantum correlations in the 1-D driven dissipative transverse field XY model
Chaitanya Joshi, Felix Nissen, Jonathan Keeling
We study the non-equilibrium steady state (NESS) of a driven dissipative one-dimensional system near a critical point, and explore how the quantum correlations compare to the known…
Markovian evolution of strongly coupled harmonic oscillators
Chaitanya Joshi, Patrik Ohberg, James D. Cresser +1
We investigate how to model Markovian evolution of coupled harmonic oscillators, each of them interacting with a local environment. When the coupling between the oscillators is wea…
An all-optical feedback assisted steady state of an optomechanical array
Chaitanya Joshi, Uzma Akram, G. J. Milburn
We explore the effect of all-optical feedback on the steady state dynamics of optomechanical arrays arising from various topologies. First we consider an array comprised of a pair…
Entanglement of distant optomechanical systems
Chaitanya Joshi, Jonas Larson, Mats Jonson +2
We theoretically investigate the possibility to generate non-classical states of optical and mechanical modes of optical cavities, distant from each other. A setup comprised of two…
Constructive role of dissipation for driven coupled bosonic modes
Chaitanya Joshi, Mats Jonson, Patrik Ohberg +1
We theoretically investigate a system of two coupled bosonic modes subject to both dissipation and external driving. We show that in the steady state the degree of entanglement bet…
Quantum entanglement of anharmonic oscillators
Chaitanya Joshi, Mats Jonson, Erika Andersson +1
We investigate the quantum entanglement dynamics of undriven anharmonic (nonlinear) oscillators with quartic potentials. We first consider the indirect interaction between two such…
Quantum entanglement of nanocantilevers
C. Joshi, A. Hutter, F. E. Zimmer +3
We propose a scheme to entangle two mechanical nanocantilevers through indirect interactions mediated by a gas of ultra cold atoms. We envisage a system of nanocantilevers magnetic…
