Oscillator tunneling dynamics in the Rabi model
E. K. Irish, J. Gea-Banacloche
The familiar Rabi model, comprising a two-level system coupled to a quantum harmonic oscillator, continues to produce rich and surprising physics when the coupling strength becomes…
Quantum discord from system-environment correlations
Richard Tatham, Natalia Korolkova
In an initially uncorrelated mixed separable bi-partite system, quantum correlations can emerge under the action of a local measurement or local noise [A. Streltsov, H. Kampermann,…
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…
Ontological aspects of the Casimir Effect
William M. R. Simpson
The role of the vacuum, in the Casimir Effect, is a matter of some dispute: the Casimir force has been variously described as a phenomenon resulting "from the alteration, by the bo…
