Dressing the Lorentz atom
Stephen M. Barnett, James D. Cresser, Sarah Croke
We investigate the effects of the electromagnetic vacuum field on a harmonically bound electron. We show that in the electric-dipole approximation the model atom couples only to an…
Revisiting the damped quantum harmonic oscillator
Stephen M. Barnett, James D. Cresser, Sarah Croke
We reanalyse the quantum damped harmonic oscillator, introducing three less than common features. These are (i) the use of a continuum model of the reservoir rather than an ensembl…
Time-reversed quantum trajectory analysis of micromaser correlation properties and fluctuation relations
J D Cresser
The micromaser is examined with the aim of understanding certain of its properties based on a time-reversed quantum trajectory analysis. The background theory of master equations d…
Coarse-graining in the derivation of Markovian master equations and its significance in quantum thermodynamics
J D Cresser, C Facer
The coarse-graining approach to deriving the quantum Markovian master equation is revisited, with close attention given to the underlying approximations. It is further argued that…
Theory of the strongly-damped quantum harmonic oscillator
Stephen M. Barnett, James D. Cresser, Sarah Croke
We analyse the properties of a strongly-damped quantum harmonic oscillator by means of an exact diagonalisation of the full Hamiltonian, including both the oscillator and the reser…
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…
