Photon Statistics of a Single Atom Intracavity EIT-Kerr System
S. Rebić, A. S. Parkins, S. M. Tan
We explore the photon statistics of light emitted from a system comprising a single four--level atom strongly coupled to a high-finesse optical cavity mode which is driven by a coh…
Polariton Analysis of a Four-Level Atom Strongly Coupled to a Cavity Mode
S. Rebić, A. S. Parkins, S. M. Tan
We present a complete analytical solution for a single four-level atom strongly coupled to a cavity field mode and driven by external coherent laser fields. The four-level atomic s…
Diffusion Resonances in Action Space for an Atom Optics Kicked Rotor with Decoherence
A. J. Daley, A. S. Parkins, R. Leonhardt +1
We numerically investigate momentum diffusion rates for the pulse kicked rotor across the quantum to classical transition as the dynamics are made more macroscopic by increasing th…
State determination in continuous measurement
A. C. Doherty, S. M. Tan, A. S. Parkins +1
The possibility of determining the state of a quantum system after a continuous measurement of position is discussed in the framework of quantum trajectory theory. Initial lack of…
Dynamical quantum noise in Bose-Einstein condensates
M. J. Steel, M. K. Olsen, L. I. Plimak +5
We introduce the study of dynamical quantum noise in Bose-Einstein condensates through numerical simulation of stochastic partial differential equations obtained using phase space…
Phase preparation by atom counting of Bose-Einstein condensates in mixed states
R. Graham, T. Wong, M. J. Collett +2
We study the build up of quantum coherence between two Bose-Einstein condensates which are initially in mixed states. We consider in detail the two cases where each condensate is i…
