Intensity and amplitude correlations in the fluorescence from atoms with interacting Rydberg states
Qing Xu, Klaus Mølmer
We explore the fluorescence signals from a pair of atoms driven towards Rydberg states on a three-level ladder transition. The dipole--dipole interactions between Rydberg excited a…
Correlation functions and conditioned quantum dynamics in photodetection theory
Qing Xu, Eliska Greplova, Brian Julsgaard +1
Correlations in photodetection signals from quantum light sources are conventionally calculated by application of the source master equation and the quantum regression theorem. In…
Dynamics of Entanglement in one and two-dimensional spin systems
Gehad Sadiek, Qing Xu, Sabre Kais
We present a review of dynamics of entanglement in one and two dimensional systems under the effect of external magnetic field and different degrees of anisotropy at zero and finit…
Tuning entanglement and ergodicity in two-dimensional spin systems using impurities and anisotropy
Gehad Sadiek, Qing Xu, Sabre Kais
We consider the entanglement in a two dimensional XY model in an external magnetic field h. The model consists of a set of 7 localized spin-1/2 particles in a two dimensional trian…
