This paper provides a theoretical background for the simulations of particular quantum optics experiments, namely, photon intensity correlation measurements. A practical example, adapted to polarisation-entangled photon pairs emitted from a quantum dot, is presented. The tool, a virtual Hanbury Brown and Twiss correlator, simulates polarisation-resolved the second-order correlation functions, w...

The polarisation of prompt ψ(2S) mesons is measured by performing an angular analysis of ψ(2S) → μ + μ − decays using proton-proton collision data, corresponding to an integrated luminosity of 1.0 fb −1 , collected by the LHCb detector at a centre-of-mass energy of 7 TeV. The polarisation is measured in bins of transverse momentum p T and rapidity y in the kinematic region 3.5 < p T < 15 GeV/c ...

We numerically compute light and polarisation curves of γ-ray burst afterglows for various configurations of the jet luminosity structure and for different dynamical evolutions. We especially consider the standard homogeneous “top hat” jet and the “universal structured jet” with power-law wings. We also investigate a possible more physical variation of the “top hat” model: the “Gaussian jet”. T...

Polarisation states are described by spin expectation values, known as Stokes parameters, the trajectories of which in a rotationally symmetric system form sphere named after Poincaré. Here, we show that broken rotational systems can exhibit distinct topological structures polarisation states. We use phase-shifter to circle <mml:m...

The sensitivity of Magnetic Resonance Imaging (MRI) depends strongly on nuclear spin polarisation and, motivated by this observation, dynamical nuclear spin polarisation has recently been applied to enhance MRI protocols (Kurhanewicz, J., et al., Neoplasia 13, 81 (2011)). Nuclear spins associated with the C carbon isotope (nuclear spin I = 1/2) in diamond possess uniquely long spin lattice rela...

We report on a comparative study of the low temperature emission and polarisation properties of InGaN/GaN quantum wells grown on nonpolar ([Formula: see text]) a-plane and ([Formula: see text]) m-plane free-standing bulk GaN substrates where the In content varied from 0.14 to 0.28 in the m-plane series and 0.08 to 0.21 for the a-plane series. The low temperature photoluminescence spectra from b...
