, 2012 The pair condensation energy of a finite-size superconducting particle is studied as a function of two control parameters. The first control parameter is the shape of the particle, and the second parameter is a position-dependent impurity introduced in ...

Neck pain and disability: A cross-sectional survey of the demographic and clinical characteristics of neck pain seen in a rheumatology clinic [PDF]
, 2004 This hospital-based cross-sectional cohort study examines the clinical and demographic features of neck pain, disability (using the Northwick Park neck pain questionnaire) and relationships to handicap in employment.

A randomised controlled trial comparing graded exercise treatment and usual physiotherapy for patients with non-specific neck pain (the GET UP neck pain trial). [PDF]
, 2012 Evidence supports exercise-based interventions for the management of neck pain, however there is little evidence of its superiority over usual physiotherapy. This study investigated the effectiveness of a group neck and upper limb exercise programme (GET)

Read-Green resonances in a topological superconductor coupled to a bath
, 2016 We study a topological superconductor capable of exchanging particles with an environment. This additional interaction breaks particle-number symmetry and can be modelled by means of an integrable Hamiltonian, building on the class of Richardson-Gaudin ...

Block product density matrix embedding theory for strongly correlated spin systems [PDF]
, 2017 Density matrix embedding theory (DMET) is a relatively new technique for the calculation of strongly correlated systems. Recently, block product DMET (BPDMET) was introduced for the study of spin systems such as the antiferromagnetic $J_1 - J_2$ model on

A new variational, information theory based atoms in molecules method [PDF]
, 2010 A new iterative Hirshfeld type AIM method, called Hirshfeld-I-Lambda, is presented. The weight function that defines the AIM is constructed by minimizing the information loss on formation of the molecule, with explicitly requiring that the promolecular ...

The Thouless theorem for matrix product states and subsequent post-density matrix renormalization group methods [PDF]
, 2013 The similarities between Hartree-Fock (HF) theory and the density-matrix renormalization group (DMRG) are explored. Both methods can be formulated as the variational optimization of a wave-function ansatz.

Projector quantum Monte Carlo with matrix product states [PDF]
, 2014 We marry tensor network states (TNS) and projector quantum Monte Carlo (PMC) to overcome the high computational scaling of TNS and the sign problem of PMC. Using TNS as trial wavefunctions provides a route to systematically improve the sign structure and

Predicting neck pain in Royal Australian Air Force fighter pilots
, 2012 Objective: Fighter pilots frequently report neck pain and injury, and although risk factors have been suggested, the relationships between risk factors and neck pain have not been quantified.

The Dicke model as the contraction limit of a pseudo-deformed Richardson-Gaudin model [PDF]
, 2014 The Dicke model is derived in the contraction limit of a pseudo-deformation of the quasispin algebra in the su(2)-based Richardson-Gaudin models. Likewise, the integrability of the Dicke model is established by constructing the full set of conserved ...
