The association of all three soft gamma-ray repeaters (SGRs) with supernova remnants has established that SGRs are young neutron stars, and has given us a starting point for detailed modeling. One of the most popular classes of models involves strongly magnetised neutron stars, with surface dipole fields B ∼ 10 − 10 G. In such strong magnetic fields, many otherwise negligible processes can play...

Polarisation measurements of pulsars and of their pulsar wind nebulae (PWNe) are uniquely able to provide deep insights into the highly magnetised relativistic environment of young, rotationpowered isolated neutron stars (INSs). Besides the radio band, optical observations are primarily suited to providing such insights. The first INS for which optical polarisation observations were performed i...

Neutron Spin Echo spectroscopy provides unique insight into molecular and submolecular dynamics as well as intraand inter-molecular interactions in soft matter. These dynamics may change drastically under shear flow. In particular in polymer physics a stress plateau is observed, which might be explained by an entanglement-disentanglement transition. However, such a transition is difficult to id...

One of the key features of LONGPOL, the neutron polarisation analysis instrument running in ANSTO, Australia, is the development of a real-time data acquisition and control system. The system provides separation of neutron spin-flip and nonspin-flip events and provides energy analysis through the timeof-flight method. This system is composed of five DSP boards, one is the master board, and the ...

Two distinct polarised neutron techniques are applicable to the. study of magnetic diffuse scattering. The first, used for ferromagnetic alloys, employs a polarised incident beam without analysis of the outgoing polarisation. This method has been widely used, chiefly by the Oak Ridge group, to study moment disturbances in ferromagnetic binary transition metal alloys. The second technique involv...

Fast Radio Bursts (FRBs) are intense, millisecond-duration broadband radio transients, the emission mechanisms of which are not understood. Masui et al. recently presented Green Bank Telescope observations of FRB 110523, which displayed temporal variation of the linear polarisation position angle (PA). This effect is commonly seen in radio pulsars and is attributed to a changing projected magne...

The Meissner effect in a thin-film superconductor can be used to create a sharp boundary between regions of different magnetic field and hence can be used as a component of neutron spin manipulation devices. We have developed two cryogenic neutron spin manipulation devices using single-crystal, high-Tc, YBCO films, which can be cooled without using liquid cryogens and eliminate small angle scat...

Polarised neutron scattering is the method of choice to study magnetism in condensed matter. neutrons are typically very low flux, and complex experimental configurations further reduce count rate. Neutron polarisation corrections would therefore be needed. Here we analytically derive formulae corrected partial differential cross-sections. The analytical designed for longitudinal analysis, corr...
