Localisation of coastal trapped waves by longshore variations in bottom topography
Abstract Variations in shelf geometry mean that a coastal trapped wave mode can propagate within some finite length of shelf but be evanescent outside this region. This paper constructs such geographically localised coastal trapped waves using a...

Renormalisability of the matter determinants in noncommutative gauge theory in the enveloping-algebra formalism
Abstract We consider noncommutative gauge theory defined by means of Seiberg–Witten maps for an arbitrary semisimple gauge group. We compute the one-loop UV divergent matter contributions to the gauge field effective action to all orders in the...

Magneto-optical effects of transparent magnetic diffraction gratings
Abstract Magneto-optical effects of transparent magnetic diffraction gratings composed of bismuth-substituted yttrium-iron-garnet (Bi2YFe5O12) were investigated. The off-diagonal components of the dielectric tensor of the grating are imaginary and...

Cosmological solutions with massive gravitons
Abstract We present solutions describing spatially closed, open, or flat cosmologies in the massive gravity theory within the recently proposed tetrad formulation. We find that the effect of the graviton mass is equivalent to introducing to the...

On the Hamiltonian analysis of non-linear massive gravity
Abstract In this Letter we present a very simple and independent argument for the absence of the Boulware–Deser ghost in the recently proposed potentially ghost-free non-linear massive gravity. The limitation is that, in its simple form, the...

On classicalization in nonlinear sigma models
Abstract We consider the phenomenon of classicalization in nonlinear sigma models with both positive and negative target space curvature and with any number of derivatives. We find that the theories with only two derivatives exhibit a weak form of...

Implications of a 125 GeV Higgs for supersymmetric models
Abstract Preliminary results of the search for a Standard Model like Higgs boson at the LHC with 5 fb−1 data have just been presented by the ATLAS and CMS Collaborations and an excess of events at a mass of ≈ ...

Lifting the Gribov ambiguity in Yang–Mills theories
Abstract We propose a new one-parameter family of Landau gauges for Yang–Mills theories which can be formulated by means of functional integral methods and are thus well suited for analytic calculations, but which are free of Gribov ambiguities and...

Minimal violation of flavour and custodial symmetries in a vectophobic Two-Higgs-Doublet-Model
Abstract Tree-level accidental symmetries are known to play a fundamental role in the phenomenology of the Standard Model (SM) for electroweak interactions. So far, no significant deviations from the theory have been observed in precision, flavour...

Nonsmooth dynamics in spiking neuron models
Abstract Large scale studies of spiking neural networks are a key part of modern approaches to understanding the dynamics of biological neural tissue. One approach in computational neuroscience has been to consider the detailed electrophysiological...

Homotopy analysis method for the fractional nonlinear equations
Abstract In this paper, the homotopy analysis method is extended to investigate the numerical solutions of the fractional nonlinear wave equation. The numerical results validate the convergence and accuracy of the homotopy analysis method. Finally,...

Further optimisation of a simple X-ray diffraction instrument for portable and planetary applications
Abstract This paper extends the work presented in a previous publication (Hansford, 2011 [1], subsequently referred to as Paper 1) to optimise the performance of a simple reflection-mode X-ray diffraction instrument with respect to the geometrical...
