Spiral inflation
Abstract We propose a novel scenario of primordial inflation in which the inflaton goes through a spiral motion starting from around the top of a symmetry breaking potential. We show that, even though inflation takes place for a field value much...

Renormalised fermion vacuum expectation values on anti-de Sitter space–time
Abstract The Schwinger–de Witt and Hadamard methods are used to obtain renormalised vacuum expectation values for the fermion condensate, charge current and stress-energy tensor of a quantum fermion field of arbitrary mass on four-dimensional...

Bridges in the random-cluster model
Abstract The random-cluster model, a correlated bond percolation model, unifies a range of important models of statistical mechanics in one description, including independent bond percolation, the Potts model and uniform spanning trees. By...

High-resolution determination of GT strength distributions relevant to the presupernova evolution using the (d,2He) reaction
Abstract Spin–isospin excitations of the medium-mass nucleus 58Co were studied using the (n,p)-type (d,2 He) charge-exchange reaction at an incident energy E d ...

Generalised Unitarity for Dimensionally Regulated Amplitudes
Abstract We present a novel set of Feynman rules and generalised unitarity cut-conditions for computing one-loop amplitudes via d-dimensional integrand reduction algorithm. Our algorithm is suited for analytic as well as numerical result, because...

Long Range Order and Spin-Fluctuations in Strongly Correlated Electron System with Valence Instability
Abstract Rare-earth based strongly correlated electron systems (SCES) exhibit a large variety of different ground states, ranging from the simple paramagnetism of crystal-field-split f-electron multiplets to highly unconventional Kondo-insulator...

On the decay of a sawtooth profile in non-ideal magneto-gasdynamics
Abstract In the present paper, an asymptotic approach is used to analyse the main features of weakly nonlinear waves propagating in a compressible, inviscid, nonideal gas in the presence of magnetic field. An evolution equation, which characterizes...

Investigation of Magnetic and Magnetoelastic Properties of the Unconventional Heavy-fermion Compound CeCu2Ge2
Abstract Heavy-fermion compounds, high-T c cuprates or iron pnictides are characterized by adjacent properties and a rich magnetic phase diagram with unconventional or competing states at low temperatures. CeCu2Ge2, the...

Detectability of a subdominant density component of cold dark matter
Abstract Here we examine the detectability of collisionless dark matter candidates that may constitute not all but only a subdominant component of galactic cold dark matter. We show that direct WIMP searches would not be severely affected by the...

Neutron-induced Fission Measurements at the Time-of-Flight Facility nELBE
Abstract Neutron-induced fission of 242Pu is studied at the photoneutron source nELBE. The relative fast neutron fission cross section was determined using actinide fission chambers in a time-of-flight experiment. A good agreement of present nuclear ...

Josephson junction of non-Abelian superconductors and non-Abelian Josephson vortices
Abstract A Josephson junction is made of two superconductors sandwiching an insulator, and a Josephson vortex is a magnetic vortex (flux tube) absorbed into the Josephson junction, whose dynamics can be described by the sine-Gordon equation. In a...

Inverse magnetic catalysis in Nambu–Jona-Lasinio model beyond mean field
Abstract We study inverse magnetic catalysis in the Nambu–Jona-Lasinio model beyond mean field approximation. The feed-down from mesons to quarks is embedded in an effective coupling constant at finite temperature and magnetic field. While the...

Validation of Monte Carlo Geant4 code for a 6MV Varian linac
Abstract This study is aimed at validating the Monte Carlo Geant4.9.4 code for a 6MV Varian linac configuring a 10×10cm2 radiation field. For this purpose a user-friendly Geant4 code called G4Linac has been developed from scratch allowing an...

Gravitational gauge mediation
Abstract It is often the case that the naive introduction of the messenger sector to supersymmetry breaking models causes restoration of supersymmetry. We discuss a possibility of stabilizing the supersymmetry breaking vacuum by gravitational...
