Fluctuation spectra of Few-and Large-degree-of-freedom Chaotic Systems
Abstract Following Fujisaka's basic idea, large deviation statistics characterizing temporal fluctuations are calculated based on Mori's projection-operator method. It is shown that this calculation will overcome the finite-sample effect studied by...

Network Analysis Based on Statistical-Thermodynamical Formalism
Abstract Random walk on a graph is analyzed on the basis of the statistical-thermodynamics formalism to find phase transitions in network structure. Each phase can be related to a characteristic local structure of the network. For this purpose, the...

Analytical study of holographic superconductor in Born–Infeld electrodynamics with backreaction
Abstract We extend the analytical studies on the properties of s-wave holographic superconductors in the presence of Born–Infeld nonlinear electrodynamics by taking the backreaction into account. We find that even in the case of nonlinear...

Dark matter search experiment with CaF2(Eu) scintillator at Kamioka Observatory
Abstract We report recent results of a WIMP dark matter search experiment using 310 g of CaF2(Eu) scintillator at Kamioka Observatory. We chose a highly radio-pure crystal, PMTs and radiation shields, so that the background rate decreased...

Casimir densities for a boundary in Robertson–Walker spacetime
Abstract For scalar and electromagnetic fields we evaluate the vacuum expectation value of the energy–momentum tensor induced by a curved boundary in the Robertson–Walker spacetime with negative spatial curvature. In order to generate the vacuum...

Flavoring the quark–gluon plasma with charm
Abstract We demonstrate that a Quark–Gluon Plasma (QGP) with a dilute admixture of heavy quarks has, in general, a lower speed of sound than a “pure” QGP without effects from heavy flavors. The change in the speed of sound is sensitive to the...

Generalized phantom energy
Abstract We examine cosmological models with generalized phantom energy (GPE). Generalized phantom energy satisfies the supernegative equation of state, but its evolution with the scale factor is generally independent, i.e., not determined by its...

Constraints on the parity-violating couplings of a new gauge boson
Abstract High-energy particle physics experiments allow for the possible existence of a new light, very weakly coupled, neutral gauge boson (the U boson). This one permits for light (spin- 1 ...

A note on the viability of Gauss–Bonnet cosmology
Abstract In this Letter, we analyze the viability of a vacuum Gauss–Bonnet cosmology by examining the dynamics of the homogeneous and anisotropic background in 4 + 1 ...

Testing CP violation in ZZH interactions at the LHC
Abstract We study genuine CP-odd observables at the LHC to test the CP property of the ZZH interaction for a Higgs boson with mass below the threshold to a pair of gauge bosons via the process p p ...

Notes on D-branes of type IIB string on AdS5×S5
Abstract We promote a study of D-branes of type IIB string on the AdS5×S5 background. The possible D-branes preserving half of supersymmetries were classified up to and including the fourth order of fermionic variable θ in our previous work...

Intermediate inflation on the brane
Abstract Brane inflationary universe model in the context of intermediate inflation is studied. General conditions for this model to be realizable are discussed. In the high-energy limit we describe in great details the characteristic of this model. ...

Double-cut of scattering amplitudes and Stokes' Theorem
Abstract We show how Stokes' Theorem, in the fashion of the Generalised Cauchy Formula, can be applied for computing double-cut integrals of one-loop amplitudes analytically. It implies the evaluation of phase-space integrals of rational functions...

Generalized second law of thermodynamics in Gauss–Bonnet braneworld
Abstract We investigate the validity the generalized second law of thermodynamics in a general braneworld model with curvature correction terms on the brane and in the bulk, respectively. Employing the derived entropy expression associated with the...

Modified dispersion relations in extra dimensions
Abstract It has recently been shown that the thermodynamics of a FRW universe can be fully derived using the generalized uncertainty principle (GUP) in extra dimensions as a primary input. There is a phenomenologically close relation between the GUP ...
