Five-dimensional rotating black holes in Einstein–Gauss–Bonnet theory
Abstract We present arguments for the existence of five-dimensional rotating black holes with equal magnitude angular momenta in Einstein–Gauss–Bonnet theory with negative cosmological constant. These solutions posses a regular horizon of spherical...

Yang's model as triply special relativity and the Snyder's model–de Sitter special relativity duality
Abstract We show that if Yang's quantized space–time model is completed at both classical and quantum level, it should contain both Snyder's model, the de Sitter special relativity and their duality.

Unparticle effects on top quark rare decays
Abstract In this work we study the flavor changing neutral current (FCNC) decays of the top quark, t → c γ and ...

Isospin symmetry breaking in 93Tc and statistical properties
Abstract We present a statistical analysis of proton resonances in the compound nucleus 93Tc in terms of random matrix theory (RMT). The fluctuation properties of energy levels and reduced widths from data measured by Bilpuch et al. [Phys. Rev. C 9...

Rotating regular solutions in Einstein–Yang–Mills–Higgs theory
Abstract We construct new axially symmetric rotating solutions of Einstein–Yang–Mills–Higgs theory. These globally regular configurations possess a nonvanishing electric charge which equals the total angular momentum, and zero topological charge,...

Inflationary solution to the strong CP and μ problems
Abstract We show that the vacuum expectation value of the inflaton at the Peccei–Quinn axion scale can generate the supersymmetric Higgs mass μ term. This provides an inflationary simultaneous solution to the strong CP problem and the μ problem of...

Nonlinearly realized local scale invariance: gravity and matter
Abstract That the scalar field theories with no dimensional couplings possess local scale invariance (LSI) via the curvature gauging is utilized to show that the Goldstone boson, released by the spontaneous LSI breakdown, is swallowed by the...

Parametrization of Bose–Einstein correlations and reconstruction of the space–time evolution of pion production in e+e− annihilation
Abstract A parametrization of the Bose–Einstein correlation function of pairs of identical pions produced in hadronic e+e− annihilation is proposed within the framework of a model (the τ-model) in which space–time and momentum space are very...

Complete inclusion of parity-dependent level densities in the statistical description of astrophysical reaction rates
Abstract Microscopic calculations show a strong parity dependence of the nuclear level density at low excitation energy of a nucleus. Previously, this dependence has either been neglected or only implemented in the initial and final channels of...

Cation distribution and mixing thermodynamics in Fe/Ni thiospinels
Abstract The structural analogy between Ni-doped greigite minerals (Fe3S4) and the (Fe,Ni)S clusters present in biological enzymes has led to suggestions that these minerals could have acted as catalysts for the origin of life. However, little is...

Weak localization properties of graphene with intrinsic and Rashba spin-orbit couplings
Abstract We propose the notion of counting the number of activated spins to identify the weak localization properties of graphene under effects of inter-valley scattering, intrinsic and Rashba spin-orbit interactions (SOI). It is predicted that...

Spatial Correlations in Glass-Forming Liquids Across The Mode-Coupling Crossover
Abstract We discuss a novel approach, the point-to-set correlation functions, that allows to determine relevant static and dynamic length scales in glass-forming liquids. We find that static length scales increase monotonically when the temperature...

Dual massive gravity
Abstract The linearized massive gravity in three dimensions, over any maximally symmetric background, is known to be presented in a self-dual form as a first order equation which encodes not only the massive Klein–Gordon type field equation but also ...

Water Simulation Method Based on BPNN Response and Analytic Geometry
Abstract With three-year monthly monitoring data (from Jan. 2007 to Dec. 2009) of ten given sections of one river in Beijing, a BP neural network of DO and principle components are built by taking the concentration of DO as the evaluation criterion...

CGC/saturation approach for soft interactions at high energy: Inclusive production
Abstract In this letter we demonstrate that our dipole model is successful in describing inclusive production within the same framework as diffractive physics. We believe that this achievement stems from the fact that our approach incorporates the...

Enhanced imaging in low dose electron microscopy using electron counting
Abstract We compare the direct electron imaging performance at 120keV of a monolithic active pixel sensor (MAPS) operated in a conventional integrating mode with the performance obtained when operated in a single event counting mode. For the...

Three generations of Higgses and the cyclic groups
Abstract Multi-Higgs doublet models are interesting extensions of the Standard Model that can be related to flavor. The reason is that most flavor models usually involve the presence of several additional scalar fields. In this work we present an...

Twisted Graph States for Ancilla-driven Universal Quantum Computation
Abstract We introduce a new paradigm for quantum computing called Ancilla-Driven Quantum Computation (ADQC) which combines aspects both of the quantum circuit [D. Deutsch. Quantum computational networks. Proc. Roy. Soc. Lond A, 425, 1989] and the...
