Galileons and naked singularities
Abstract A simple trace-coupled Galileon model is shown to admit spherically symmetric static solutions with naked spacetime curvature singularities.

Dynamics of Large Ensembles of Coupled Active and Inactive Oscillators
Abstract Here briefly reviewed are our studies of the dynamics of large ensembles composed of oscillators with qualitatively different behaviors (active: oscillatory and inactive: non-self-oscillatory). Such studies not only give insight into the...

Systematic analysis of the incoming quark energy loss in cold nuclear matter
Abstract The investigation into the fast parton energy loss in cold nuclear matter is crucial for a good understanding of the parton propagation in hot-dense medium. By means of four typical sets of nuclear parton distributions and three...

G-Curvaton
Abstract In this Letter, we study a curvaton model where the curvaton is acted by Galileon field. We calculate the power spectrum of fluctuation of G-Curvaton during inflation and discuss how it converts to the curvature perturbation after the end...

Observational constraints on unified dark matter including Hubble parameter data
Abstract We constrain a unified dark matter (UDM) model from the latest observational data. This model assumes that the dark sector is degenerate. Dark energy and dark matter are the same component. It can be described by an affine equation of state ...

Progress of PKUNIFTY – a RFQ Accelerator based Neutron Imaging Facility at Peking University
Abstract Peking University neutron imaging facility (PKUNIFTY) is a RFQ accelerator based facility, whose design principle is to scale down the size and cost as much as possible while maintaining a basic set of neutron radiography capabilities. The...

Jet and Photon Physics with ALICE: First Results from the pp Runs
Abstract During the first year of data taking ALICE has collected large data samples from pp collisions at the LHC ( s = 900 ...

Cosmology of nonlinear oscillations
Abstract The nonlinear oscillations of a scalar field are shown to have cosmological equations of state with w=p/ρ ranging from −1<w<1. We investigate the possibility that the dark energy is due to such oscillations. ...

Higgs decays in the two Higgs doublet model: large quantum effects in the decoupling regime
Abstract We study the Higgs-boson decays h0→b b ̄ , h 0→γγ and h 0→γZ within the framework of the two Higgs ...

Effect of bare mass on the Hosotani mechanism
Abstract It is pointed out that the existence of bare mass terms for matter fields changes gauge symmetry patterns through the Hosotani mechanism. As a demonstration, we study an SU(2) gauge model with massive adjoint fermions defined on M ...

Renormalization of the Cabibbo–Kobayashi–Maskawa matrix in standard model
Abstract We have investigated the present renormalization prescriptions of Cabibbo–Kobayashi–Maskawa (CKM) matrix, and found there is still not an integrated prescription to all loop levels in the on-shell renormalization scheme. In this Letter we...

A pulsed source of polarization-entangled photon pairs
Abstract We report a Bell state preparation experiment using polarization-entangled photon pairs which are produced by spontaneous parametric down conversion of a 405 nm pulse laser beam inside two orthogonally oriented 0.1 mm beta-barium borate...

New exact solution for Rayleigh–Stokes problem of Maxwell fluid in a porous medium and rotating frame
Abstract The aim of this paper is to determine the new exact solution of a magnetohydrodynamic (MHD) and rotating flow of the Maxwell fluid induced by a suddenly moved plate in its own plane. This is accomplished by using the Fourier sine and...
