Bulk viscous L.R.S. Bianchi type V tilted stiff fluid cosmological model in general relativity
Abstract Locally rotationally symmetric (L.R.S.) Bianchi type V bulk viscous tilted stiff fluid cosmological model is investigated. To get the deterministic model of the universe, we have also assumed a condition A ...

Unparticle physics with jets
Abstract Using methods of effective field theory, we show that after resummation of Sudakov logarithms the spectral densities of interacting quark and gluon fields in ordinary quantum field theories such as QCD are virtually indistinguishable from...

Equations of motion for zeros of orthogonal polynomials related to the Toda lattices
Abstract We study the motion of zeros of time dependent orthogonal polynomials. We also relate the tau function of a Toda type lattice to the discriminant of the corresponding orthogonal polynomials which is then related to the free energy of an...

Exact third-order density perturbation and one-loop power spectrum in general dark energy models
Abstract Under the standard perturbation theory (SPT), we obtain the fully consistent third-order density fluctuation and kernels for the general dark energy models without using the Einstein–de Sitter (EdS) universe assumption for the first time....

Matrix algorithms for solving (in)homogeneous bound state equations
Abstract In the functional approach to quantum chromodynamics, the properties of hadronic bound states are accessible via covariant integral equations, e.g. the Bethe–Salpeter equation for mesons. In particular, one has to deal with linear,...

Indirect searches for dark matter
Abstract The indirect detection of particle dark matter (DM) is based on the search for anomalous components in cosmic rays (CRs) due to the annihilation of DM pairs in the galactic halo, on the top of the standard astrophysical production. We...

Extremal Optimization for Ground States of the Sherrington-Kirkpatrick Spin Glass with Levy Bonds
Abstract Ground states of Ising spin glasses on fully connected graphs are studied for a broadly distributed bond family. In particular, bonds J distributed according to a Levy distribution P(J) / 1/|J|1+α; |J| > 1; are investigated for a range...

Frequency of occurrence of LCS per cascade in bcc iron by PKA energy 30 keV
Abstract The frequency of occurrence per cascade in bcc iron is studied by PKA energy 30keV using the fitting of potentials on linear collision sequences (LCS). Two embedded atom potentials that essentially differ by their repulsive branches are...

SO(3) massive gravity
Abstract In this Letter, we propose a massive gravity theory with 5 degrees of freedom. The mass term is constructed by 3 Stückelberg scalar fields, which respects SO(3) symmetry in the fieldsʼ configuration. By the analysis on the linear...

Prompt Gamma Emission in Resonance Neutron Induced Fission of 239Pu
Abstract The scientific interest in the resonance neutron induced capture and fission reactions on 239Pu is continuously rising during the last decade. From a practical point of view, this is because more precise data on capture and fission cross...

The Magnetic Phase of Lithium Transition Metal Phosphates LiMPO4 (M=Mn, Co, Ni) Detected by μ+SR
Abstract The magnetic properties of the olivine-type compounds LiMPO4 (M = Mn, Co, Ni) are probed using muon spin rotation/relaxation (μSR). These materials pose an appealing magnetic structure and a high -potential technological interest as cathode ...

Study on Artificial Neural Network Method for Ground Subsidence Prediction of Metal Mine
Abstract Metal mine with fractured blocky rock mass is much different from coal mine, which shows discontinuity and irregularity, meanwhile large differences also exist in stratum structure, geological condition, ore body shape and mining methods,...
