Discovery reveals a reversible magnetic field around a fast radio burst for the first time
快速射电暴 可逆磁场 无线电波闪光
2023/5/15
An international team of researchers has revealed new evidence on the nature of mysterious fast radio bursts (FRBs) – objects in space that produce brief, intense flashes of radio waves from distant g...
We consider the motion of a particle in a random isotropic force field. Assuming that the force field arises from a Poisson field in R d, d ≥ 4, and the initial velocity of the parti...
Tachyonic Field Theory and Neutrino Mass Running
Tachyonic Field Theory Neutrino Mass Running High Energy Physics Phenomenology
2012/5/17
In this paper three things are done. (i) We investigate the analogues of Cerenkov radiation for the decay of a superluminal neutrino and calculate the Cerenkov angles for the emission of a photon thro...
Boost modes for a massive fermion field
boost symmetry fermion field Wightman function zero mode
2011/9/29
Abstract: We have shown that Wightman function of a free quantum field generates any complete set of solutions of relativistic wave equations. Using this approach we have constructed the complete set ...
Periodically driven dynamics of a particle moving in the field of Coulomb plus confining potential
Periodically driven dynamics particle moving the field of Coulomb
2011/9/15
Periodically driven dynamics of a particle moving in the field Coulomb plus confining potential is treated for one and three dimensional cases. Critical value of the external field strength at which c...
We derive semi-analytic formulae for the local bispectrum and trispectrum in general two-field inflation and provide a simple geometric recipe for building observationally allowed models with observa...
Quark mass dependence of the vacuum electric conductivity induced by the magnetic field in SU(2) lattice gluodynamics

We study the electric conductivity of the vacuum of quenched SU(2) lattice gauge theory induced by the magnetic field B as a function of the bare quark mass m. The conductivity grows as the quark mass...

Regge Field Theory in zero transverse dimensions: loops versus "net" diagrams
Regge Field Theory zero transverse dimensions
2010/12/23
Toy models of interacting Pomerons with triple and quaternary Pomeron vertices in zero transverse dimension are investigated. Numerical solutions for eigenvalues and eigenfunctions of the correspondin...

Field theory aspects of cosmology black holes
2010/12/24
In this thesis we study some aspects of cosmology and black holes using field theoretic techniques. In second chapter, we present Lagrangian formulation for the non-relativistic as well as relativisti...

Quantum Field Theory Black Holes Holography
2010/12/24
These notes are an expanded version of lectures given at the Croatian School on Black Holes at Trpanj, June 21-25, 2010. The aim is to provide a practical introduction to quantum field theory in curv...
Electromagnetically superconducting phase of QCD vacuum induced by strong magnetic field
Electromagnetically superconducting QCD vacuum induced
2011/1/7
In this talk we discuss our recent suggestion that the QCD vacuum in a sufficiently strong magnetic field (stronger than 10^{16} Tesla) may undergo a spontaneous transition to an electromagnetically s...
Infrared behavior and gauge artifacts in de Sitter spacetime. I. The photon field
Infrared behavior gauge artifacts
2010/12/27
We study the infrared (long distance) behavior of the free photon field in de Sitter spacetime. Using a two-parameter family of gauge fixing terms, we show that the infrared (IR) behavior of the two-...
