Strong field effects in laser pulses: the Wigner formalism
Strong field effects laser pulses
2010/12/24
We investigate strong field vacuum effects using a phase space approach based on the Wigner formalism. We calculate the Wigner function in a strong null-field background exactly, using lightfront fiel...
A nonperturbative model for the strong running coupling within potential approach
nonperturbative model potential approach
2010/12/24
A nonperturbative model for the QCD invariant charge, which contains no low-energy unphysical singularities and possesses an elevated higher loop corrections stability, is developed in the framework ...
Possible splitting of deconfinement and chiral transitions in strong magnetic fields in QCD
chiral transitions strong magnetic fields in QCD
2010/12/27
We show that finite-temperature deconfinement and chiral transitions can split in a strong enough magnetic field. The splitting in critical temperatures of these transitions in a constant magnetic fie...

We show that finite-temperature deconfinement and chiral transitions can split in a strong enough magnetic field. The splitting in critical temperatures of these transitions in a constant magnetic fie...
The extraordinary complex magnetic field of the helium-strong star HD 37776
The extraordinary complex magnetic field the helium-strong star HD 37776
2011/1/11
The early-type chemically peculiar stars often show strong magnetic fields on their surfaces. These magnetic topologies are organized on large scales and are believed to be close to an oblique dipole ...
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...
Two flavor QCD involves three independent mass parameters for which non-perturbative effects are not universal. This precludes matching lattice and perturbative results for non-degenerate quarks and e...
Exploration of the phase structure of $SU(N_c)$ lattice gauge theory with many Wilson fermions at strong coupling
the phase structure Wilson fermions
2011/1/6
We explore aspects of the phase structure of SU(2) and SU(3) lattice gauge theories at strong coupling with many flavours $N_f$ of Wilson fermions in the fundamental representation, including the rele...
Strong [O III] and [N II] emission lines in globular clusters from photoionized R Corona Borealis star winds

2011/1/13
The globular cluster X-ray source CXO J033831.8-352604 in NGC 1399 has recently been found to show strong emission lines of [O III] and [N II] in its optical spectrum in addition to ultraluminous X-ra...
Two and three-point correlators of operators dual to folded string solutions at strong coupling

2010/12/24
A particular analytic continuation of classical string solutions having a single AdS_5 spin is considered. These solutions describe strings tunnelling from the boundary to the boundary of AdS_5. We us...

The nonlinear response of electrons (holes) in doped graphene on ac pumping is concidered the-
oretically for the frequency region above the energy relaxation rate but below the momentum and

On the propagation of oceanic waves driven by a strong macroscopic flow
oceanic waves macroscopic flow
2010/11/23
In this work we study oceanic waves in a shallow water flow subject to strong wind forcing and rotation, and linearized around a inhomogeneous (non zonal) stationary profile. This extends the study \c...
Transition probabilities and dynamic structure factor in the ASEP conditioned on strong flux
Transition probabilities dynamic structure factor strong flux
2010/11/23
We consider the asymmetric simple exclusion processes (ASEP) on a ring constrained to produce an atypically large flux, or an extreme activity. Using quantum free fermion techniques we find the time-d...
Homogenization of the Vlasov Equation and of the Vlasov - Poisson System with a Strong External Magnetic Field
the Vlasov Equation the Vlasov - Poisson System
2010/11/23
Motivated by the difficulty arising in the numerical simulation of the movement of charged particles in presence of a large external magnetic field, which adds an additional time scale and thus impos...
