Conductivity at finite 't Hooft coupling from AdS/CFT
Abstract We use the AdS/CFT correspondence to study the DC conductivity of massive N = 2 hypermultiplet fields in an N ...

The complex Laguerre symplectic ensemble of non-Hermitian matrices
Abstract We solve the complex extension of the chiral Gaussian symplectic ensemble, defined as a Gaussian two-matrix model of chiral non-Hermitian quaternion real matrices. This leads to the appearance of Laguerre polynomials in the complex plane...

“Semi-realistic” F-term inflation model building in supergravity
Abstract We describe methods for building “semi-realistic” models of F-term inflation. By semi-realistic we mean that they are built in, and obey the requirements of, “semi-realistic” particle physics models. The particle physics models are taken to ...

Elementary particles, holography and the BMS group
Abstract In the context of asymptotically flat space–times, it has been suggested to label elementary particles as unitary irreducible representations of the BMS group. We analyse this idea in the spirit of the holographic principle advocating the...

Particle energy and Hawking temperature
Abstract Some authors have recently found that the tunneling approach gives a different Hawking temperature for a Schwarzschild black hole in a different coordinate system. In this Letter, we find that to work out the Hawking temperature in a...

Note on a fermionic solution of the matrix model and noncommutative superspace
Abstract We present a new fermionic solution of the supersymmetric matrix model. The solution satisfies the commutation and anticommutation relations for noncommutative superspace. Therefore the solution can be considered as an implementation of...

CPT-violating effects in muon decay
Abstract We consider low-energy CPT-violating modifications in charged current weak interactions and analyze possible ramifications in muon and antimuon decays. We calculate the lifetime of muon and antimuon with these modifications, and from the...

Generalized eikonal knots and new integrable dynamical systems
Abstract A new class of non-linear O ( 3 ) models is introduced. It is shown that these systems lead to integrable submodels if an ...

Gravitino dark matter in gravity mediation
Abstract We study general conditions for the gravitino to be the lightest supersymmetric particle (LSP) in models with gravity mediated supersymmetry breaking. We find that the decisive quantities are the Kähler potential K and the gauge kinetic...

Effective constraint potential in lattice Weinberg–Salam model
Abstract We investigate lattice Weinberg–Salam model without fermions for the value of the Weinberg angle θ W ∼ ...

Anomalous dimension of Dirac's gauge-invariant nonlocal order parameter in Ginzburg–Landau field theory
Abstract In a Ginzburg–Landau theory with n fields, the anomalous dimension of the gauge-invariant nonlocal order parameter defined by the long-distance limit of Dirac's gauge-invariant two-point function is calculated. The result is exact for all n ...

Interacting HDE and NADE in Brans–Dicke chameleon cosmology
Abstract Motivated by the recent work of one of us Setare and Jamil (2010) [1], we generalize this work to the case where the pressureless dark matter and the holographic dark energy do not conserve separately but interact with each other. We...

The logarithmic contribution to the QCD static energy at N4LO
Abstract Using pNRQCD and known results for the field strength correlator, we calculate the ultrasoft contribution to the QCD static energy of a quark–antiquark pair at short distances at N4LO in ...

Neutrino mixing discriminates geo-reactor models
Abstract Geo-reactor models suggest the existence of natural nuclear reactors at different deep-earth locations with loosely defined output power. Reactor fission products undergo beta decay with the emission of electron antineutrinos, which...

First law of thermodynamics on holographic screens in entropic force frame
Abstract Imposing a mathematical definition of holographic screen, in the spirit of Verlindeʼs entropic force proposal (E.P. Verlinde, arXiv:1001.0785), we give the differential and integral form of the first law of thermodynamics on the holographic ...

Gluonic phase versus LOFF phase in two-flavor quark matter
Abstract We study the gluonic phase in a two-flavor color superconductor as a function of the ratio of the gap over the chemical potential mismatch, Δ / δ ...

Quasinormal modes in the background of charged Kaluza–Klein black hole with squashed horizons
Abstract We study the scalar perturbation in the background of the charged Kaluza–Klein black holes with squashed horizons. We find that the position of infinite discontinuities of the heat capacities can be reflected in quasinormal spectrum. This...

Sivers effect in semi-inclusive DIS and in the Drell–Yan process
Abstract The Sivers parton distribution function has been predicted to obey a particular “universality relation”, namely, to have opposite sign in semi-inclusive deeply inelastic scattering (SIDIS) and the Drell–Yan process. We discuss how, on the...
