Equivariant reduction of Yang–Mills theory over the fuzzy sphere and the emergent vortices
Abstract We consider a U ( 2 ) Yang–Mills theory on M × ...

Conjugate variables in quantum field theory and natural symplectic structures
Abstract Within standard quantum field theory we establish relations which operators conjugate to the energy–momentum operator of the theory would have. They thus can be understood as representing the effect of coordinate operators. The non-trivial...

A possible resolution of the proton spin problem
Abstract A number of lines of investigation into the structure of the nucleon have converged to the point where it seems possible to propose a consistent explanation of the well known proton spin problem.

Cancelling quadratic divergences without supersymmetry
Abstract We construct a theory which has the same particle content as softly broken minimal supersymmetric QED (MSQED) and is free of quadratic divergences up to two loops. Also this theory is completely gauge invariant. It appears that MSQED is not ...

The dielectric constant of UO2 below the Ne´el point
Abstract We report measurements of the frequency-dependent dielectric constant of UO2 from 4.2 K to above the phase transition at 30 K. The static dielectric constant of 23.6 at 4.2 K is comparable with accepted values at higher temperatures: it is...

Partial molar entropy of electrons in a jellium model: Implications for thermodynamics of ions in solution and electrons in metals
Abstract A universal relationship between the partial molar entropy of electrons in a conductor and the absolute thermoelectric power of the conductor was previously established using macroscopic thermodynamics. This relationship may depend on...

Cosmology with torsion: An alternative to cosmic inflation
Abstract We propose a simple scenario which explains why our Universe appears spatially flat, homogeneous and isotropic. We use the Einstein–Cartan–Kibble–Sciama (ECKS) theory of gravity which naturally extends general relativity to include the spin ...

Modified holographic dark energy in DGP brane world
Abstract In this Letter, the cosmological dynamics of a modified holographic dark energy which is derived from the UV/IR duality by considering the black hole mass in higher dimensions as UV cutoff, is investigated in Dvali–Gabadadze–Porrati (DGP)...

Universal non-oblique corrections in Higgsless models and beyond
Abstract Recently Barbieri et al. have introduced a formalism to express the deviations of electroweak interactions from their Standard Model forms in “universal” theories, i.e., theories in which the corrections due to new physics can be expressed...

A new method for the determination of the real part of the hadron elastic scattering amplitude at small angles and high energies
Abstract A new method for the determination of the real part of the elastic scattering amplitude is examined for high energy proton–proton at small momentum transfer. This method allows us to decrease the number of model assumptions, to obtain the...

Vanishing perturbative vacuum energy in non-supersymmetric orientifolds
Abstract We present a novel source for supersymmetry breaking in orientifold models, and show that it gives a vanishing contribution to the vacuum energy at genus zero and three-half. We also argue that all the corresponding perturbative...

Proof of a universal lower bound on the shear viscosity to entropy density ratio
Abstract It has been conjectured, on the basis of the gauge-gravity duality, that the ratio of the shear viscosity to the entropy density should be universally bounded from below by 1 / ...

The pressure of QED from the two-loop 2PI effective action
Abstract We compute the pressure of hot quantum electrodynamics from the two-loop truncation of the 2PI effective action. Since the 2PI resummation guarantees gauge-fixing independence only up to the order of the truncation, our result for the...
