We study the problem of four-form flux quantization in F-theory compactifications. We prove that for smooth, elliptically fibered Calabi-Yau fourfolds with a Weierstrass representation, the flux is a...
Axial and electromagnetic observables of hyperons in 2-flavor chiral perturbation theory
Axial electromagnetic observables hyperons 2-flavor chiral perturbation theory

Two-flavor chiral expansions provide a useful perturbative framework to study hadron properties. Such expansions should exhibit marked improvement over the conventional three-flavor chiral expansion. ...

A dark energy model alternative to generalized Chaplygin gas
energy model generalized Chaplygin gas
2010/12/27
We propose a new fluid model of dark energy for $-1 \leq \omega_{\text{eff}} \leq 0$ as an alternative to the generalized Chaplygin gas models. The energy density of dark energy fluid is severely supp...
The determination of the two-body density functional from its one-body density is achieved for Moshinsky's harmonium model, using a phase-space formulation, thereby resolving its phase dilemma. The c...
Quantum dispersion relations for excitations of long folded spinning superstring in AdS_5 x S^5
Quantum dispersion relations folded spinning superstring
2010/12/23
We use AdS_5 x S^5 superstring sigma model perturbation theory to compute the leading one-loop corrections to the dispersion relations of the excitations near a long spinning string in AdS. This inves...
Scaling and non-Abelian signature in fractional quantum Hall quasiparticle tunneling amplitude
non-Abelian signature quantum Hall quasiparticle tunneling amplitude
2010/12/27
We study the scaling behavior in the tunneling amplitude when quasiparticles tunnel along a straight path between the two edges of a fractional quantum Hall annulus. Such scaling behavior originates f...
We study the nonperturbative gluon and ghost propagators in d=3 Yang-Mills, using the Schwinger-Dyson equations of the pinch technique. The use of the Schwinger mechanism leads to the dynamical genera...
Intermediate distance correlators in hot Yang-Mills theory
Intermediate distance correlators hot Yang-Mills theory
2011/1/7
Lattice measurements of spatial correlation functions of the operators FF and FF-dual in thermal SU(3) gauge theory have revealed a clear difference between the two channels at "intermediate" distance...
FV-type action for AdS(5) mixed-symmetry fields
FV-type action AdS(5) mixed-symmetry fields
2010/12/24
We formulate Fradkin-Vasiliev type theory of massless higher spin fields in AdS(5). The corresponding action functional describes cubic order approximation to gravitational interactions of bosonic mi...
We present a one-parameter extension of the raise and peel one-dimensional growth model. The model is defined in the configuration space of Dyck (RSOS) paths. Tiles from a rarefied gas hit the interfa...
Optical Lattice Hamiltonians for Relativistic Quantum Electrodynamics
Optical Lattice Hamiltonians Relativistic Quantum Electrodynamics
2011/1/7
We show how interpenetrating optical lattices containing Bose-Fermi mixtures can be constructed to emulate the thermodynamics of quantum electrodynamics (QED). We present models of neutral atoms on la...
Mapping theorem and Green functions in Yang-Mills theory
Mapping theorem Green functions Yang-Mills theory
2011/1/7
It is shown how, starting from a mapping theorem recently proved between massless quartic scalar field theory and Yang-Mills theory, both two-point functions and spectrum of the Yang-Mills theory can ...
We consider a geometric approach to field theory in which torsion is present beside gravity and also electrodynamics for the matter field equations, and we develop the consequences of the torsion-spi...
Heavy-Quark Mass and Heavy-Meson Decay Constants from QCD Sum Rules
Heavy-Quark Mass Heavy-Meson Decay Constants
2011/1/7
We present a sum-rule extraction of heavy-meson decay constants from the two-point correlator of heavy-light pseudoscalar currents. Our main concern is to control the uncertainties of the decay consta...
