hep-lat9912004 | we re - analyze data from available finite - temperature qcd simulations near the chiral transition , with the help of chiral random matrix theory ( chrmt ) . statistical properties of the lowest - lying eigenvalues of the staggered dirac operator for su(3 ) lattice gauge theory with dynamical fermions are examined . w... | 123 |
1304.1643 | recently we provided a microscopic derivation of the exact supergravity profile for the twisted scalar field emitted by systems of fractional d3-branes at a @xmath0 orbifold singularity . in this contribution we focus on a set - up supporting an @xmath1 sym theory with su@xmath2 gauge group and @xmath3 . we take into a... | 243 |
cond-mat9702201 | in low magnetic field , the stacked , triangular antiferromagnet cscucl@xmath0 has a helical structure incommensurate ( ic ) in the chain direction . the ic wavenumber ( from neutron diffraction experiments ) decreases with increasing field transverse to the chains , as predicted by classical theory , but then it has a... | 118 |
astro-ph0110287 | observations and theory suggest that line driven winds from hot stars and luminous accretion disks adopt a unique , critical solution which corresponds to maximum mass loss rate . we analyze the numerical stability of the infinite family of shallow wind solutions , which resemble solar wind breezes , and their transiti... | 143 |
1407.7664 | we study two species of particles in two dimensions interacting by isotropic short - range potentials with the interspecies potential fine - tuned to a @xmath0-wave resonance . their universal low - energy physics can be extracted by analyzing a properly constructed low - energy effective field theory with the renormal... | 183 |
0811.2598 | thomson s theorem states that static charge distributions in conductors only exist at the conducting surfaces in an equipotential configuration , yielding a minimal electrostatic energy . in this work we present a proof for this theorem based on the variational principle . furthermore , an analogue statement for magnet... | 128 |
