0711.1112 | we find new non - abelian flux tube solutions in a model of @xmath0 scalar fields in the fundamental representation of @xmath1 with @xmath2 ( the `` extended non - abelian higgs model '' ) , and study their main properties . among the solutions there are spinning strings as well as superconducting ones . the solutions ... | 119 |
1112.4673 | it is known that any subharmonic quadrature domain in two dimensions satisfies a natural inner ball condition , in other words there is a specific upper bound on the curvature of the boundary . this result directly applies to free boundaries appearing in obstacle type problems and in hele - shaw flow . in the present p... | 120 |
0806.4266 | an infinite family of axially symmetric thin disks of finite radius is presented . the family of disks is obtained by means of a method developed by hunter and contains , as its first member , the kalnajs disk . the surface densities of the disks present a maximum at the center of the disk and then decrease smoothly to... | 190 |
nucl-th0106054 | the strangeness - changing ( @xmath0 ) weak baryon - baryon interaction is studied through the nonmesonic weak decay of double-@xmath1 hypernuclei . besides the usual nucleon - induced decay @xmath2 we discuss novel hyperon - induced decay modes @xmath3 and @xmath4 . these reactions provide unique access to the exotic ... | 159 |
