A Nielsen-Olesen vortex usually sits in an environment that expels the flux that is confined to the vortex, so flux is not present both inside and outside. [...]

Math. ; Humboldt U., Berlin) ; Heslop, Paul (Durham U., Dept. of Math.) ; Korchemsky, Gregory P (Saclay) ; Sokatchev, Emery (Annecy, LAPTH ; CERN ; Inst. U. de France)
We describe a new approach to computing the chiral part of correlation functions of stress-tensor supermultiplets in N=4 SYM that relies on symmetries, analytic properties and the structure of the OPE only. [...]

Integrating out lattice gauge fields / Vairinhos, Helvio (ETH, Zurich (main)) ; de Forcrand, Philippe (ETH, Zurich (main) ; CERN)
The sign problem is a major obstacle to our understanding of the phase diagram of QCD at finite baryon density. Several numerical methods have been proposed to tackle this problem, but a full solution to the sign problem is still elusive. [...]
