Universal Aspects of Deconfinement in 2+1 Dimensions

Lorenz von Smekal, Sam R Edwards, Nils Strodthoff

摘要:

N <= 4的2+1维纯SU(N)规范理论是将标度和普适性这一强有力的工具应用于有限温度下的退禁闭跃迁的候选者。相应的二维q态Potts模型(q <= 4)具有二阶相变,我们可以利用许多精确的结果得到精确的临界耦合,相变温度,临界指数,以及连续弦张力在相变附近的主导行为,以及它的对偶项.因此,二维自旋模型的自对偶性反映在类空涡旋和限制电通量之间的对偶性。我们还讨论了在考虑分数荷夸克的电磁相互作用时,中心对称性和相应的涡旋与全QCD禁闭的关系。

英文摘要:

The 2+1 dimensional pure SU(N) gauge theories with N <= 4 are candidates for applying the powerful tools of scaling and universality to their deconfinement transitions at finite temperature. The corresponding 2 dimensional q-state Potts models with q <= 4 have 2nd order transitions, and we can exploit many exact results to obtain accurate critical couplings, transition temperatures, critical exponents, and the leading behavior of the continuum string tension near the phase transition on one side, together with its dual on the other. Thereby, the self-duality of the 2d spin models is reflected in a duality between spacelike vortices and confining electric fluxes. We also discuss the relevance of center symmetry and the corresponding vortices for confinement in full QCD when the electromagnetic interactions of fractionally charged quarks are included.
