标题： Fuzzy spheres at finite temperature supported by Wilson lines

摘要： 我们研究在有限温度和弱耦合下SU(N)xSU(N+M) Klebanov-Strassler理论中模糊球真空解的命运。我们发现热效应将S^2半径——在T=0时的一个模数——推向消失的大小。然后我们表明，通过添加一个时间方向的威尔逊线来稳定模糊球，该威尔逊线可以与背景U(1)规范场相关，该场可以与重子数或R对称性相关。因此，在对KS理论进行全局对称性的背景规范场变形后，我们在弱耦合下发现了一种打破重子数对称性的相，并且该相在有限温度下仍然存在。 显示英文摘要

摘要： We study the fate of the fuzzy sphere vacuum solutions in the SU(N)xSU(N+M) Klebanov-Strassler theory at finite temperature and at weak coupling. We find that thermal effects push the S^2 radius --a modulus at T=0-- towards vanishing size. We then show that the fuzzy sphere can be stabilized by adding a temporal Wilson line for a background U(1) gauge field, which can be associated with either the baryonic or the R-symmetry. Thus, upon deforming the KS theory with a background gauge field for a global symmetry, we find a phase of broken baryonic symmetry at weak coupling surviving at finite temperature.
