标题： Massive Quantum Vortex Excitations in a Pure Gauge Abelian Theory in 2+1D

摘要： 我们引入并研究了一种在2+1D中的纯规范阿贝尔理论，其中激发谱中存在质量量子涡旋态。 该理论可以在大正则系综中映射到具有对数相互作用的点粒子三维气体。 我们声称该理论是Sine-Gordon在2+1D的类比，质量涡旋是Sine-Gordon孤子的对应物。 我们表明存在一种类似希格斯场真空期望值的对称性破缺序参数。 显示英文摘要

摘要： We introduce and study a pure gauge abelian theory in 2+1D in which massive quantum vortex states do exist in the spectrum of excitations. This theory can be mapped in a three dimensional gas of point particles with a logarithmic interaction, in the grand-canonical ensemble. We claim that this theory is the 2+1D analog of the Sine-Gordon, the massive vortices being the counterparts of Sine-Gordon solitons. We show that a symmetry breaking, order parameter, similar to the vacuum expectation value of a Higgs field does exist.
