对偶Chern-Simons Higgs模型中的涡旋凝聚

Vortex Condensation in the Dual Chern-Simons Higgs Model

Rudnei O. Ramos, J. F. Medeiros Neto

摘要:

非平凡的真空(拓扑)激发,更具体地说,涡旋配置的自对偶陈-西蒙斯-希格斯模型,功能配分函数的贡献被认为是。通过使用对偶变换,我们得到了一个表示的配分函数,其中明确的涡旋自由度耦合到一个对偶规范场。通过匹配所获得的行动的场论的旋涡,在存在的旋涡激励的模型的物理特性进行了研究。在这个场论的自对偶陈-西蒙斯希格斯模型中的涡旋,我们确定的位置的临界值的陈-西蒙斯参数低于该涡旋凝聚可以发生在系统中。同时考虑了自能量子修正对旋涡场的影响。

英文摘要:

The contribution of nontrivial vacuum (topological) excitations, more specifically vortex configurations of the self-dual Chern-Simons-Higgs model, to the functional partition function is considered. By using a duality transformation, we arrive at a representation of the partition function in terms of which explicit vortex degrees of freedom are coupled to a dual gauge field. By matching the obtained action to a field theory for the vortices, the physical properties of the model in the presence of vortex excitations are then studied. In terms of this field theory for vortices in the self-dual Chern-Simons Higgs model, we determine the location of the critical value for the Chern-Simons parameter below which vortex condensation can happen in the system. The effects of self-energy quantum corrections to the vortex field are also considered.
