二维热场玻色化II:大质量费米子

Two-Dimensional Thermofield Bosonization II: Massive Fermions

R. L. P. G. Amaral, L. V. Belvedere, K. D. Rothe

摘要:

在热场动力学方法中,我们考虑了有限温度下大质量自由费米子手征密度N点函数的微扰计算。无穷级数的质量参数的N-点函数计算的费米子配方和相应的微扰系列的相互作用参数的玻色化的热场配方进行了比较。因此,我们建立在热场动力学的形式等价的大质量自由费米子理论与sine-Gordon热场模型的sine-Gordon参数的特定值。我们扩展了热场玻色子化,包括大量的Thirring模型。

英文摘要:

We consider the perturbative computation of the N-point function of chiral densities of massive free fermions at finite temperature within the thermofield dynamics approach. The infinite series in the mass parameter for the N-point functions are computed in the fermionic formulation and compared with the corresponding perturbative series in the interaction parameter in the bosonized thermofield formulation. Thereby we establish in thermofield dynamics the formal equivalence of the massive free fermion theory with the sine-Gordon thermofield model for a particular value of the sine-Gordon parameter. We extend the thermofield bosonization to include the massive Thirring model.
