圆上Sine-Gordon孤子的量子化:半经典与精确结果

Quantization of Sine-Gordon solitons on the circle: semiclassical vs. exact results

Michael Pawellek

摘要:

研究了周期和反周期边界条件下圆上sine-Gordon孤子的半经典量子化。利用积分表象中的zeta函数正则化方法确定了孤子质量的单圈量子修正。我们比较了半经典的结果与精确的数值计算在文献中,并找到很好的协议,即使在平原半经典制度。

英文摘要:

We consider the semiclassical quantization of sine-Gordon solitons on the circle with periodic and anti-periodic boundary conditions. The 1-loop quantum corrections to the mass of the solitons are determined using zeta function regularization in the integral representation. We compare the semiclassical results with exact numerical calculations in the literature and find excellent agreement even outside the plain semiclassical regime.
