Instanton effects in two-dimensional scalar electrodynamics
Description
Effective Lagrangian of two-dimensional scalar electrodynamics taking account of vacuum complex structure effects in a model is determined. Multi-instanton configurations are plotted and their interaction energy is calculated. Approximation of rarefied instanton gas is plotted and on its basis effective low-energy Lagrangian containing neutral scalar and pseudoscalar fields is found. On the basis of the effective Lagrangian Green functions for the gauge-invariant operators interpolating the described scalar and pseudoscalar fields are calculated
