New approach to the non-perturbative physics

TL;DR

This paper introduces a novel approach to understanding non-perturbative vacuum properties through quantum fluctuations around classical backgrounds, validated within two-dimensional sigma models.

Contribution

It presents a new method for describing non-perturbative vacuum properties using quantum fluctuations, with validation in sigma models.

Findings

Vacuum properties are described by quantum fluctuations around classical backgrounds.

The vacuum state was constructed and verified in two-dimensional sigma models.

Abstract

It was shown that the non-perturbative properties of the vacuum are described by the quantum fluctuations around the classical background with zero canonical momentum. The vacuum state has been built and checked in the framework of the sigma models in two dimentions.
