“Topological Fluctuations and Mass Gap of Yang-Mills Theory”
The Yang-Mills mass gap is a long-standing problem in theoretical physics, and many
attempts have been made in order to address this problem. In this talk, I will present our
recent work on the quantum Yang-Mills theory in the 3- and 4-dimensional Euclidean
spaces, which may provide us with some new ideas and help us understand the vacuum
structure of quantum Yang-Mills theory. In the first half of the talk, I will discuss a new
way of finding the classical solutions to Yang-Mills theory with nontrivial topologies.
Based on this discussion, in the second half we will see that some symmetry-allowed
fluctuations can be turned on, which eventually leads to a new perspective of the vacuum
structure of quantum Yang-Mills theory and can possibly help us resolve the mass gap
problem. This talk is based the joint work 1605.08425 with Y. Qian.
