Spectral flow of fermions in the ℂP2 (anti-) instanton, and the sphaleron with vanishing topological charge

Y Amari, N Sawado, S Yamamoto - Journal of High Energy Physics, 2024 - Springer
A bstract The spectral flow is ubiquitous in the physics of soliton-fermion interacting systems.
We study the spectral flows related to a continuous deformation of background soliton …
