Collision, mechanism, and $Z_{4}$ operation among chiral and nonchiral kinks in coupled double-field $ϕ^{4}$ model

Jin-Hyung Choi, Sang-Hoon Han, Myungjun Kang +1

In this work, we investigate collision processes and their mechanism among chiral and nonchiral kinks in the coupled double-field $ϕ^{4}$ model and show that the kink collisions foll…

Electric-magnetic duality as a quantum operator and more symmetries of $U (1)$ gauge theory

Hobin Lee, Sanghoon Han, Hyein Yoon +2

We promote the Noether charge of the electric-magnetic duality symmetry of $U (1)$ gauge theory, " $G$ " to a quantum operator. We construct ladder operators, $D_{(\pm) a}^{†} (k)$ …
