Revisiting fermion bound states in baby Skyrme background with Dzyaloshinskii Moriya interaction
Arvind Rajaraman, Chao-Hsiang Sheu, Alexander Stewart
In this paper, we investigate a fermion coupled to a Skyrme model in dimensions, where the Skyrmion is stabilized by the Dzyaloshinskii-Moriya and Skyrme interactions under a…

More on Classical Stability of Hopf-like Solitons of the Toroidal-Twisted type
Chao-Hsiang Sheu, Mikhail Shifman
The Faddeev-Hopf model [1] supporting Hopfions was shown to emerge in the low-energy limit of four-dimensional scalar quantum electrodynamics (QED) with two charged scalar fields […

Nonperturbative features in the Lie-algebraic Kähler sigma model with fermions
Chao-Hsiang Sheu
We investigate the trans-series structure of a quantum mechanical system originating from a Lie-algebraic Kähler sigma model with multiple right-handed chiral fermions, extending…
