[HTML][HTML] A baby–Skyrme model with anisotropic DM interaction: Compact skyrmions revisited
F Hanada, N Sawado - Nuclear Physics B, 2023 - Elsevier
We consider a baby–Skyrme model with Dzyaloshinskii–Moriya interaction (DMI) and two
types of potential terms. The model has a close connection with the vacuum functional of …

Instanton size dependence on fermion energy spectra in a ℂP2 fermionic sigma model
Y Amari, N Sawado, S Yamamoto - Journal of Physics …, 2023 - iopscience.iop.org
Spectral flow is a fascinating behavior of fermion's energy levels that cross zero as a
parameter varies. In fermion-soliton system, it owes the topology of the soliton. We examine …
