Topological Charge Asymmetry in a Skyrmion-Fermion Coupled System
Yuki Amari, Nobuyuki Sawado, Shintaro Yamamoto
Topology plays a central role in classifying solitonic configurations in field theories, providing robustness and a nonperturbative label, the so-called topological charge . In…
Skyrmion with Fermion Backreaction
Yuki Amari, Nobuyuki Sawado, Shintaro Yamamoto
When fermions interact with a topological soliton, they localize on the soliton. In studies of such systems, solitons are often treated as fixed background fields, and the backreac…
Phase Boundary of Nuclear Matter in Magnetic Field
Yuki Amari, Muneto Nitta, Zebin Qiu
Nuclear matter with a strong magnetic field is prevalent inside neutron stars and heavy-ion collisions. In a sufficiently large magnetic field the ground state is either a chiral s…
Glueballonia as Hopfions
Yuki Amari, Muneto Nitta, Chihiro Sasaki +3
We work out the Hopfion description of glueballs by inclusively comparing the energy spectra obtained by quantizing Hopfions with experimental data and lattice QCD. Identifying a H…
Domain-wall Skyrmion phase of QCD in magnetic field: Gauge field dynamics
Yuki Amari, Minoru Eto, Muneto Nitta
The ground state of QCD in sufficiently strong magnetic field at finite baryon density is an inhomogeneous state consisting of an array of solitons, called the chiral soliton latti…
Skyrmion crystal phase on a magnetic domain wall in chiral magnets
Yuki Amari, Muneto Nitta
We study a magnetic domain wall in the ferromagnetic phase in chiral magnets in two dimensions with an in-plane easy-axis anisotropy and an out-of-plane Zeeman magnetic field, and…
Isolated Skyrmions in the nonlinear -model with a Dzyaloshinskii-Moriya type interaction
Yutaka Akagi, Yuki Amari, Nobuyuki Sawado +1
We study two dimensional soliton solutions in the nonlinear -model with a Dzyaloshinskii-Moriya type interaction. First, we derive such a model as a continuous limit of t…
Statistical nature of Skyrme-Faddeev models in dimensions and normalizable fermions
Yuki Amari, Masaya Iida, Nobuyuki Sawado
The Skyrme-Faddeev model has planar soliton solutions with target space . An Abelian Chern-Simons term (the Hopf term) in the Lagrangian of the model plays a crucial…
Knot Solitons: Hopfions in the Skyrme-Faddeev-Niemi model
Yuki Amari, Nobuyuki Sawado
We discuss the existence of knot solitons (Hopfions) in a Skryme-Faddeev-Niemi-type model on the target space , which can be viewed as an effective theory of both the…
Self-Dual Skyrmions on the Spheres
Y. Amari, L. A. Ferreira
We construct self-dual sectors for scalar field theories on a -dimensional Minkowski space-time with target space being the -dimensional sphere . The constr…
