Skyrmions and pion stars in the gauged Einstein-Skyrme model
R. Kirichenkov, J. Kunz, Nobuyuki Sawado +1
We consider topological and non-topological regular soliton solutions in the Einstein-Maxwell-Skyrme theory. We analyze the properties of these solutions and determine their domain…
Gauged compact -balls and -shells in a multi-component model
P. Klimas, L. C. Kubaski, N. Sawado +1
We study a multicomponent model's scalar electrodynamics. The model contains -balls and -shells, which are nontopological compact solitons with time dependency $e^{iωt…
Harmonic Oscillator with a Step and its Isospectral Properties
Yuta Nasuda, Nobuyuki Sawado
We investigate the one-dimensional Schrödinger equation for a harmonic oscillator with a finite jump at the origin. The solution is constructed by employing the ordinary matchi…
A baby--Skyrme model with anisotropic DM interaction: Compact skyrmions revisited
Funa Hanada, Nobuyuki Sawado
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 ferm…
