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…

Multipolar boson stars: macroscopic Bose-Einstein condensates akin to hydrogen orbitals
C. A. R. Herdeiro, J. Kunz, I. Perapechka +2
Boson stars are often described as macroscopic Bose-Einstein condensates. By accommodating large numbers of bosons in the same quantum state, they materialize macroscopically the i…
