Self-closeness numbers of finite cell complexes
Nobuyuki Oda, Toshihiro Yamaguchi
We reformulate the inequalities among self-closeness numbers of spaces in cofibrations making use of homology dimension and show that the self-closeness number of a space is less t…
Two-colour QCD phases and the topology at low temperature and high density
Kei Iida, Etsuko Itou, Tong-Gyu Lee
We delineate equilibrium phase structure and topological charge distribution of dense two-colour QCD at low temperature by using a lattice simulation with two-flavour Wilson fermio…
The Western Bulge of 162173 Ryugu Formed as a Result of a Rotationally Driven Deformation Process
Masatoshi Hirabayashi, Eri Tatsumi, Hideaki Miyamoto +26
162173 Ryugu, the target of Hayabusa2, has a round shape with an equatorial ridge, which is known as a spinning top-shape. A strong centrifugal force is a likely contributor to Ryu…
Bose polaron in spherically symmetric trap potentials: Ground states with zero and lower angular momenta
Kano Watanabe, Eiji Nakano, Hiroyuki Yabu
Single-atomic impurities immersed in a dilute Bose gas in the spherically symmetric harmonic trap potentials are studied at zero temperature. In order to find the ground state of t…
