Collisional dynamics of polaronic clouds immersed in a Fermi sea
Hiroyuki Tajima, Junichi Takahashi, Eiji Nakano +1
We propose a new protocol to examine many-polaron properties in a cold atom experiment. Initially, polaronic clouds are prepared around the opposite edges of a majority gas cloud.…
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…
Spin polarizations under a pseudovector interaction between quarks with the Kobayashi-Maskawa-'t Hooft term in high density quark matter
M. Morimoto, Y. Tsue, J. da Providencia +2
A possibility of a quark spin polarization originated from a pseudovector condensate is investigated in the three-flavor Nambu-Jona-Lasinio model with the Kobayashi-Maskawa-'t Hoof…
Confinement-Deconfinement Crossover in the Lattice Model
Toshiaki Fujimori, Etsuko Itou, Tatsuhiro Misumi +2
The sigma model at finite temperature is studied using lattice Monte Carlo simulations on with radii and , respectively,…
Astrophysical implications of double-layer torsional oscillations in a neutron star crust as a lasagna sandwich
Hajime Sotani, Kei Iida, Kazuhiro Oyamatsu
In the crust of a neutron star, global torsional oscillations could occur in two elastic layers. The outer and inner layers are composed of spherical and cylindrical nuclei and of…
Search for Ultra-High-Energy Neutrinos with the Telescope Array Surface Detector
R. U. Abbasi, M. Abe, T. Abu-Zayyad +133
We present an upper limit on the flux of ultra-high-energy down-going neutrinos for $E > 10^{18}\ \mbox{eV}$ derived with the nine years of data collected by the Telescope Array su…
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 spherical trap potentials: Spatial structure and quantum depletion
Junichi Takahashi, Ryosuke Imai, Eiji Nakano +1
We investigate how the presence of a localized impurity in a Bose-Einstein condensate of trapped cold atoms that interact with each other weakly and repulsively affects the profile…
Search for point sources of ultra-high energy photons with the Telescope Array surface detector
Telescope Array Collaboration, R. U. Abbasi, M. Abe +135
The surface detector (SD) of the Telescope Array (TA) experiment allows one to indirectly detect photons with energies of order eV and higher and to separate photons from…
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…
