The smooth torus orbit closures in the Grassmannians
Masashi Noji, Kazuaki Ogiwara
It is known that for the natural algebraic torus actions on the Grassmannians, the closures of torus orbits are toric varieties, and that these toric varieties are smooth if and on…
Charge Screened Nontopological Solitons in a Spontaneously Broken U(1) Gauge Theory
Hideki Ishihara, Tatsuya Ogawa
We construct, numerically, stationary and spherically symmetric nontopological soliton solutions in the system composed of a complex scalar field, a U(1) gauge field, and a complex…
Dynamics of logarithmic negativity and mutual information in smooth quenches
Hiroyuki Fujita, Mitsuhiro Nishida, Masahiro Nozaki +1
In this paper, we study how quantum correlation between subsystems changes in time by investigating time evolution of mutual information and logarithmic negativity in two protocols…
Measurements of branching fraction and direct asymmetry in and a search for
The Belle Collaboration, A. B. Kaliyar, P. Behera +197
We study charmless hadronic decays of charged mesons to the final states and using a data sample that cont…
The volume polynomial of regular semisimple Hessenberg varieties and the Gelfand-Zetlin polytope
Megumi Harada, Tatsuya Horiguchi, Mikiya Masuda +1
Regular semisimple Hessenberg varieties are subvarieties of the flag variety arising naturally in the intersection of geometry, representation theory,…
Periodic three-body orbits in the Coulomb potential
Marija Šindik, Ayumu Sugita, Milovan Šuvakov +1
We numerically discovered around 100 distinct nonrelativistic collisionless periodic three-body orbits in the Coulomb potential in vacuo, with vanishing angular momentum, for equal…
