Fano manifolds and stability of tangent bundles
Akihiro Kanemitsu
We determine the stability/instability of the tangent bundles of the Fano varieties in a certain class of two orbit varieties, which are classified by Pasquier in 2009. As a conseq…
Josephson Effect and Charge Distribution in Thin BiTe Topological Insulators
Martin P. Stehno, Prosper Ngabonziza, Hiroaki Myoren +1
Thin layers of topological insulator materials are quasi-two-dimensional systems featuring a complex interplay between quantum confinement and topological band structure. To unders…
Systematic study of the peak energy of the broad-band Gamma-Ray Burst
Daisuke Katsukura, Takanori Sakamoto, Makoto S. Tashiro +1
We have performed a systematic study of Gamma-Ray Bursts (GRBs), which have various values in the peak energy of the spectrum of the prompt emission, , observe…
Geodesic Folding of Tetrahedron
Seri Nishimoto, Takashi Horiyama, Tomohiro Tachi
In this work, we show the geometric properties of a family of polyhedra obtained by folding a regular tetrahedron along regular triangular grids. Each polyhedron is identified by a…
Cylinders in weak del Pezzo fibrations
Masatomo Sawahara
In this article, we shall look into the existence of vertical cylinders contained in a weak del Pezzo fibration as a generalization of the former work due to Dubouloz and Kishimoto…
Alternating knots with large boundary slope diameter
Masaharu Ishikawa, Thomas W. Mattman, Kazuya Namiki +1
We show that, for an alternating knot, the ratio of the diameter of the set of boundary slopes to the crossing number can be arbitrarily large.
Swelling of doubly magic Ca core in Ca isotopes beyond
M. Tanaka, M. Takechi, A. Homma +67
Interaction cross sections for Ca on a carbon target at 280 MeV/nucleon have been measured for the first time. The neutron number dependence of derived root-mean…
Sparse Modeling in Quantum Many-Body Problems
Junya Otsuki, Masayuki Ohzeki, Hiroshi Shinaoka +1
This review paper describes the basic concept and technical details of sparse modeling and its applications to quantum many-body problems. Sparse modeling refers to methodologies f…
Trichotomy for the reconfiguration problem of integer linear systems
Kei Kimura, Akira Suzuki
In this paper, we consider the reconfiguration problem of integer linear systems. In this problem, we are given an integer linear system and two feasible solutions $\boldsymbol…
Flat bands in twisted bilayer transition metal dichalcogenides
Zhiming Zhang, Yimeng Wang, Kenji Watanabe +4
The crystal structure of a material creates a periodic potential that electrons move through giving rise to the electronic band structure of the material. When two-dimensional mate…
Nickelate superconductors Multiorbital nature and spin freezing
Philipp Werner, Shintaro Hoshino
Superconductivity with a remarkably high has recently been found in Sr-doped NdNiO thin films. While this system bears strong similarities to the cuprates, some differenc…
Design of Resonance Ratio Control with Relative Position Information for Two-inertia System
Kenta Araake, Sho Sakaino, Toshiaki Tsuji
Two-inertia systems are prone to resonance vibrations that degrade their control performances. These unwanted vibrations can be effectively suppressed by control methods based on a…
Time Series Motion Generation Considering Long Short-Term Motion
Kazuki Fujimoto, Sho Sakaino, Toshiaki Tsuji
Various adaptive abilities are required for robots interacting with humans in daily life. It is difficult to design adaptive algorithms manually; however, by using end-to-end machi…
Imitation Learning Based on Bilateral Control for Human-Robot Cooperation
Ayumu Sasagawa, Kazuki Fujimoto, Sho Sakaino +1
Robots are required to autonomously respond to changing situations. Imitation learning is a promising candidate for achieving generalization performance, and extensive results have…
Ground-State Phases of Alternating-Bond S = 1 Diamond Chains
