Kavli Affiliate: Tomiyoshi Haruyama | First 5 Authors: The J-Parc Ucn Taskforce, :, Tomokazu Aso, Masatoshi Futakawa, Tomiyoshi Haruyama | Summary: Discussions in the taskforce meetings in the period of Jan.-Mar. 2009 on the technical possibility of the ultracold neutron (UCN) source at the Japan Proton Accelerator Research Complex (J-PARC) is summarized. | Search Query: […]
Kavli Affiliate: Tomiyoshi Haruyama | First 5 Authors: Takayuki Tomaru, Masao Tokunari, Kazuaki Kuroda, Takashi Uchiyama, Akira Okutomi | Summary: A large heat load caused by thermal radiation through a metal shield pipe was observed in a cooling test of a cryostat for a prototype of a cryogenic interferometric gravitational wave detector. The heat load […]
Kavli Affiliate: Todor E. Milanov | First 5 Authors: Todor E. Milanov, Hsian-Hua Tseng, , , | Summary: Let $CP^1_{k,m}$ be the orbifold structure on $CP^1$ obtained via uniformizing the neighborhoods of 0 and $infty$ respectively by $zmapsto z^k$ and $wmapsto w^m.$ The diagonal action of the torus on the projective line induces naturally an […]
Kavli Affiliate: Todor E. Milanov | First 5 Authors: Todor E. Milanov, Hsian-Hua Tseng, , , | Summary: Let $M_{k,m}$ be the space of Laurent polynomials in one variable $x^k + t_1 x^{k-1}+… t_{k+m}x^{-m},$ where $k,mgeq 1$ are fixed integers and $t_{k+m}neq 0$. According to B. Dubrovin cite{D}, $M_{k,m}$ can be equipped with a semi-simple […]
Kavli Affiliate: Todor E. Milanov | First 5 Authors: Todor E. Milanov, , , , | Summary: The ancestor Gromov–Witten invariants of a compact {Kahler} manifold $X$ can be organized in a generating function called the total ancestor potential of $X$. In this paper, we construct Hirota Quadratic Equations (HQE shortly) for the total ancestor […]
Kavli Affiliate: Yukari Ito | First 5 Authors: Yukari Ito, , , , | Summary: There are many generalizations of the McKay correspondence for higher dimensional Gorenstein quotient singularities and there are some applications to compute the topological invariants today. But some of the invariants are completely different from the classical invariants, in particular for […]
Kavli Affiliate: Shigetaka Moriyama | First 5 Authors: Makoto Minowa, Shigetaka Moriyama, Yoshizumi Inoue, Toshio Namba, Yuko Takasu | Summary: A preliminary result of the solar axion search experiment at the University of Tokyo is presented. We searched for axions which could be produced in the solar core by exploiting the axion helioscope. The helioscope […]
Kavli Affiliate: Shigetaka Moriyama | First 5 Authors: Shigetaka Moriyama, , , , | Summary: An experimental method is introduced to search for almost monochromatic solar axions. In this method, we can search for solar axions by exploiting the axion-quark coupling, not relying on the axion-photon coupling at all. A recent experimental result of Krv […]
