Kavli Affiliate: Kunio Inoue | First 5 Authors: Ken-Ichi Fushimi, Hiroyasu Ejiri, Ryuta Hazama, Haruo Ikeda, Kunio Inoue | Summary: A high purity and large volume NaI(Tl) scintillator was developed to search for cosmic dark matter. The required densities of radioactive impurities (RIs) such as U-chain, Th-chain are less than a few ppt to establish […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Ofer Aharony, Yuji Tachikawa, Kiyonori Gomi, , | Summary: S-folds are generalizations of orientifolds in type IIB string theory, such that the geometric identifications are accompanied by non-trivial S-duality transformations. They were recently used by Garcia-Etxebarria and Regalado to provide the first construction of four dimensional N=3 […]

Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Alexander Braverman, Michael Finkelberg, Hiraku Nakajima, , | Summary: Consider the $3$-dimensional $mathcal N=4$ supersymmetric gauge theory associated with a compact Lie group $G_c$ and its quaternionic representation $mathbf M$. Physicists study its Coulomb branch, which is a noncompact hyper-K"ahler manifold with an $mathrm{SU}(2)$-action, possibly with singularities. […]
Kavli Affiliate: Masaki Yamashita | First 5 Authors: Masaki Yamashita, , , , | Summary: XMASS-I uses single phase liquid xenon technology for aiming at the direct detection of dark matter. The detector observes only scintillation light by 2 inch 642 PMTs which are placed in sphere shape around an active volume. With its large […]
Kavli Affiliate: Kentaro Hori | First 5 Authors: Kentaro Hori, Heeyeon Kim, Piljin Yi, , | Summary: We compute the Witten index of one-dimensional gauged linear sigma models with at least ${mathcal N}=2$ supersymmetry. In the phase where the gauge group is broken to a finite group, the index is expressed as a certain residue […]
Kavli Affiliate: Mark Vagins | First 5 Authors: LBNE Collaboration, Corey Adams, David Adams, Tarek Akiri, Tyler Alion | Summary: The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay — these mysteries at the forefront […]

Kavli Affiliate: Toshitake Kohno | First 5 Authors: Toshitake Kohno, Andrei Pajitnov, , , | Summary: Let X be a finite CW-complex, denote its fundamental group by G. Let R be an n-dimensional complex repesentation of G. Any element A of the first cohomology group of X with complex coefficients gives rise to the exponential […]
Kavli Affiliate: Tomiyoshi Haruyama | First 5 Authors: Takashi Uchiyama, Shinji Miyoki, Souichi Telada, Kazuhiro Yamamoto, Masatake Ohashi | Summary: The thermal fluctuation of mirror surfaces is the fundamental limitation for interferometric gravitational wave (GW) detectors. Here, we experimentally demonstrate for the first time a reduction in a mirror’s thermal fluctuation in a GW detector […]
