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 […]

Kavli Affiliate: Toshitake Kohno | First 5 Authors: Louis Funar, Toshitake Kohno, , , | Summary: We prove that, except for a few explicit roots of unity, the quantum image of any Johnson subgroup of the mapping class group contains an explicit free non-abelian subgroup. | Search Query: ArXiv Query: search_query=au:”Toshitake Kohno”&id_list=&start=0&max_results=3 Read More

Kavli Affiliate: Yukari Ito | First 5 Authors: Akira Ishii, Yukari Ito, Álvaro Nolla de Celis, , | Summary: In this paper we consider the iterated G-equivariant Hilbert scheme G/N-Hilb(N-Hilb) and prove that G/N-Hilb(N-Hilb(C^3)) is a crepant resolution of C^3/G isomorphic to the moduli space of theta-stable representations of the McKay quiver for certain stability […]

Kavli Affiliate: Atsushi Yagishita | First 5 Authors: Kentaro Tanaka, Atsushi Yagishita, Masami Miyakawa, , | Summary: For a given statistical model, it often happens that it is necessary to intervene the model to reduce the variances of the output variables. In structural equation models, this can be done by changing the values of the […]
