Kavli Affiliate: Kentaro Hori | First 5 Authors: Daichi Takane, Seigo Souma, Kosuke Nakayama, Takechika Nakamura, Hikaru Oinuma | Summary: We have performed angle-resolved photoemission spectroscopy of AlB2 which is isostructural to high-temperature superconductor MgB2. Using soft-x-ray photons, we accurately determined the three-dimensional bulk band structure and found a highly anisotropic Dirac-cone band at the […]
Kavli Affiliate: Mark Hartz | First 5 Authors: Yoshi Uchida, Mark Hartz, R. Phillip Litchfield, Callum Wilkinson, Asher Kaboth | Summary: The presentations, discussions and findings from the inaugural `PhyStat-$nu$’ workshop held at the Kavli Institute for the Physics and Mathematics of the Universe (IPMU) near Tokyo in 2016 are described. PhyStat-$nu$ was the first […]
Kavli Affiliate: Yasunori Nomura | First 5 Authors: Yasunori Nomura, Pratik Rath, Nico Salzetta, , | Summary: Motivated by the ability to consistently apply the Ryu-Takayanagi prescription for general convex surfaces and the relationship between entanglement and geometry in tensor networks, we introduce a novel, covariant bulk object – the holographic slice. The holographic slice […]
Kavli Affiliate: Mikhail Kapranov | First 5 Authors: Michael Finkelberg, Mikhail Kapranov, Vadim Schechtman, , | Summary: We consider the category of perverse sheaves on a complex vector space smooth with respect to a stratification given by an arrangement of hyperplanes with real equations. As shown in an earlier wotk of two of the authors, […]
Kavli Affiliate: Tadashi Orita | First 5 Authors: Shin-nosuke Ishikawa, Tadayuki Takahashi, Shin Watanabe, Noriyuki Narukage, Satoshi Miyazaki | Summary: We have developed a system combining a back-illuminated Complementary-Metal-Oxide-Semiconductor (CMOS) imaging sensor and Xilinx Zynq System-on-Chip (SoC) device for a soft X-ray (0.5-10 keV) imaging spectroscopy observation of the Sun to investigate the dynamics of […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Guillem Domènech, Misao Sasaki, , , | Summary: In view of growing interest in tensor modes and their possible detection, we clarify the definition of tensor modes up to 2nd order in perturbation theory within the Hamiltonian formalism. Like in gauge theory, in cosmology the Hamiltonian is […]
Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Alexander Braverman, Michael Finkelberg, Hiraku Nakajima, , | Summary: This is the second companion paper of arXiv:1601.03586. We consider the morphism from the variety of triples introduced in arXiv:1601.03586 to the affine Grassmannian. The direct image of the dualizing complex is a ring object in the equivariant […]
Kavli Affiliate: Yukari Ito | First 5 Authors: Alastair Craw, Yukari Ito, Joseph Karmazyn, , | Summary: Given a scheme $Y$ equipped with a collection of globally generated vector bundles $E_1, dots, E_n$, we study the universal morphism from $Y$ to a fine moduli space $mathcal{M}(E)$ of cyclic modules over the endomorphism algebra of $E:=mathcal{O}_Yoplus […]
Kavli Affiliate: Kentaro Hori | First 5 Authors: Kentaro Hori, Johanna Knapp, , , | Summary: We construct and study a two parameter gauged linear sigma model with gauge group $(U(1)^2times O(2))/{mathbb Z}_2$ that has a dual model with gauge group $(U(1)^2times SO(4))/{mathbb Z}_2$. The model has two geometric phases, three hybrid phases and one […]
Kavli Affiliate: Naoyuki Tamura | First 5 Authors: Akifumi Seko, Kouji Ohta, Kiyoto Yabe, Bunyo Hatsukade, Masayuki Akiyama | Summary: We constrain the rate of gas inflow into and outflow from a main-sequence star-forming galaxy at z~1.4 by fitting a simple analytic model for the chemical evolution in a galaxy to the observational data of […]
