Observation of a Dirac nodal line in AlB2

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 […]

Pulling the Boundary into the Bulk

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 […]

High-speed X-ray imaging spectroscopy system with Zynq SoC for solar observations

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 […]

Hamiltonian approach to 2nd order gauge invariant cosmological perturbations

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 […]

Ring objects in the equivariant derived Satake category arising from Coulomb branches (with an appendix by Gus Lonergan)

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 […]

A pair of Calabi-Yau manifolds from a two parameter non-Abelian gauged linear sigma model

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 […]
