Observation of a Dirac nodal line in AlB2

Posted by klaurent July 4, 2018Tokyo

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 […]

Energy Loss Due to Defect Formation from $^{206}$Pb Recoils in SuperCDMS Germanium Detectors

Posted by dbos May 25, 2018Stanford

Kavli Affiliate: Paul Brink | First 5 Authors: Robert Agnese, Taylor Aralis, Tsuguo Aramaki, Isaac Arnquist, Elham Azadbakht | Summary: The Super Cryogenic Dark Matter Search experiment (SuperCDMS) at the Soudan Underground Laboratory studied energy loss associated with Frenkel defect formation in germanium crystals at mK temperatures using in situ $^{210}$Pb sources. We examine the […]

Concerns about Modelling of the EDGES Data

Posted by klaurent May 3, 2018Cambridge

Kavli Affiliate: Richard Hills | First 5 Authors: Richard Hills, Girish Kulkarni, P. Daniel Meerburg, Ewald Puchwein, | Summary: It is predicted that the spectrum of radio emission from the whole sky should show a dip arising from the action of the light from the first stars on the hydrogen atoms in the surrounding gas, […]

Pulling the Boundary into the Bulk

Posted by klaurent May 1, 2018Tokyo

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 […]

Statistical analysis of acoustic wave power and flows around solar active regions

Posted by klaurent April 20, 2018Stanford

Kavli Affiliate: Philip H. Scherrer | First 5 Authors: M. Cristina Rabello-Soares, Richard S. Bogart, Philip H. Scherrer, , | Summary: We analyze the effect of a sunspot in its quiet surroundings applying a helioseismic technique on almost three years of Helioseismic and Magnetic Imager (HMI) observations obtained during solar cycle 24 to further study […]

Defining Pathway Assembly and Exploring its Applications

Posted by klaurent April 19, 2018Stanford

Kavli Affiliate: Stuart Marshall | First 5 Authors: Alastair Murray, Stuart Marshall, Leroy Cronin, , | Summary: How do we estimate the probability of an abundant objects’ formation, with minimal context or assumption about is origin? To explore this we have previously introduced the concept of pathway assembly (as pathway complexity), in a graph based […]
