Optical design of diffraction-limited X-ray telescopes

Posted by klaurent MIT

Kavli Affiliate: Ralf K. Heilmann | First 5 Authors: Brandon D. Chalifoux, Ralf K. Heilmann, Herman L. Marshall, Mark L. Schattenburg, | Summary: Astronomical imaging with micro-arcsecond ($mu$as) angular resolution could enable breakthrough scientific discoveries. Previously-proposed $mu$as X-ray imager designs have been interferometers with limited effective collecting area. Here we describe X-ray telescopes achieving diffraction-limited […]

SENSEI: Direct-Detection Results on sub-GeV Dark Matter from a New Skipper-CCD

Posted by klaurent Chicago

Kavli Affiliate: Michael Crisler | Summary:We present the first direct-detection search for eV-to-GeV dark matter using a new ~2-gram high-resistivity Skipper-CCD from a dedicated fabrication batch that was optimized for dark-matter searches. Using 24 days of data acquired in the MINOS cavern at the Fermi National Accelerator Laboratory, we measure the lowest rates in silicon […]

Fingerprints of the Strong Interaction between Monolayer MoS2 and Gold

Posted by klaurent Cornell

Kavli Affiliate: Hector D. Abruna | Summary:Gold-mediated exfoliation of MoS2 has attracted considerable interest in the recent years. A strong interaction between MoS2 and Au facilitates preferential production of centimeter-sized monolayer MoS2 with near-unity yield and provides a heterostructure system noteworthy from a fundamental standpoint. However, little is known about the detailed nature of the […]

Atomic line defects and topological superconductivity in unconventional superconductors

Posted by dbos UCAS

Kavli Affiliate: Fuchun Zhang | First 5 Authors: Yi Zhang, Kun Jiang, Fuchun Zhang, Jian Wang, Ziqiang Wang | Summary: Topological superconductors (TSCs) are correlated quantum states with simultaneous off-diagonal long-range order and nontrivial topological invariants. They produce gapless or zero energy boundary excitations, including Majorana zero modes and chiral Majorana edge states with topologically […]

Defect CFT in the 6d (2,0) theory from M2 brane dynamics in AdS$_7 times$S$^4$

Posted by klaurent UCAS

Kavli Affiliate: Xinan Zhou | First 5 Authors: Nadav Drukker, Simone Giombi, Arkady A. Tseytlin, Xinan Zhou, | Summary: Surface operators in the 6d (2,0) theory at large $N$ have a holographic description in terms of M2 branes probing the AdS$_7 times S^4$ M-theory background. The most symmetric, 1/2-BPS, operator is defined over a planar […]
