Cosmological constraints from weak lensing scattering transform using HSC Y1 data

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Sihao Cheng, Gabriela A. Marques, Daniela Grandón, Leander Thiele, Masato Shirasaki | Summary: As weak lensing surveys go deeper, there is an increasing need for reliable characterization of non-Gaussian structures at small angular scales. Here we present the first cosmological constraints with weak lensing scattering transform, a […]

Double Magnon-Roton Excitations in the Triangular-Lattice Spin Supersolid

Posted by dbos UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Yuan Gao, Chuandi Zhang, Junsen Xiang, Dehong Yu, Xingye Lu | Summary: Supersolid is an exotic quantum state of matter that spontaneously hosts the features of both solid and superfluid, which breaks the translation and U(1) gauge symmetries. Here we study the spin dynamics in the triangular-lattice […]

Jamming memory into acoustically trained dense suspensions under shear

Posted by klaurent Cornell

Kavli Affiliate: Itai Cohen | Summary:Systems driven far from equilibrium often retain structural memories of their processing history. This memory has, in some cases, been shown to dramatically alter the material response. For example, work hardening in crystalline metals can alter the hardness, yield strength, and tensile strength to prevent catastrophic failure. Whether memory of […]

A Ramsey Neutron-Beam Experiment to Search for Ultralight Axion Dark Matter at the ESS

Posted by klaurent Tokyo

Kavli Affiliate: Yevgeny Stadnik | Summary:High-intensity neutron beams, such as those available at the European Spallation Source (ESS), provide new opportunities for fundamental discoveries. Here we discuss a novel Ramsey neutron-beam experiment to search for ultralight axion dark matter through its coupling to neutron spins, which would cause the neutron spins to rotate about the […]
