Liang Wu,Liang Wu,Shreyas Patankar,Shreyas Patankar,Takahiro Morimoto,Nityan Nair,Eric Thewalt,Eric Thewalt,A. Little,A. Little,James Analytis,James Analytis,Joel E. Moore,Joel E. Moore,Joseph Orenstein,Joseph Orenstein +15 more
TL;DR: In this paper, an optical second-harmonic generation study of a series of transition metal monopnictide Weyl semimetals reveals a giant, anisotropic nonlinear optical response in these systems.
Journal ArticleDOI

TL;DR: The first observation of the magneto-optical Kerr effect in an AF metal is reported, finding that the non-collinear AF metal Mn3Sn exhibits a large zero-field Kerr rotation angle of 20 mdeg at room temperature, comparable to ferromagnetic metals.

Journal ArticleDOI
Pervasive distribution of polyester fibres in the Arctic Ocean is driven by Atlantic inputs

TL;DR: In this article, the authors quantify and characterise microplastics across the North Pole, finding that synthetic fibers like polyester are dominant and likely sourced from the Atlantic Ocean, with an east-to-west shift in infra-red signatures pointing to a potential weathering of fibres away from source.
Journal ArticleDOI

TL;DR: In this paper, optical absorption in the zigzag antiferromagnet was measured as a function of temperature, magnetic field, and photon energy in the range of 0.3 to 8.3 meV using terahertz spectroscopy.
