Kavli Affiliate: Robert Cameron | Summary:Inspired by a sea creature, we identify a robust chiral optical force that can be several orders of magnitude stronger than others proposed to date, pushing the opposite enantiomers of orientated chiral molecules towards regions of orthogonal linear rather than circular polarization in an optical field via electric dipole interactions. […]
Kavli Affiliate: Gordan Krnjaic | Summary:If primordial black holes (PBH) are present in the early universe, their contribution to the energy budget grows relative to that of radiation and generically becomes dominant unless the initial abundance is exponentially small. This black hole domination scenario is largely unconstrained for PBHs with masses $lesssim 10^9,mathrmg$, which evaporate […]

Demeter, Tamara Vanderwal, Deanna J. Greene and Signe L. Bray | Summary: functional connectivity (FC) measurements are important for robust and reproducible findings, yet pediatric functional magnetic […]
Kavli Affiliate: Mikhail Kapranov | Summary:For a complex reductive Lie algebra $mathfrakg$ with Cartan subalgebra $mathfrakh$ and Weyl group $W$ we consider the category $textPerv(W backslash mathfrakh)$ of perverse sheaves on $W backslash mathfrakh$ smooth w.r.t. the natural stratification. We construct a category $boldsymbolmathcalC$ such that $textPerv(Wbackslash mathfrakh)$ is identified with the category of functors […]
Kavli Affiliate: Shawn Henderson | Summary:The Simons Observatory (SO) is a cosmic microwave background (CMB) survey experiment located in the Atacama Desert in Chile at an elevation of 5200 meters, nominally consisting of an array of three 0.42-meter small aperture telescopes (SATs) and one 6-meter large aperture telescope (LAT). SO will make accurate measurements of […]
Kavli Affiliate: Fukun Liu| Summary: Quasiperiodic eruptions (QPEs) are a novel class of transients recently discovered in a few extragalactic nuclei. It has been suggested that a QPE can be produced by a main-sequence star undergoing repeated partial disruptions by the tidal field of a supermassive black hole (SMBH) immediately after getting captured on a […]

Kavli Affiliate: Zheng Zhu | First 5 Authors: Bo Zhao, Jingyu Zhao, Zheng Zhu, Jian Wu, Zheng Liu | Summary: We propose to expand the territory of density functional theory to strongly correlated electrons by reformulating the Kohn-Sham scheme in the representation of fractionalized particles. We call it the “KS* scheme.” Using inhomogeneous $t$-$J$ chains […]
