Kavli Affiliate: Tom Melia | Summary:We renormalize massless scalar effective field theories (EFTs) to higher loop orders and higher orders in the EFT expansion. To facilitate EFT calculations with the R* renormalization method, we construct suitable operator bases using Hilbert series and related ideas in commutative algebra and conformal representation theory, including their novel application […]

Kavli Affiliate: Leon Balents | Summary:The geometrically frustrated 3D pyrochlore lattice has been long predicted to host a quantum spin liquid, an intrinsic long-range entangled state with fractionalized excitations. To date, most proposals for pyrochlore materials have focused on quantum spin ice, a $mathrmU(1)$ quantum spin liquid whose only low energy excitations are emergent photons […]
Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Veselin B. Kostov, Brian P. Powell, Guillermo Torres, Tamas Borkovits, Saul A. Rappaport | Summary: We report the discovery of a compact, coplanar, quadruply-lined, eclipsing quadruple star system from TESS data, TIC 454140642, also known as TYC 0074-01254-1. The target was first detected in Sector 5 […]
