Topology-ferrimagnetism intertwining via weak interactions in Lieb lattices

Kavli Affiliate: Long Zhang | First 5 Authors: Lei Chen, Lei Chen, , , | Summary: A common wisdom about quantum many-body systems is that emergent phases typically fall into either the Landau-Ginzburg paradigm or topological classifications. Experimentally realizing the intertwined emergence of spontaneous symmetry breaking and topological order remains challenging. Here, we present an […]

Learning decouples accuracy and reaction time for rapid decisions in a transitive inference task

Kavli Affiliate: Vincent Ferrera | Authors: Fabian A Munoz Silva, Greg Jensen, Maxwell Shinn, Yelda Alkan, John Murray, Herbert Terrace and Vincent P Ferrera | Summary: Transitive inference (TI) is a cognitive process in which decisions are guided by internal representations of abstract relationships. While the mechanisms underlying transitive learning have been well studied, the […]

EMPRESS. XV. A New Determination of the Primordial Helium Abundance Suggesting a Moderately Low $Y_mathrmP$ Value

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Hiroto Yanagisawa, Hiroto Yanagisawa, , , | Summary: We present a new constraint on the primordial helium abundance, $Y_mathrmP$, based on Subaru observations. A major source of uncertainty in previous $Y_mathrmP$ determinations is the lack of extremely metal-poor galaxies (EMPGs; $0.01-0.1Z_odot$), which have metallicities a few to […]
