Non-local low energy neutral excitations in a strongly disordered triangular Mott magnet Cr$_3$Se$_2$Br$_5$

Posted by klaurent Berkeley

Kavli Affiliate: James Analytis| Summary:Understanding if low-energy excitations can remain itinerant in the presence of strong disorder remains a central challenge in frustrated quantum magnets, where disorder is generally expected to localize excitations through Anderson-like mechanisms. Here we report the emergence of charge-neutral itinerant excitations in a van der Waals compound Cr$_3$Se$_2$Br$_5$, a strongly disordered […]

Layer 6 corticothalamic neurons show diverse and dynamic responses that support a role in cortical gain control in noisy environments

Posted by dbos Hopkins

Kavli Affiliate: Patrick Kanold | Authors: Marina Cardoso de Oliveira and Patrick O Kanold | Summary: Listening in complex environments requires the enhancement of relevant sounds and suppression of irrelevant ones. Corticothalamic neurons (CTNs) in auditory cortex layer (L) 6 provide modulatory feedback to thalamic nuclei and to upper cortical layers and are thought to […]

Thermal Spin Polarization Driven by Nuclear Spin-Orbit Coupling in Neutron Star Pasta

Posted by klaurent UCAS

Kavli Affiliate: Mamoru Matsuo | Summary:We discuss anomalous spin polarization on the surface of nuclear pasta in a neutron star, driven by a nuclear spin-orbit interaction. We present an effective two-band model of surface-localized neutrons near the nuclear pasta. The central point is the emergence of a Rashba-type spin-orbit hybridization generated by the neutron–nucleus spin-orbit […]
