Tunable decoupling of coexisting magnetic orders in Co$_1/3$TaS$_2$

Kavli Affiliate: Linda Ye| Summary:In multiferroics, new physical responses and functionalities emerge when symmetry-distinct order parameters couple. This conventionally occurs when lattice and magnetic degrees of freedom order independently in a material. Here, we report an all-magnetic analogue of multiferroic behavior in the antiferromagnet Co$_1/3$TaS$_2$, where topological scalar spin chirality and nematicity coexist on the […]

Worlds Next Door. IV. Mapping the Late Stages of Giant Planet Evolution with a Precise Dynamical Mass and Luminosity for $ε$ Ind Ab

Kavli Affiliate: Dimitri Mawet| Summary:We present new JWST/NIRCam 4-5 $μ$m (F410M, F430M) and JWST/MIRI 18-25 $μ$m (F1800W, F2100W, F2550W) imaging detections of the nearby (3.6 pc) cold (275 K) gas giant exoplanet $ε$ Ind Ab. The F2550W detection of $ε$ Ind Ab constitutes the longest wavelength image of an exoplanet acquired to date. Combining three […]

Correlation between nuclear isospin asymmetry and $α$-particle preformation probability for superheavy nuclei from a Bayesian inference

Kavli Affiliate: Wei Gao| Summary:In the study of $α$ decay within the superheavy nuclear region ($Z geq 90$ and $N geq 140$), the $α$-particle preformation probability $P_α$ serves as a crucial physical quantity linking nuclear structure to decay observables. We introduce a phenomenological model incorporating the decay energy $Q_α$, mass number $A$, orbital angular momentum […]

Bayesian neural network with autoencoder for model-based description of $α$-particle preformation factor

Kavli Affiliate: Wei Gao| Summary:$α$ decay is an important probe for studying the structure of heavy and superheavy nuclei, in which the $α$-particle preformation ($P_α$) is a key physical quantity for describing decay half-lives. This work develops a hybrid framework that integrates Bayesian neural networks with autoencoder (BNN-Auto), combined with the cosh potential (CPT), to […]

Centrifugal-corrected harmonic oscillator model for spherical proton emitters

Kavli Affiliate: Wei Gao| Summary:In the present work, we propose an improved harmonic oscillator model to systematically evaluate the proton radioactivity half-lives in spherical nuclei, incorporating centrifugal potential effects. By fitting the experimental data, the centrifugal parameter $d = 0.143$ for the correction term $dl(l+1)$ and nuclear potential depth $V_0 = 62.4$ MeV are obtained. […]

Identification of the I$_10$ Donor in ZnO as a Sn–Li Complex with Large Hyperfine Interaction

Kavli Affiliate: Joseph Falson | Summary:Donor impurities in wide direct band gap semiconductors provide a promising platform for spin–photon quantum technologies by combining a donor spin qubit with optically addressable transitions. In ZnO, the shallow donor with the largest reported binding energy has long been associated with the I$_10$ bound exciton line, but its microscopic […]
