Topochemically-engineered coexistence of charge and spin orders in intercalated endotaxial heterostructures

Posted by klaurent Berkeley, This Week: Nanoscience

Kavli Affiliate: Kwabena Bediako| Summary:Correlated electron systems that host multiple electronic orders offer routes to multifunctional quantum materials, but strong competition between these orders often prevents their coexistence. Here we show that nanoscale, metastable intercalated heterostructures can stabilize a rare combination of long-range magnetism and a commensurate charge density wave (C-CDW) order in a single […]

Black Hole-Boson Star Binaries: Gravitational Wave Signals and Tidal Disruption

Posted by klaurent Cambridge, This Week: Astrophysics

Kavli Affiliate: Ulrich Sperhake | Summary:We present a detailed, fully nonlinear study of binary systems involving one black hole and one boson star, considering the effects of both a quartic self-interaction and a solitonic potential for the scalar field. First, we show the importance of using initial data for which the boson star is in […]

A Catalog of Mid-infrared Variable Sources in the Ecliptic Poles

Posted by klaurent Peking, This Week: Astrophysics

Kavli Affiliate: Luis Ho | Summary:We construct a catalog of mid-infrared (MIR) variable sources using the multi-epoch 3.6 (W1) and 4.5 $μ$m (W2) dataset from the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) at the north and south ecliptic poles (NEP and SEP). The catalog provides well-sampled light curves that cover areas within a radius […]

The JWST Search for Earth-Luna Analogs: Upper Limits on Exomoons and Refined Ephemerides for TOI 700 d and e

Posted by klaurent MIT, This Week: Astrophysics

Kavli Affiliate: Andrew Vanderburg | Summary:While no conclusive detections of exomoons have been reported to date, planet formation theories predict that satellites should be a common outcome of the collisional dynamics in early extrasolar systems. Such satellites have the potential to unlock new avenues to learn about exoplanet systems, speaking to topics of habitability, tidal […]

Implications of low neutron star merger rates for gamma-ray bursts, r-process production and Galactic double neutron stars

Posted by klaurent Chicago, This Week: Astrophysics

Kavli Affiliate: Alexander Ji | Summary:The first multimessenger discovery of a binary neutron star (BNS) merger, GW170817, proved that such mergers can source short gamma-ray bursts (SGRBs) and produce rprocess elements. The initial merger rate from this single event in the first two observing runs of the LIGO-Virgo observatory network, $110$–$3840,mathrmGpc^-3,mathrmyr^-1$, was found to be […]

Electroweak Doublet Dark Matter for a Galactic Halo Gamma-Ray Excess

Posted by klaurent This Week: Astrophysics, Tokyo

Kavli Affiliate: Yasunori Nomura | Summary:Weakly interacting massive particles provide a well-motivated framework for dark matter, naturally reproducing the observed relic abundance through thermal freeze-out. A recent claim of an indirect-detection signal from the Galactic halo, consistent with dark matter annihilation in the mass range 400–800 GeV, motivates a reexamination of minimal models that can […]

Rank-Based Sparse Regression in Principal Components Space under Measurement Error

Posted by klaurent Peking, This Week: Astrophysics

Kavli Affiliate: Feng Long| Summary: We study high-dimensional regression in principal components space when the predictors are observed with additive measurement error and the response errors may be heavy-tailed. The starting point is the $ell_1$-penalized principal-components estimator of Song and Zou (2026), which enjoys a blessing-of-dimensionality phenomenon under predictor contamination but senstive for heavy-tailed data […]

High Dimensional Bootstrap and Asymptotic Expansion for the $k$-th Largest Coordinate

Posted by klaurent Peking, This Week: Astrophysics

Kavli Affiliate: Feng Long| Summary: We study bootstrap inference for the $k$th largest coordinate of a normalized sum of independent high-dimensional random vectors. Existing second-order theory for maxima does not directly extend to order statistics, because the event $T_n,[k]le t$ is not a rectangle and its local structure is governed by exceedance counts rather than […]

Resolutions and deformations of cyclic quotient surface singularities

Posted by klaurent Tokyo

Kavli Affiliate: Yukari Ito | Summary:In this paper, we investigate the relations among various results concerning the minimal resolution of cyclic quotient singularities of the form $mathbbC^2/G$. We refer to these as "bamboo-type" singularities, since the dual graphs of the exceptional curves in their resolutions resemble the shape of bamboo. We present classical results on […]
