The Long Road to Alignment: Measuring Black Hole Spin Orientation with Expanding Gravitational-Wave Datasets

Posted by klaurent MIT

Kavli Affiliate: Salvatore Vitale | Summary:Measuring the distribution of spin tilts-the angles between the spin vectors and the binary orbital angular momentum-in stellar-mass binary black holes detected by LIGO-Virgo-KAGRA would provide valuable insight into their astrophysical origins. Analyses of the 69 binary black holes detected through LIGO-Virgo-KAGRA’s third observing run yielded model-dependent conclusions, particularly regarding […]

This Time is Different: An Observability Perspective on Time Series Foundation Models

Posted by klaurent Cornell

Kavli Affiliate: Chris Xu | First 5 Authors: Ben Cohen, Ben Cohen, , , | Summary: We introduce Toto, a time series forecasting foundation model with 151 million parameters. Toto uses a modern decoder-only architecture coupled with architectural innovations designed to account for specific challenges found in multivariate observability time series data. Toto’s pre-training corpus […]

Engineering the Kondo impurity problem with alkaline-earth atom arrays

Posted by klaurent Caltech

Kavli Affiliate: Nelson Darkwah Oppong| Summary:We propose quantum simulation experiments of the Kondo impurity problem using cold alkaline-earth(-like) atoms (AEAs) in a combination of optical lattice and optical tweezer potentials. Within an ab initio model for atomic interactions in the optical potentials, we analyze hallmark signatures of the Kondo effect in a variety of observables […]

Spin Pumping into two-dimensional systems

Posted by klaurent UCAS

Kavli Affiliate: Mamoru Matsuo | Summary:In this review, we present recent theoretical developments on spin transport phenomena probed by ferromagnetic resonance (FMR) modulation in two-dimensional systems coupled to magnetic materials. We first address FMR linewidth enhancements induced by spin pumping at interfaces, emphasizing their potential as sensitive probes of superconducting pairing symmetries in two-dimensional superconductors. […]

Kavli Affiliate: Hsiaowen Chen| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:This paper studies properties of dual probabilistic frames — in particular in relation to redundancy — and introduces both approximately dual probabilistic frames and pseudo-dual probabilistic frames. We show that the canonical dual probabilistic frame is the only dual frame of pushforward type […]
