Phonon-mediated electron attraction in SrTiO$_3$ via the generalized Fröhlich and deformation potential mechanisms

Posted by dbos January 28, 2025February 10, 2025Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Norm M. Tubman, Christopher J. N. Coveney, Chih-En Hsu, Andres Montoya-Castillo, Marina R. Filip | Summary: Superconductivity in doped SrTiO$_3$ was discovered in 1964, the first superconducting transition observed in a doped semiconductor. However, the mechanism behind electron pairing in SrTiO$_3$ remains a subject of debate. […]

A Neural Network Model for the Cosmic Dispersion Measure in the CAMELS Simulations

Posted by klaurent January 28, 2025Tokyo

Kavli Affiliate: Khee-Gan Lee | Summary:The probability distribution, $p(mathrmDM)$ of cosmic dispersion measures (DM) measured in fast radio bursts (FRBs) encodes information about both cosmology and galaxy feedback. In this work, we study the effect of feedback parameters in the $p(mathrmDM)$ calculated from the full Latin Hypercube of parameters sampled by the CAMELS hydrodynamical simulation […]

BASS XLV: Quantifying AGN Selection Effects in the Chandra COSMOS-Legacy Survey with BASS

Posted by dbos January 28, 2025February 10, 2025Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Yarone M. Tokayer, Michael J. Koss, C. Megan Urry, Priyamvada Natarajan, Richard Mushotzky | Summary: Deep extragalactic X-ray surveys, such as the Chandra COSMOS-Legacy field (CCLS), are prone to be biased against active galactic nuclei (AGN) with high column densities due to their lower count rates at […]

Spin frustration and unconventional spin twisting state in van der Waals ferromagnet/antiferromagnet heterostructures

Posted by klaurent January 28, 2025Berkeley

Kavli Affiliate: Michael Crommie | Summary:Atomically flat surfaces of van der Waals (vdW) materials pave an avenue for addressing a long-standing fundamental issue of how a perfectly compensated antiferromagnet (AFM) surface frustrates a ferromagnetic (FM) overlayer in FM/AFM heterostructures. By revealing the AFM and FM spin structures separately in vdW Fe5GeTe2/NiPS3 heterostructures, we find that […]
