Microtextures in the Chelyabinsk impact breccia reveal the history of Phosphorus-Olivine-Assemblages in chondrites

Posted by dbos Caltech

Kavli Affiliate: Paul D. Asimow | First 5 Authors: Craig R. Walton, Ioannis Baziotis, Ana Černok, Oliver Shorttle, Paul D. Asimow | Summary: The geochemistry and textural associations of chondritic phosphate minerals can provide insights into the geological histories of parental asteroids, but the processes governing their formation and deformation remain poorly constrained. Here, we […]

Enhanced corrections near holographic entanglement transitions: a chaotic case study

Posted by dbos UCAS

Kavli Affiliate: Huajia Wang | First 5 Authors: Xi Dong, Huajia Wang, , , | Summary: Recent work found an enhanced correction to the entanglement entropy of a subsystem in a chaotic energy eigenstate. The enhanced correction appears near a phase transition in the entanglement entropy that happens when the subsystem size is half of […]

Multiband Polarimetric Imaging of HR 4796A with the Gemini Planet Imager

Posted by dbos Stanford

Kavli Affiliate: Bruce A. Macintosh | First 5 Authors: Pauline Arriaga, Michael P. Fitzgerald, Gaspard Duchêne, Paul Kalas, Maxwell A. Millar-Blanchaer | Summary: HR4796A hosts a well-studied debris disk with a long history due to its high fractional luminosity and favorable inclination lending itself well to both unresolved and resolved observations. We present new J- […]

Muons in supernovae: implications for the axion-muon coupling

Posted by dbos Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Robert Bollig, William DeRocco, Peter W. Graham, Hans-Thomas Janka, | Summary: The high temperature and electron degeneracy attained during a supernova allow for the formation of a large muon abundance within the core of the resulting proto-neutron star. If new pseudoscalar degrees of freedom have large […]
