Machine Learned Potential for High-Throughput Phonon Calculations of Metal-Organic Frameworks

Posted by dbos Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Alin Marin Elena, Prathami Divakar Kamath, Théo Jaffrelot Inizan, Andrew S. Rosen, Federica Zanca | Summary: Metal-organic frameworks (MOFs) are highly porous and versatile materials studied extensively for applications such as carbon capture and water harvesting. However, computing phonon-mediated properties in MOFs, like thermal expansion and […]

A Lower Mass Estimate for PSR J0348+0432 Based on CHIME/Pulsar Precision Timing

Posted by dbos MIT

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Alexander Saffer, Emmanuel Fonseca, Scott Ransom, Ingrid Stairs, Ryan Lynch | Summary: The binary pulsar J0348+0432 was previously shown to have a mass of approximately 2,${rm M_odot}$, based on the combination of radial-velocity and model-dependent mass parameters derived from high-resolution optical spectroscopy of its white-dwarf companion. […]

Robust Chiral Optical Force via Electric Dipole Interactions, Inspired by a Sea Creature

Posted by klaurent Stanford

Kavli Affiliate: Robert Cameron | Summary:Inspired by a sea creature, we identify a robust chiral optical force that can be several orders of magnitude stronger than others proposed to date, pushing the opposite enantiomers of orientated chiral molecules towards regions of orthogonal linear rather than circular polarization in an optical field via electric dipole interactions.
