The LHS 1678 System: Two Earth-Sized Transiting Planets and an Astrometric Companion Orbiting an M Dwarf Near the Convective Boundary at 20 pc

Posted by klaurent MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Michele L. Silverstein, Joshua E. Schlieder, Thomas Barclay, Benjamin J. Hord, Wei-Chun Jao | Summary: We present the TESS discovery of the LHS 1678 (TOI-696) exoplanet system, comprised of two approximately Earth-sized transiting planets and a likely astrometric brown dwarf orbiting a bright ($V_J$=12.5, $K_s$=8.3) M2 dwarf […]

What drives the scatter of local star-forming galaxies in the BPT diagrams? A Machine Learning based analysis

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Mirko Curti, Connor Hayden-Pawson, Roberto Maiolino, Francesco Belfiore, Filippo Mannucci | Summary: We investigate which physical properties are most predictive of the position of local star forming galaxies on the BPT diagrams, by means of different Machine Learning (ML) algorithms. Exploiting the large statistics from the Sloan […]

Multi-Particle Tunneling Transport at Strongly-Correlated Interfaces

Posted by klaurent UCAS

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Hiroyuki Tajima, Daigo Oue, Mamoru Matsuo, , | Summary: We elucidate the multi-particle transport of pair- and spin-tunnelings in strongly correlated interfaces. Not only usual single-particle tunneling but also interaction-induced multi-particle tunneling processes naturally arise from a conventional microscopic model without any empirical parameters, through the overlap […]

Unified Description of Tunneling Transport in Ultracold Atomic Gases

Posted by klaurent UCAS

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Hiroyuki Tajima, Daigo Oue, Mamoru Matsuo, , | Summary: We derive tunneling Hamiltonians from a microscopic model of ultracold atoms separated by an external potential barrier. Not only usual one-body tunneling but also pair- and spin-tunneling processes naturally arise from a well-known microscopic model without any empirical […]
