A Malmquist-like bias in the inferred areas of diamond caustics and consequences for inferred time delays of gravitationally lensed quasars

Posted by dbos MIT

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Derek Baldwin, Paul L. Schechter, , , | Summary: Quasars are quadruply lensed only when they lie within the diamond caustic of a lensing galaxy. This precondition produces a Malmquist-like selection effect in observed populations of quadruply lensed quasars, overestimating the true caustic area. The bias […]

Statistical mechanics model for Clifford random tensor networks and monitored quantum circuits

Posted by dbos UCSB

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Yaodong Li, Romain Vasseur, Matthew P. A. Fisher, Andreas W. W. Ludwig, | Summary: We introduce an exact mapping of Clifford (stabilizer) random tensor networks (RTNs) and monitored quantum circuits, onto a statistical mechanics model. With Haar unitaries, the fundamental degrees of freedom (‘spins’) are […]

Diving Beneath the Sea of Stellar Activity: Chromatic Radial Velocities of the Young AU Mic Planetary System

Posted by dbos MIT

Kavli Affiliate: Christopher Burke | First 5 Authors: Bryson Cale, Michael Reefe, Peter Plavchan, Angelle Tanner, Eric Gaidos | Summary: We present updated radial-velocity (RV) analyses of the AU Mic system. AU Mic is a young (22 Myr) early M dwarf known to host two transiting planets – $P_{b}sim8.46$ days, $R_{b}=4.38_{-0.18}^{+0.18} R_{oplus}$, $P_{c}sim18.86$ days, $R_{c}=3.51_{-0.16}^{+0.16} […]

In-situ non-equilibrium nanomechanics in a proton-conducting ceramic at low temperatures

Posted by dbos Cornell

Kavli Affiliate: Jin Suntivich | First 5 Authors: Oleg Yu. Gorobtsov, Yumeng Song, Kevin Fritz, Daniel Weinstock, Yifei Sun | Summary: Nanostructured proton-conducting ceramics (PCCs) have attracted considerable interest as moderate-temperature proton conductors. Structure dynamics during proton conduction, particularly at grain boundaries, are crucial for stability and proton transport in nanostructured PCCs. A common assumption […]
