Nonlocal Entanglement and Directional Correlations of Primordial Perturbations on the Inflationary Horizon

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, , , , | Summary: Models are developed to estimate properties of relic cosmic perturbations with "spooky" nonlocal correlations on the inflationary horizon, analogous to those previously posited for information on black hole event horizons. Scalar curvature perturbations are estimated to emerge with a dimensionless […]

Magnifications of paired micro-images emerging from a micro-lensing critical curve

Kavli Affiliate: Paul Schechter | First 5 Authors: Luke Weisenbach, Paul Schechter, Joachim Wambsganss, , | Summary: Studies of the inner regions of micro-lensed AGN during caustic crossing events have often relied upon the approximation that the magnification near a fold caustic is inversely proportional to the square root of the source-caustic distance. We examine […]

Global Simulations of Protoplanetary Disk Outflows with Coupled Non-ideal Magnetohydrodynamics and Consistent Thermochemistry

Kavli Affiliate: Lile Wang | First 5 Authors: Lile Wang, Xue-Ning Bai, Jeremy Goodman, , | Summary: Magnetized winds may be important in dispersing protoplanetary disks and influencing planet formation. We carry out global full magnetohydrodynamic simulations in axisymmetry, coupled with ray-tracing radiative transfer, consistent thermochemistry, and non-ideal MHD diffusivities. Magnetized models lacking EUV photons […]

Transport signatures of surface states in a Weyl semimetal: evidence of field driven Fermi arc interferometry

Kavli Affiliate: Jeffrey Neaton | First 5 Authors: Nityan L. Nair, Marie-Eve Boulanger, Francis Laliberté, Sinead Griffin, Sanyum Channa | Summary: A signature property of Weyl semimetals is the existence of topologically protected surface states – arcs in momentum space that connect Weyl points in the bulk. However, the presence of bulks states makes detection […]

Andreev reflection at the interface with an oxide in the quantum Hall regime

Kavli Affiliate: Joseph Falson | First 5 Authors: Yusuke Kozuka, Atsushi Sakaguchi, Joseph Falson, Atsushi Tsukazaki, Masashi Kawasaki | Summary: Quantum Hall/superconductor junctions have been an attractive topic as the two macroscopically quantum states join at the interface. Despite longstanding efforts, however, experimental understanding of this system has not been settled yet. One of the […]

Robust Model Predictive Control of Irrigation Systems with Active Uncertainty Learning and Data Analytics

Kavli Affiliate: Abraham Duncan Stroock | First 5 Authors: Chao Shang, Wei-Han Chen, Abraham Duncan Stroock, Fengqi You, | Summary: We develop a novel data-driven robust model predictive control (DDRMPC) approach for automatic control of irrigation systems. The fundamental idea is to integrate both mechanistic models, which describe dynamics in soil moisture variations, and data-driven […]

Cathodoluminescence-based nanoscopic thermometry in a lanthanide-doped phosphor

Kavli Affiliate: Naomi Ginsberg | First 5 Authors: Clarice D. Aiello, Andrea D. Pickel, Edward Barnard, Rebecca B. Wai, Christian Monachon | Summary: Crucial to analyze phenomena as varied as plasmonic hot spots and the spread of cancer in living tissue, nanoscale thermometry is challenging: probes are usually larger than the sample under study, and […]
