Active Sensing as Bayes-Optimal Sequential Decision Making

Kavli Affiliate: Angela J. Yu | First 5 Authors: Sheeraz Ahmad, Angela J. Yu, , , | Summary: Sensory inference under conditions of uncertainty is a major problem in both machine learning and computational neuroscience. An important but poorly understood aspect of sensory processing is the role of active sensing. Here, we present a Bayes-optimal […]

Polytype control of spin qubits in silicon carbide

Kavli Affiliate: Viatcheslav V. Dobrovitski | First 5 Authors: Abram L. Falk, Bob B. Buckley, Greg Calusine, William F. Koehl, Viatcheslav V. Dobrovitski | Summary: Crystal defects can confine isolated electronic spins and are promising candidates for solid-state quantum information. Alongside research focusing on nitrogen vacancy centers in diamond, an alternative strategy seeks to identify […]

A Decade-Baseline Study of the Plasma States of Ejecta Knots in Cassiopeia A

Kavli Affiliate: Sarah N. T. Heine | First 5 Authors: John Rutherford, Daniel Dewey, Enectali Figueroa-Feliciano, Sarah N. T. Heine, Fabienne A. Bastien | Summary: We present the analysis of 21 bright X-ray knots in the Cassiopeia A supernova remnant from observations spanning 10 yr. We performed a comprehensive set of measurements to reveal the […]

Elliptic genera of two-dimensional N=2 gauge theories with rank-one gauge groups

Kavli Affiliate: Kentaro Hori | First 5 Authors: Francesco Benini, Richard Eager, Kentaro Hori, Yuji Tachikawa, | Summary: We compute the elliptic genera of two-dimensional N=(2,2) and N=(0,2) gauged linear sigma models via supersymmetric localization, for rank-one gauge groups. The elliptic genus is expressed as a sum over residues of a meromorphic function whose argument […]

Reading between the lines of four-dimensional gauge theories

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Starting with a choice of a gauge group in four dimensions, there is often freedom in the choice of magnetic and dyonic line operators. Different consistent choices of these operators correspond to distinct physical theories, with the same correlation functions […]
