Circuit-motivated generalized affine models characterize stimulus-dependent visual cortical shared variability

Posted by dbos December 20, 2023January 8, 2024Columbia

Kavli Affiliate: Kenneth Miller | Authors: Ji Xia, Anna Jasper, Adam Kohn and Kenneth D Miller | Summary: Correlated variability in the visual cortex is modulated by stimulus properties. The stimulus dependence of correlated variability impacts stimulus coding and is indicative of circuit structure. An affine model combining a factor proportional to mean stimulus response […]

Euclidean self-dual gravity: Ashtekar variables without gauge fixing

Posted by dbos December 20, 2023MIT

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Marc Basquens, Eduardo J. S. Villaseñor, , | Summary: The GNH method is used in this paper to study the Hamiltonian formulation of the Euclidean self-dual action. This action can be used to arrive at the complex Ashtekar formulation of General Relativity […]

Flux coupled tunable superconducting resonator

Posted by dbos December 20, 2023January 8, 2024Chicago

Kavli Affiliate: Clarence Chang | First 5 Authors: Juliang Li, Pete Barry, Tom Cecil, Marharyta Lisovenko, Volodymyr Yefremenko | Summary: We present a design and implementation of frequency-tunable superconducting resonator. The resonance frequency tunability is achieved by flux-coupling a superconducting LC-loop to a current-biased feedline; the resulting screening current leads to a change of the […]

A degenerate trion liquid in atomic double layers

Posted by dbos December 19, 2023Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Phuong X. Nguyen, Raghav Chaturvedi, Liguo Ma, Patrick Knuppel, Kenji Watanabe | Summary: Trions are a three-particle bound state of electrons and holes. Experimental realization of a trion liquid in the degenerate quantum limit would open a wide range of phenomena in quantum many-body physics. However, trions […]

A New Probe of Gravitational Parity Violation Through (Non-)Observation of the Stochastic Gravitational-Wave Background

Posted by dbos December 19, 2023January 8, 2024Chicago

Kavli Affiliate: Daniel Holz | First 5 Authors: Thomas Callister, Leah Jenks, Daniel Holz, Nicolás Yunes, | Summary: Parity violation in the gravitational sector is a prediction of many theories beyond general relativity. In the propagation of gravitational waves, parity violation manifests by inducing amplitude and/or velocity birefringence between right- and left-circularly polarized modes. We […]
