Acceleration and Velocity Dissociate Temporal Phases of Postural Control in Rhesus Macaques

Posted by dbos Hopkins

Kavli Affiliate: Kathleen Cullen | Authors: Olivia M. E. Leavitt Brown, Bassil A Ramadan and Kathleen E Cullen | Summary: Maintaining balance requires the nervous system to transform sensory signals about unexpected postural perturbations into precisely timed motor commands. Although human studies have established that postural responses unfold in distinct temporal phases, how specific kinematic […]

Tracking the local order parameter through the Hubbard exciton decoherence time in the Mott-Hubbard insulator LaVO3

Posted by klaurent Cornell

Kavli Affiliate: Darrell Schlom | Summary:The prototypical Mott-Hubbard insulator LaVO3 undergoes a structural phase transition accompanied by the onset of spin and orbital ordering below 140 K. By combining ultrafast optical pump-probe spectroscopy and two-dimensional electronic spectroscopy, we investigate the interplay between fluctuations of the local spin and orbital order parameter and the lifetime of […]

An Optically Addressable Transmissive Liquid Crystal Metasurface Spatial Light Modulator

Posted by klaurent Caltech

Kavli Affiliate: Harry Atwater | Summary:Active wavefront control in high-power laser illumination systems is important for technologies such as additive manufacturing, free-space laser communication, and power transmission. Conventional spatial light modulators (SLMs) and mechanical beam-steering devices are unsuitable for such applications as they rely on metal mirrors and electrical contacts which are damaged under high […]
