A ventral tegmental area GABAergic projection to the ventral pallidum regulates value-based decision making in mice

Posted by dbos Yale

Kavli Affiliate: Marina Picciotto | Authors: WenLiang Zhou, Hanna Yousuf, Yann S Mineur and Marina Picciotto | Summary: Activity of the mesolimbic system is essential for adaptive performance of reward-related behaviors. Within this system, dopaminergic (DAergic) neurons play a critical role in driving motivation to obtain rewards and encoding predictions and error signals during reinforcement […]

Chandra Proper Motions and Milliarcsecond Astrometry of Nineteen Pulsars

Posted by klaurent Stanford

Kavli Affiliate: Roger Romani | Summary:We present X-ray proper motion (PM) measurements of 19 pulsars using new and archival data from the Chandra X-ray Observatory, including pulsar wind trails and X-ray filaments. Precise X-ray PMs are often limited by uncertainties in aligning observations to a common reference frame. Our analysis uses unresolved X-ray flux from […]

Qubit error bursts in superconducting quantum processors of Quantum Inspire: quasiparticle pumping and anomalous time dependence

Posted by klaurent Delft

Kavli Affiliate: Leonardo Dicarlo | Summary:We investigate qubit error bursts in 5- and 7-transmon processors of similar design, fabrication and packaging, but with different types of qubit Josephson junctions. Measurements for each are performed in two refrigerators to discern device-specific from refrigerator-dependent characteristics. The duration and rate of bursts are device specific but within the […]

Observation of Room-temperature Charge Density Wave Correlations via Coherent Phonon Spectroscopy in Sn-doped Kagome Superconductor CsV$_3$Sb$_5$

Posted by klaurent UCSB

Kavli Affiliate: Leon Balents | Summary:In this work, we perform ultrafast time-resolved reflectivity measurements to track the evolution of charge density wave (CDW) correlations in Sn-doped Kagome superconductor CsV$_3$Sb$_5-x$Sn$_x$. By extracting the coherent phonon spectrum, we evidence robust signatures of CDW correlations at temperature and doping ranges far beyond the phase boundary of long-range CDW […]
