The control of overt and covert attention across two nodes of the attention-control network

Kavli Affiliate: Winrich Freiwald | Authors: Pablo Polosecki, Sara C Steenrod, Heiko Stemmann and Winrich A. Freiwald | Summary: Attention is a central cognitive capability whose focus is thought to be directed by a spatial map coding behavioral priority. Here we tested the three defining properties of priority map theory with electrophysiological recordings from two […]

The Intrabinary Shock and Companion Star of Redback Pulsar J2215+5135

Kavli Affiliate: Roger W. Romani | First 5 Authors: Andrew G. Sullivan, Roger W. Romani, , , | Summary: PSR J2215+5135 (J2215) is a `redback’ spider pulsar, where the intrabinary shock (IBS) wraps around the pulsar rather than the stellar-mass companion. Spider orbital light curves are modulated, dominated by their binary companion thermal emission in […]

Rearrangement collision theory of phonon-driven exciton dissociation

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Christopher J. N. Coveney, Jonah B. Haber, Antonios M. Alvertis, Jeffrey B. Neaton, Marina R. Filip | Summary: Understanding the processes governing the dissociation of excitons to free charge carriers in semiconductors and insulators is of central importance for photovoltaic applications. Dyson’s $mathcal{S}$-matrix formalism provides a […]

Sensitivity and control of a 6-axis fused-silica seismometer

Kavli Affiliate: Richard Mittleman | Summary:We present a pair of seismometers capable of measurement in all six axes of rigid motion. The vacuum-compatible devices implement compact interferometric displacement sensors to surpass the sensitivity of typical electrical readout schemes. Together with the capability to subtract the sensitivity-limiting coupling of ground tilt into horizontal motion, our seismometers […]

Detection of entanglement via moments of positive maps

Kavli Affiliate: Mazhar Ali | Summary: We have reexamined the moments of positive maps and the criterion based on these moments to detect entanglement. For two qubits, we observed that reduction map is equivalent to partial transpose map as the resulting matrices have the same set of eigenvalues although both matrices look different in same […]
