A Short-lived Rejuvenation during the Decades-long Changing-look Transition in the Nucleus of Mrk 1018

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Kai-Xing Lu, Yan-Rong Li, Qingwen Wu, Luis C. Ho, Zhi-Xiang Zhang | Summary: Changing-look active galactic nuclei (CL-AGNs), characterized by emerging or disappearing of broad lines accompanied with extreme continuum flux variability, have drawn much attention for their potential of revealing physical processes underlying AGN evolution. […]

A Trade-Off Between Path Entanglement and Quantum Sensitivity

Posted by dbos MIT

Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Benjamin Lou, Hudson A. Loughlin, Nergis Mavalvala, , | Summary: Entanglement often increases quantum measurement schemes’ sensitivity. However, we find that in precision measurements with zero-mean Gaussian states, such as squeezed states, entanglement between different paths degrades measurement sensitivity. We prove an inverse relationship between entanglement entropy […]

The Higgs-Amplitude mode in the optical conductivity in the presence of a supercurrent: Gauge-invariant formulation with disorder

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Rufus Boyack, K. Levin, , | Summary: Observing the “Higgs" or amplitude mode in superconductors has been a central challenge in condensed matter physics. Moreover, arriving at a theoretical understanding of this mode and how it is accessible in, say, conductivity experiments presents an additional […]

The Higgs-Amplitude mode in the optical conductivity in the presence of a supercurrent: Gauge invariant forumulation

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Rufus Boyack, K. Levin, , | Summary: Observing the amplitude-Higgs mode in superconductors has been a central challenge in condensed matter physics. Unlike the phase mode in the electromagnetic (EM) response, the amplitude mode is not needed to satisfy gauge invariance. Indeed, it couples to […]

Multi-sample non-negative spatial factorization

Posted by dbos Hopkins

Kavli Affiliate: Loyal Goff | Authors: Yi Wang, Kyla Woyshner, Chaichontat Sriworarat, Genevieve Stein-O’Brien, Loyal A Goff and Kasper D Hansen | Summary: Analyzing multi-sample spatial transcriptomics data requires accounting for biological variation. We present multi-sample non-negative spatial factorization (mNSF), an alignment-free framework extending single-sample spatial factorization (NSF) to multi-sample datasets. mNSF incorporates sample-specific spatial […]

A giant planet transiting a 3-Myr protostar with a misaligned disk

Posted by dbos MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Madyson G. Barber, Andrew W. Mann, Andrew Vanderburg, Daniel Krolikowski, Adam Kraus | Summary: Astronomers have found more than a dozen planets transiting 10-40 million year old stars, but even younger transiting planets have remained elusive. A possible reason for the lack of such discoveries is that […]
