The Sloan Digital Sky Survey Reverberation Mapping Project: UV-Optical Accretion Disk Measurements with Hubble Space Telescope

Posted by klaurent Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Y. Homayouni, Megan R. Sturm, Jonathan R. Trump, Keith Horne, C. J. Grier | Summary: We present accretion-disk structure measurements from UV-optical reverberation mapping observations of a sample of eight quasars at 0.24<z<0.85. Ultraviolet photometry comes from two cycles of Hubble Space Telescope monitoring, accompanied by […]

Ladder Symmetries of Black Holes: Implications for Love Numbers and No-Hair Theorems

Posted by klaurent Chicago

Kavli Affiliate: Austin Joyce | First 5 Authors: Lam Hui, Austin Joyce, Riccardo Penco, Luca Santoni, Adam R. Solomon | Summary: It is well known that asymptotically flat black holes in general relativity have a vanishing static, conservative tidal response. We show that this is a result of linearly realized symmetries governing static (spin 0,1,2) […]

Continuous measurement of a qudit using dispersively coupled radiation

Posted by klaurent Berkeley

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: John Steinmetz, Debmalya Das, Irfan Siddiqi, Andrew N. Jordan, | Summary: We analyze the continuous monitoring of a qudit coupled to a cavity using both phase-preserving and phase-sensitive amplification. The quantum trajectories of the system are described by a stochastic master equation, for which we derive the […]

Heritable differences in synaptic zinc-transporter levels drive variation in learned birdsong

Posted by klaurent UCSF

Kavli Affiliate: Michael Brainard | Authors: DG. Mets, W. H. Mehaffey, B. M. Colquitt and M. S. Brainard | Summary: Abstract The authors have withdrawn this manuscript. During revision of our manuscript, we carried out several lines of additional experiments and analyses that failed to fully support and reproduce the results previously presented in Figure […]

Strange pentaquarks and excited $Ξ$ hyperons in $Ξ_b^- to J/ψ ΛK^-$ final states

Posted by klaurent Chicago

Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: We comment on the recent evidence by the LHCb Collaboration for a structure in the $J/psi Lambda$ final state produced in the decay $Xi^-_b to J/psi Lambda K^-$, with minimal quark content $c bar c u d […]

Generation of Switchable Singular Beams with Dynamic Metasurfaces

Posted by klaurent Peking

Kavli Affiliate: Li Xin Li | First 5 Authors: Ping Yu, Jianxiong Li, Xin Li, Gisela Schuetz, Michael Hirscher | Summary: Singular beams have attracted great attention due to their optical properties and broad applications from light manipulation to optical communications. However, there has been a lack of practical schemes with which to achieve switchable […]

Chern-Simons Invariants from Ensemble Averages

Posted by klaurent Tokyo

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Meer Ashwinkumar, Matthew Dodelson, Abhiram Kidambi, Jacob M. Leedom, Masahito Yamazaki | Summary: We discuss ensemble averages of two-dimensional conformal field theories associated with an arbitrary indefinite lattice with integral quadratic form $Q$. We provide evidence that the holographic dual after the ensemble average is the three-dimensional […]
