Kavli Affiliate: Yasunori Nomura | First 5 Authors: Yasunori Nomura, , , , | Summary: A quantum system with a black hole accommodates two widely different, though physically equivalent, descriptions. In one description, based on global spacetime of general relativity, the existence of the interior region is manifest, while understanding unitarity requires nonperturbative quantum gravity […]
Kavli Affiliate: Amnon Yariv | First 5 Authors: Avraham Gover, Bin Zhang, Du Ran, Reuven Ianconescu, Aharon Friedman | Summary: Free-Electron Bound-Electron Resonant Interaction (FEBERI) is the resonant inelastic interaction of periodically density-bunched free electrons with a quantum two level system. We present a comprehensive relativistic quantum mechanical theory for this interaction in a model […]

Kavli Affiliate: Lee McCuller | First 5 Authors: Dhruva Ganapathy, Lee McCuller, Jameson Graef Rollins, Evan D. Hall, Lisa Barsotti | Summary: Gravitational waves produced at kilohertz frequencies in the aftermath of a neutron star collision can shed light on the behavior of matter at extreme temperatures and densities that are inaccessible to laboratory experiments. […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Hyunsung D. Jun, Roberto J. Assef, Christopher M. Carroll, Ryan C. Hickox, Yonghwi Kim | Summary: The absence of high Eddington ratio, obscured Active Galactic Nuclei (AGN) in local ($zlesssim0.1$) samples of moderate luminosity AGN has generally been explained to result from radiation pressure on the dusty […]
Kavli Affiliate: Andrei Faraon | First 5 Authors: Conner Ballew, Gregory Roberts, Philip Camayd-Muñoz, Maximilien F Debbas, Andrei Faraon | Summary: Metasurfaces advanced the field of optics by reducing the thickness of optical components and merging multiple functionalities into a single layer device. However, this generally comes with a reduction in performance, especially for multifunctional […]
Kavli Affiliate: Christopher J. Burke | First 5 Authors: Steve Bryson, Michelle Kunimoto, Ravi K. Kopparapu, Jeffrey L. Coughlin, William J. Borucki | Summary: We present occurrence rates for rocky planets in the habitable zones (HZ) of main-sequence dwarf stars based on the Kepler DR25 planet candidate catalog and Gaia-based stellar properties. We provide the […]
Kavli Affiliate: Anthony Challinor | First 5 Authors: Thibaut Louis, Sigurd Naess, Xavier Garrido, Anthony Challinor, | Summary: We present a simple approximation that can speed up the computation of the mode-coupling matrices, which are usually the bottleneck for computing unbiased angular power spectra, as well as their associated covariance matrices, of the cosmic microwave […]
Kavli Affiliate: Anthony Challinor | First 5 Authors: Antón Baleato Lizancos, Anthony Challinor, Julien Carron, , | Summary: Efforts to detect a primordial $B$-mode of CMB polarization generated by inflationary gravitational waves ought to mitigate the large variance associated with the $B$-modes produced by gravitational lensing, a process known as delensing. A popular approach to […]
