Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Raisa-Ioana Biega, Marina R. Filip, Linn Leppert, Jeffrey B. Neaton, | Summary: Halide double perovskites with alternating silver and pnictogen cations are an emerging family of photoabsorber materials with robust stability and band gaps in the visible range. However, the nature of optical excitations in these […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Oscar Macias, Harm van Leijen, Deheng Song, Shin’ichiro Ando, Shunsaku Horiuchi | Summary: The leading explanation of the $textit{Fermi}$ Galactic center $gamma$-ray excess is the extended emission from a unresolved population of millisecond pulsars (MSPs) in the Galactic bulge. Such a population would, along with the prompt […]
Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Gabriel Jung, Toshiya Namikawa, Michele Liguori, Dipak Munshi, Alan Heavens | Summary: We investigate three-point statistics in weak lensing convergence, through the integrated bispectrum. This statistic involves measuring power spectra in patches, and is thus easy to measure, and avoids the complexity of estimating the very large […]
Kavli Affiliate: David Muller | First 5 Authors: Tobias A. Kampmann, David Müller, Clemens Franz Vorsmann, Lukas Paul Weise, Jan Kierfeld | Summary: We discuss the rejection-free event-chain Monte-Carlo algorithm and several applications to dense soft matter systems. Event-chain Monte-Carlo is an alternative to standard local Markov-chain Monte-Carlo schemes, which are based on detailed balance, […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Shin Kobayashi, Yuhei Nakayama, Satoshi Shirai, | Summary: Recently, the chiral superconductivity of the cosmic string in the axion model has gathered attention. The superconductive nature can alter the standard understanding of the cosmology of the axion model. For example, a string loop with a […]
