Kavli Affiliate: Tom Melia | First 5 Authors: Anne-Katherine Burns, David E. Kaplan, Tom Melia, Surjeet Rajendran, | Summary: The quantum description of time evolution in non-linear gravitational systems such as cosmological space-times is not well understood. We show, in the simplified setting of mini-superspace, that time evolution of this system can be obtained using […]

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Fabian Zimmer, Oscar Macias, Shin’ichiro Ando, Roland M. Crocker, Shunsaku Horiuchi | Summary: Since the discovery of an excess in gamma rays in the direction of M31, its cause has been unclear. Published interpretations focus on a dark matter or stellar related origin. Studies of a similar […]
Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Wenjie Xuan, Yuhang Gan, Juhua Liu, Bo Du | Summary: Existing deep learning-based change detection methods try to elaborately design complicated neural networks with powerful feature representations, but ignore the universal domain shift induced by time-varying land cover changes, including luminance fluctuations and season changes […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, , , , | Summary: In the hope of providing some intellectual entertainment on April Fools’ day of this dark year, we point out that some questions in quantum field theory are undecidable in a precise mathematical sense. More concretely, it will be demonstrated that […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, , , , | Summary: We point out that some questions in quantum field theory are undecidable in a precise mathematical sense. More concretely, it will be demonstrated that there is no algorithm answering whether a given 2d supersymmetric Lagrangian theory breaks supersymmetry or not. […]
Kavli Affiliate: Jia Liu | First 5 Authors: Vanessa Böhm, Jia Liu, , , | Summary: We study the impact of the COVID-19 pandemic on astronomy using public records of astronomical publications. We show that COVID-19 has had both positive and negative impacts on research in astronomy. We find that the overall output of the […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Masahito Yamazaki, , , , | Summary: The goal of this short article is to summarize some of the recent developments in the quiver Yangians and crystal meltings. This article is based on a lecture delivered by the author at International Congress on Mathematical Physics (ICMP), Geneva, […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Sebastian Baum, Francesco Capozzi, Shunsaku Horiuchi, , | Summary: Measuring core-collapse supernova neutrinos, both from individual supernovae within the Milky Way and from past core collapses throughout the Universe (the diffuse supernova neutrino background, or DSNB), is one of the main goals of current and next generation […]
Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Xiao-Ping Wang, Ke-Pan Xie, , | Summary: The weakly interacting massive particles (WIMPs) have been the most popular particle dark matter (DM) candidate for the last several decades, and it is well known that WIMP can be probed via the direct, indirect and collider experiments.
