Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, Domenico Orlando, Masataka Watanabe, , | Summary: We show that the standard notion of entanglement is not defined for gravitationally anomalous two-dimensional theories because they do not admit a local tensor factorization of the Hilbert space into local Hilbert spaces. Qualitatively, the modular flow cannot […]
Kavli Affiliate: Jia Liu | First 5 Authors: Yu Mei, Jia Liu, Zhiping Chen, , | Summary: We consider a distributionally robust second-order stochastic dominance constrained optimization problem. We require the dominance constraints hold with respect to all probability distributions in a Wasserstein ball centered at the empirical distribution. We adopt the sample approximation approach […]
Kavli Affiliate: Naoki Yasuda | First 5 Authors: Takayuki Ohgami, Nozomu Tominaga, Yousuke Utsumi, Yuu Niino, Masaomi Tanaka | Summary: A gravitational wave event, S190510g, which was classified as a binary-neutron-star coalescence at the time of preliminary alert, was detected by LIGO/Virgo collaboration on May 10, 2019. At 1.7 hours after the issue of its […]
Kavli Affiliate: Alexey Bondal | First 5 Authors: Agnieszka Bodzenta, Alexey Bondal, , , | Summary: We define admissible and weakly admissible subcategories in exact categories and prove that the former induce semi-orthogonal decompositions on the derived categories. We develop the theory of thin exact categories, an exact-category analogue of triangulated categories generated by exceptional […]

Kavli Affiliate: David Spergel | First 5 Authors: Sigurd Naess, Nick Battaglia, J. Richard Bond, Erminia Calabrese, Steve K. Choi | Summary: We report on the serendipitous discovery of three transient mm-wave sources using data from the Atacama Cosmology Telescope. The first, detected at RA = 273.8138, dec = -49.4628 at ${sim}50sigma$ total, brightened from […]
Kavli Affiliate: Jia Liu | First 5 Authors: Xiaoyu Cao, Minghong Fang, Jia Liu, Neil Zhenqiang Gong, | Summary: Byzantine-robust federated learning aims to enable a service provider to learn an accurate global model when a bounded number of clients are malicious. The key idea of existing Byzantine-robust federated learning methods is that the service […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yasunori Lee, Yuji Tachikawa, , , | Summary: Global gauge anomalies in $6d$ associated with non-trivial homotopy groups $pi_6(G)$ for $G=SU(2)$, $SU(3)$, and $G_2$ were computed and utilized in the past. In the modern bordism point of view of anomalies, however, they come from the bordism groups […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Guillem Domènech, Chunshan Lin, Misao Sasaki, , | Summary: We calculate the gravitational waves (GWs) induced by the density fluctuations due to inhomogeneous distribution of primordial black holes (PBHs) in the case where PBHs eventually dominate and reheat the universe by Hawking evaporation. The initial PBH density […]
