Categorifying non-commutative deformations

Kavli Affiliate: Alexey Bondal | First 5 Authors: Agnieszka Bodzenta, Alexey Bondal, , , | Summary: We define the functor $textrm{ncDef}_{(Z_1,ldots,Z_n)}$ of non-commutative deformations of an $n$-tuple of objects in an arbitrary $k$-linear abelian category $mathcal{Z}$. In our categorified approach, we view the underlying spaces of infinitesimal flat deformations as Deligne finite categories, i.e. finite […]

Neural Network-based Top Tagger with Two-Point Energy Correlations and Geometry of Soft Emissions

Kavli Affiliate: Mihoko M. Nojiri | First 5 Authors: Amit Chakraborty, Sung Hak Lim, Mihoko M. Nojiri, Michihisa Takeuchi, | Summary: Deep neural networks trained on jet images have been successful in classifying different kinds of jets. In this paper, we identify the crucial physics features that could reproduce the classification performance of the convolutional […]

Anomaly inflow and $p$-form gauge theories

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Chang-Tse Hsieh, Yuji Tachikawa, Kazuya Yonekura, , | Summary: Chiral and non-chiral $p$-form gauge fields have gravitational anomalies and anomalies of Green-Schwarz type. This means that they are most naturally realized as the boundary modes of bulk topological phases in one higher dimensions. We give a systematic […]

High Performance Heat Conductor with Small Spring Constant for Cryogenic Applications

Kavli Affiliate: Takaaki Kajita | First 5 Authors: Tomohiro Yamada, Takayuki Tomaru, Toshikazu Suzuki, Takafumi Ushiba, Nobuhiro Kimura | Summary: We developed a soft and high thermal conductive heat link for cryogenic applications. The measured maximum thermal conductivity was approximately 18500 W/m/K at 10 K. This spring constant was 1/43 of that of a single […]

Quiver Yangian from Crystal Melting

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Wei Li, Masahito Yamazaki, , , | Summary: We find a new infinite class of infinite-dimensional algebras acting on BPS states for non-compact toric Calabi-Yau threefolds. In Type IIA superstring compactification on a toric Calabi-Yau threefold, the D-branes wrapping holomorphic cycles represent the BPS states, and the […]

Lagrangian Neural Networks

Kavli Affiliate: David Spergel | First 5 Authors: Miles Cranmer, Sam Greydanus, Stephan Hoyer, Peter Battaglia, David Spergel | Summary: Accurate models of the world are built upon notions of its underlying symmetries. In physics, these symmetries correspond to conservation laws, such as for energy and momentum. Yet even though neural network models see increasing […]

Twist Gap and Global Symmetry in Two Dimensions

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Nathan Benjamin, Hirosi Ooguri, Shu-Heng Shao, Yifan Wang, | Summary: We show that every compact, unitary two-dimensional CFT with an abelian conserved current has vanishing twist gap for charged primary fields with respect to the $mathfrak{u}(1)times$Virasoro algebra. This means that either the chiral algebra is enhanced by […]

Gopakumar-Vafa type invariants on Calabi-Yau 4-folds via descendent insertions

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yalong Cao, Yukinobu Toda, , , | Summary: The Gopakumar-Vafa type invariants on Calabi-Yau 4-folds (which are non-trivial only for genus zero and one) are defined by Klemm-Pandharipande from Gromov-Witten theory, and their integrality is conjectured. In a previous work of Cao-Maulik-Toda, $mathrm{DT}_4$ invariants with primary insertions […]

CMB-HD: Astro2020 RFI Response

Kavli Affiliate: David Spergel | First 5 Authors: Neelima Sehgal, Simone Aiola, Yashar Akrami, Kaustuv moni Basu, Michael Boylan-Kolchin | Summary: CMB-HD is a proposed ultra-deep (0.5 uk-arcmin), high-resolution (15 arcseconds) millimeter-wave survey over half the sky that would answer many outstanding questions in both fundamental physics of the Universe and astrophysics. This survey would […]
