Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yukinobu Toda, , , , | Summary: We show the existence of semiorthogonal decompositions of Donaldson-Thomas categories for $(-1)$-shifted cotangent derived stacks associated with $Theta$-stratifications on them. Our main result gives an analogue of window theorem for categorical DT theory, which has applications to d-critical analogue of […]
Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yukinobu Toda, , , , | Summary: We prove two kinds of $mathbb{Z}/2$-periodic Koszul duality equivalences for triangulated categories of matrix factorizations associated with $(-1)$-shifted cotangents over quasi-smooth affine derived schemes. We use this result to define $mathbb{Z}/2$-periodic version of Donaldson-Thomas categories for local surfaces, whose $mathbb{C}^{ast}$-equivariant […]
Kavli Affiliate: Yasunori Nomura | First 5 Authors: Kevin Langhoff, Chitraang Murdia, Yasunori Nomura, , | Summary: We study the redundancies in the global spacetime description of the eternally inflating multiverse using the quantum extremal surface prescription. We argue that a sufficiently large spatial region in a bubble universe has an entanglement island surrounding it. […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Neil D. Barrie, Chengcheng Han, Hitoshi Murayama, , | Summary: We find that the triplet Higgs of the Type II seesaw mechanism can simultaneously generate the neutrino masses and observed baryon asymmetry, while playing a role in inflation. We survey the allowed parameter space and determine that […]
Kavli Affiliate: Mikhail Kapranov | First 5 Authors: Tobias Dyckerhoff, Mikhail Kapranov, Vadim Schechtman, Yan Soibelman, | Summary: We develop the theory of semi-orthogonal decompositions and spherical functors in the framework of stable $infty$-categories. Building on this, we study the relative Waldhausen S-construction $S_bullet(F)$ of a spherical functor $F$ and equip it with a natural […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Dmitry Galakhov, Wei Li, Masahito Yamazaki, , | Summary: We introduce a class of new algebras, the shifted quiver Yangians, as the BPS algebras for type IIA string theory on general toric Calabi-Yau three-folds. We construct representations of the shifted quiver Yangian from general subcrystals of the […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Sam Young, Eiichiro Komatsu, Klaus Dolag, , | Summary: The thermal Sunyaev-Zeldovich effect contains information about the thermal history of the universe, observable in maps of the Compton $y$ parameter; however, it does not contain information about the redshift of the sources. Recent papers have utilized a […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Yutaka Tsuzuki, Shin Watanabe, Shimpei Oishi, Nobuyuki Nakamura, Naoki Numadate | Summary: The methods to measure the polarization of the x-rays from highly charged heavy ions with a significantly higher accuracy than the existing technology is needed to explore relativistic and quantum electrodynamics (QED) effects including the […]
Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Franz Herzog, Tom Melia, Jasper Roosmale Nepveu, | Summary: We renormalize massless scalar effective field theories (EFTs) to higher loop orders and higher orders in the EFT expansion. To facilitate EFT calculations with the R* renormalization method, we construct suitable operator bases using Hilbert series […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Yi-Fu Cai, Jie Jiang, Misao Sasaki, Valeri Vardanyan, Zihan Zhou | Summary: We propose a novel mechanism for enhancing the primordial gravitational waves without significantly affecting the curvature perturbations produced during inflation. This is achieved due to non-linear sourcing of resonantly amplified scalar field fluctuations. Our result […]
