Kavli Affiliate: Misao Sasaki | First 5 Authors: Misao Sasaki, Vicharit Yingcharoenrat, Ying-li Zhang, , | Summary: Recently, it was shown that in the absence of gravity there exist non-$O(4)$-symmetric instanton solutions with finite action beyond Coleman’s instantons. In this paper, focusing on the false-vacuum decay in a single scalar field in flat Euclidean space, […]
Kavli Affiliate: Huajia Wang | First 5 Authors: Jie Gu, Yunfeng Jiang, Huajia Wang, , | Summary: We elaborate on the resurgence analysis on the $Toverline{T}$-deformed 2d conformal field theory (CFT). Writing the deformed partition function as an infinite series in the deformation parameter $lambda$, we develop efficient analytical methods to compute high-order terms of […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yong Yang, Geraint F. Lewis, Denis Erkal, Ting S. Li, Andrew P. Li | Summary: The Ophiuchus stellar stream presents a puzzle due to its complicated morphology, with a substructure perpendicular to the main track (spur), a broadened tail (fanning), and a shorter than expected angular […]
Kavli Affiliate: Ruobing Dong | First 5 Authors: Pinghui Huang, Fangyuan Yu, Eve J. Lee, Ruobing Dong, Xue-Ning Bai | Summary: From the survival of dust disks for a few Myr to the establishment of chemical dichotomy, dust traps are expected to play a pivotal role in sculpting protoplanetary disks and the early planet formation […]
Kavli Affiliate: Erin Kara | First 5 Authors: Joheen Chakraborty, Erin Kara, Riccardo Arcodia, Johannes Buchner, Margherita Giustini | Summary: Quasi-periodic eruptions (QPEs) are recurring soft X-ray transients emerging from the vicinity of supermassive black holes (SMBHs) in nearby, low-mass galaxy nuclei; about ten QPE hosts have been identified thus far. Here we report the […]

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: David I. Dunsky, Gordan Krnjaic, Elena Pinetti, , | Summary: Since dark matter is only known to have gravitational interactions, it may plausibly decay to gravitons on cosmological timescales. Although such a scenario can be easily realized, there are currently no known limits on this possibility based […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Jin-Tao Jin, Yi Zhou, , , | Summary: We develop a comprehensive Ginzburg-Landau theory describing triple-Q magnetic orders on hexagonal lattices, focusing on $O(N)$ models with $N=2$ and $N=3$. Through systematic analysis of symmetry-allowed terms in the free energy, we establish complete phase diagrams governed by competing […]
