Spacetime symmetries and geometric diffusion

Kavli Affiliate: J. S. Villasenor | First 5 Authors: Marc Basquens, Antonio Lasanta, Emanuel Mompó, Valle Varo, Eduardo J. S. Villaseñor | Summary: We examine relativistic diffusion through the frame and observer bundles associated with a Lorentzian manifold $(M,g)$. Our focus is on spacetimes with a non-trivial isometry group, and we detail the conditions required […]

Iterated Monodromy Group With Non-Martingale Fixed-Point Process

Kavli Affiliate: Zheng Zhu | First 5 Authors: Jianfei He, Zheng Zhu, , , | Summary: We construct families of rational functions $f: mathbb{P}^1_k rightarrow mathbb{P}^1_k$ of degree $d geq 2$ over a perfect field $k$ with non-martingale fixed-point processes. Then for any normal variety $X$ over $mathbb{P}_{bar{k}}^N$, we give conditions on $f: X rightarrow […]

Evolution and distribution of superbubbles in simulated Milky Way-like galaxies

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Chengzhe Li, Hui Li, Wei Cui, Federico Marinacci, Laura V. Sales | Summary: Stellar feedback plays a crucial role in regulating baryon cycles of a galactic ecosystem, and may manifest itself in the formation of superbubbles in the interstellar medium. In this work, we used a set […]

Mono- and oligochromatic extreme-mass ratio inspirals

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, Yiren Lin, Kostas Tzanavaris, , | Summary: The gravitational capture of a stellar-mass object by a supermassive black hole represents a unique probe of warped spacetime. The small object, typically a stellar-mass black hole, describes a very large number of cycles before crossing […]

Neural Downscaling for Complex Systems: from Large-scale to Small-scale by Neural Operator

Kavli Affiliate: Jing Wang | First 5 Authors: Pengyu Lai, Jing Wang, Rui Wang, Dewu Yang, Haoqi Fei | Summary: Predicting and understanding the chaotic dynamics in complex systems is essential in various applications. However, conventional approaches, whether full-scale simulations or small-scale omissions, fail to offer a comprehensive solution. This instigates exploration into whether modeling […]

Antiferromagnetic Ground State, Charge Density Waves and Oxygen Vacancies Induced Metal-Insulator Transition in Pressurized La$_{3}$Ni$_{2}$O$_{7}$

Kavli Affiliate: Gang Su | First 5 Authors: Xin-Wei Yi, Ying Meng, Jia-Wen Li, Zheng-Wei Liao, Jing-Yang You | Summary: La$_{3}$Ni$_{2}$O$_{7}$ has garnered widespread interest recently due to its high-temperature superconductivity under pressure, accompanied by charge density wave (CDW) ordering and metal-insulator (MI) transitions in the phase diagram. Here, we reveal with comprehensive calculations that […]

Representing the dynamics of natural marmoset vocal behaviors in frontal cortex

Kavli Affiliate: Cory Miller | Authors: Jingwen Li, Mikio Christian Aoi and Cory Miller | Summary: Here we tested the respective contributions of primate premotor and prefrontal cortex to support vocal behavior. We applied a model-based GLM analysis that better accounts for the inherent variance in natural, continuous behaviors to characterize the activity of neurons […]
