Kavli Affiliate: Emil J. Martinec | First 5 Authors: Andrea Dei, Emil J. Martinec, , , | Summary: Worldsheet string theory is solvable for a variety of backgrounds involving Neveu-Schwarz fivebranes, in terms of gauged nonlinear sigma models on group manifolds. We compute the worldsheet torus partition function of these models, and propose gauging of […]
Kavli Affiliate: Jiansheng Chen | First 5 Authors: Jingyuan Zhu, Huimin Ma, Jiansheng Chen, Jian Yuan, | Summary: Large-scale text-to-image diffusion models have achieved great success in synthesizing high-quality and diverse images given target text prompts. Despite the revolutionary image generation ability, current state-of-the-art models still struggle to deal with multi-concept generation accurately in many […]
Kavli Affiliate: E. P. S. Shellard | First 5 Authors: I. Yu. Rybak, C. J. A. P. Martins, Patrick Peter, E. P. S. Shellard, | Summary: We continue our studies of the evolution and cosmological consequences of current-carrying cosmic string networks, described by a charge-velocity-dependent one scale (CVOS) model. We present a detailed calculation of […]

Kavli Affiliate: Feng Yuan | First 5 Authors: Hai Yang, Feng Yuan, Hui Li, Yosuke Mizuno, Fan Guo | Summary: The formation of jets in black hole accretion systems is a long-standing problem. It has been proposed that a jet can be formed by extracting the rotation energy of the black hole ("BZ-jet") or the […]

Kavli Affiliate: Jia Liu | First 5 Authors: Fnu Hairi, Zifan Zhang, Jia Liu, , | Summary: In actor-critic framework for fully decentralized multi-agent reinforcement learning (MARL), one of the key components is the MARL policy evaluation (PE) problem, where a set of $N$ agents work cooperatively to evaluate the value function of the global […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: We demonstrate that gravitational particle production (GPP) of a massive, Abelian, vector (Proca) field during inflation in the presence of nonminimal coupling to gravity may suffer from an instability which leads to runaway production of […]
Kavli Affiliate: Todor Milanov | First 5 Authors: Todor Milanov, , , , | Summary: We found an interesting application of the K-theoretic Heisenberg algebras of Weiqiang Wang to the foundations of permutation equivariant K-theoretic Gromov–Witten theory. We also found an explicit formula for the genus 0 correlators in the permutation equivariant Gromov–Witten theory of […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Thomas Bohn, Hanae Inami, Aditya Togi, Lee Armus, Thomas S. -Y. Lai | Summary: We present James Webb Space Telescope (JWST) Integral Field Spectrograph observations of NGC 3256, a local infrared-luminous late-stage merging system with two nuclei about 1 kpc apart, both of which have evidence of […]
