Kavli Affiliate: Jia Liu | First 5 Authors: Junzhuo Li, Bo Wang, Xiuze Zhou, Peijie Jiang, Jia Liu | Summary: The interpretability of Mixture-of-Experts (MoE) models, especially those with heterogeneous designs, remains underexplored. Existing attribution methods for dense models fail to capture dynamic routing-expert interactions in sparse MoE architectures. To address this issue, we propose […]

Kavli Affiliate: Misao Sasaki | First 5 Authors: Diego Cruces, Shi Pi, Misao Sasaki, , | Summary: $delta N$ formalism is a useful method to calculate the curvature perturbation. Contrary to what it is typically done in the literature, we re-formulate the $delta N$ formalism by using the $e$-folding number $n$ counted forward in time. […]

Kavli Affiliate: Jia Liu | First 5 Authors: Srijith Nair, Michael Lin, Peizhong Ju, Amirreza Talebi, Elizabeth Serena Bentley | Summary: Collaborative training methods like Federated Learning (FL) and Split Learning (SL) enable distributed machine learning without sharing raw data. However, FL assumes clients can train entire models, which is infeasible for large-scale models. In […]

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Yuan Miao, Linhao Li, Hosho Katsura, Masahito Yamazaki, | Summary: Quantum many-body scars (QMBS) serve as important examples of ergodicity-breaking phenomena in quantum many-body systems. Despite recent extensive studies, exact QMBS are rare in dimensions higher than one. In this paper, we study a two-dimensional quantum $mathbb{Z}_2$ […]

Kavli Affiliate: Simeon Hellerman | First 5 Authors: Jahmall Bersini, Simeon Hellerman, Domenico Orlando, Susanne Reffert, | Summary: We study the fixed point of the three-dimensional NJL model in a double-scaling limit where both the charge $Q$ and the number of fermion flavors $N$ become large with a fixed ratio $q=Q/(2N)$. While a similar analysis […]

Kavli Affiliate: Yasunori Nomura | First 5 Authors: Yasunori Nomura, Tomonori Ugajin, , , | Summary: We study how meaningful physical predictions can arise in nonperturbative quantum gravity in a closed Lorentzian universe. In such settings, recent developments suggest that the quantum gravitational Hilbert space is one-dimensional and real for each $alpha$-sector, as induced by […]

Kavli Affiliate: Jia Liu | First 5 Authors: Zhiyao Zhang, Myeung Suk Oh, FNU Hairi, Ziyue Luo, Alvaro Velasquez | Summary: Actor-critic methods for decentralized multi-agent reinforcement learning (MARL) facilitate collaborative optimal decision making without centralized coordination, thus enabling a wide range of applications in practice. To date, however, most theoretical convergence studies for existing […]

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Dan Kondo, Hitoshi Murayama, Bea Noether, , | Summary: Gauge theories can be solved exactly slightly away from the supersymmetric (SUSY) limit softly broken by anomaly mediation when the size of SUSY breaking is much smaller than the dynamical scale ($m ll Lambda$). We show empirical evidence […]
