Finite-Momentum Pairing State in Unconventional Rashba Systems

Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Song-Bo Zhang, Ning Hao, , | Summary: In systems with unconventional Rashba bands, we propose that a finite-momentum pairing state can emerge without the need for an external magnetic field. We analyze the phase transition from a zero-momentum Bardeen-Cooper-Schrieffer (BCS) state to a finite-momentum pairing […]

ATOMS: ALMA three-millimeter observations of massive star-forming regions — XVIII. On the origin and evolution of dense gas fragments in molecular shells of compact HII regions

Kavli Affiliate: Ke Wang | First 5 Authors: Siju Zhang, Tie Liu, Ke Wang, Annie Zavagno, Guido Garay | Summary: Fragmentation and evolution for the molecular shells of the compact HII regions are less explored compared to their evolved counterparts. We map nine compact HII regions with a typical diameter of 0.4 pc that are […]

LiNeS: Post-training Layer Scaling Prevents Forgetting and Enhances Model Merging

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Nikolaos Dimitriadis, Alessandro Favero, Guillermo Ortiz-Jimenez, Francois Fleuret | Summary: Large pre-trained models exhibit impressive zero-shot performance across diverse tasks, but fine-tuning often leads to catastrophic forgetting, where improvements on a target domain degrade generalization on other tasks. To address this challenge, we introduce LiNeS, […]

LiNeS: Post-training Layer Scaling Prevents Forgetting and Enhances Model Merging

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Nikolaos Dimitriadis, Alessandro Favero, Guillermo Ortiz-Jimenez, Francois Fleuret | Summary: Fine-tuning pre-trained models has become the standard approach to endow them with specialized knowledge, but it poses fundamental challenges. In particular, textit{(i)} fine-tuning often leads to catastrophic forgetting, where improvements on a target domain degrade […]

Universality in the Near-Side Energy-Energy Correlator

Kavli Affiliate: Feng Yuan | First 5 Authors: Xiaohui Liu, Werner Vogelsang, Feng Yuan, Hua Xing Zhu, | Summary: We investigate the energy-energy correlator (EEC) of hadrons produced on the same side in $e^+e^-$ annihilation or in leading jets in $pp$ collisions. We observe a remarkable universality of the correlator. Using a non-perturbative transverse momentum […]
