Pion Distribution Amplitudes from Functional QCD
Lei Chang, Wei-jie Fu, Chuang Huang +2
The authors compute the pion distribution amplitude from first‑principles QCD using the functional renormalisation group combined with large‑momentum effective theory, obtaining a…
Diffusion Models for Sampling Near Criticality in Lattice Field Theories
Yang-yang Tan, Gert Aarts, Diaa E. Habibi +2
We investigate generative diffusion models as denoising samplers for two- and three-dimensional lattice theory across the symmetric, near-critical, and broken phases. Valida…
Solving Functional Renormalization Group Equations with Neural Networks
Yang-yang Tan, Wei-jie Fu, Lianyi He +1
We employ deep neural networks to represent the field derivative of the scale-dependent effective potential in the functional renormalization group (fRG) framework for nonperturbat…
Real-time evolution of critical modes in the QCD phase diagram
Yang-yang Tan, Shi Yin, Yong-rui Chen +2
A QCD-assisted relaxation dynamic model for the critical mode of the critical end point (CEP) in the QCD phase diagram is developed, which allows us to investigate the critical slo…
Density functional theory of renormalization group in nuclear matter
Yong-rui Chen, Wei-jie Fu, Yang-yang Tan
The density functional renormalization group (density-fRG) is proposed to investigate the density fluctuations within the functional renormalization group approach, which allows us…
Soft modes in hot QCD matter
Jens Braun, Yong-rui Chen, Wei-jie Fu +9
The chiral crossover of QCD at finite temperature and vanishing baryon density turns into a second order phase transition if lighter than physical quark masses are considered. If t…
