Lee-Yang Theory Guided Force Field Refinement Based on Phase Diagrams
Bin Jin, Qijun Ye, Xinzheng Li +2
We propose a general framework for automatic force field refinement guided by phase diagrams, grounded in Lee-Yang phase transition theory. The central idea is to directly use the…
Field-selective criticality in 2D melting revealed by multi-field Lee-Yang zeros
Ling Liu, Fang-Cheng Wang, Qi-Jun Ye +1
How a two-dimensional solid melts remains unsettled after 60 years of study, as theory, model systems, simulations, and atomic-resolution experiments continue to suggest conflictin…
Tracking metastable phases by complex Lee-Yang zeros
Yi-Hua Dong, Ling Liu, Fang-Cheng Wang +2
Metastable phases (MPs) are energetically unfavorable states typically suppressed in equilibrium phase diagrams. Rather than remaining ''hidden'', we show that they exist in the co…
Fermion sign problem and the structure of Lee-Yang zeros. II. Finite temperature results for a model system without interactions
Ran-Chen He, Jia-Xi Zeng, Shu Yang +3
Beyond the analysis of the Lee-Yang (LY) zero of at K presented by our previous work [He et. al. Phys. Rev. E 113, 24115 (2026)], it is important but intricate to understa…
Unconventional superconductivity from lattice quantum disorder
Yu-Cheng Zhu, Jia-Xi Zeng, Xin-Zheng Li
Unconventional superconductivity presents a defining and enduring challenge in condensed matter physics. Prevailing theoretical frameworks have predominantly emphasized electronic…
Revisiting the Fermion Sign Problem from the Structure of Lee-Yang Zeros. I. The Form of Partition Function for Indistinguishable Particles and Its Zeros at 0~K
Ran-Chen He, Jia-Xi Zeng, Shu Yang +3
To simulate indistinguishable particles, recent studies of path-integral molecular dynamics formulated their partition function as a recurrence relation involving a variable $Î…
