Higher-order hopping-parameter expansion by human-AI collaboration
Masakiyo Kitazawa, Tatsuya Wada
We develop efficient algorithms for evaluating higher-order terms in the hopping-parameter expansion of on gauge configurations. The resulting…
Lee-Yang zeros and edge singularity in a mean-field approach
Tatsuya Wada, GyÅzÅ Kovács, Masakiyo Kitazawa +1
The analytic structure of the partition function in finite-volume systems is investigated at complex chemical potentials in a minimal mean-field effective model of QCD with finite-…
Lee-Yang-zero ratio method in three-dimensional Ising model
Tatsuya Wada, Masakiyo Kitazawa, Kazuyuki Kanaya
By performing Monte Carlo simulations of the three-dimensional Ising model, we apply the recently proposed Lee-Yang-zero ratio (LYZR) method to determine the location of the critic…
Locating Critical Points Using Ratios of Lee-Yang Zeros
Tatsuya Wada, Masakiyo Kitazawa, Kazuyuki Kanaya
We propose a method to numerically determine the location of a critical point in general systems using the finite-size scaling of Lee-Yang zeros. This method makes use of the fact…
Lee-Yang zeros in heavy-quark QCD
Masakiyo Kitazawa, Tatsuya Wada, Kazuyuki Kanaya
We explore the distribution of Lee-Yang zeros around the critical point that appears in the heavy-quark region of QCD at nonzero temperature in lattice numerical simulations. With…
Finite-size scaling of Lee-Yang zeros and its application to the 3-state Potts model and heavy-quark QCD
Tatsuya Wada, Masakiyo Kitazawa, Kazuyuki Kanaya
We propose a new general method to study critical points (CP) using the finite-size scaling of Lee-Yang zeros (LYZ). We first study the LYZ in the three-dimensional Ising model on…
