Logarithmic Quasi-Long-Range Order and Novel Continuous Phase Transition in the Two-Dimensional Model with Interaction
Xianzhi Pan, Zhijie Fan, Youjin Deng
We investigate the phase diagram and critical properties of the two-dimensional classical XY model with interactions decaying as . At the marginal case , we show th…
Two-dimensional percolation with algebraically decaying interactions II: Critical exponents in the long-range regime
Ziyu Liu, Tianning Xiao, Zhijie Fan +1
We present a comprehensive Monte Carlo study of two-dimensional bond percolation with algebraically decaying connection probabilities , establishing the univ…
Thermal Signatures of the Slater-Mott Crossover in the Hubbard Model: From Double Occupancy to Antiferromagnetic Correlation Length
Mingzhong Lu, Yu-Feng Song, Youjin Deng +1
The interaction-driven crossover from a Slater insulator to a Mott insulator in the Néel-ordered ground state of the Hubbard model is a fundamental paradigm of strongly correlated…
Crossover Scaling of Binder Cumulant and its application in Non-reciprocal Sandpiles
Wei Zhong, Youjin Deng
In this letter, we unveil a robust, pre-asymptotic scaling regime for the Binder cumulant , a central finite-size scaling tool, demonstrating (disor…
Scaling of Long-Range Loop-Erased Random Walks
Tianning Xiao, Xianzhi Pan, Zhijie Fan +1
We study the scaling properties of long-range loop-erased random walks (LR-LERW), where the underlying random walker performs Lévy-flight-like jumps with a power-law step-length di…
Computation of thermal entropy for the doped Hubbard Model
Yu-Feng Song, Youjin Deng, Yuan-Yao He
We develop a highly efficient framework for computing the thermal entropy in the doped Fermi-Hubbard model within the grand-canonical ensemble. The framework comprises four calcula…
Quantum Monte Carlo study of the metal-insulator crossover in the square-lattice Hubbard model
Mingzhong Lu, Yu-Feng Song, Youjin Deng +1
The interaction-driven evolution from a Fermi liquid to a Mott insulator is a hallmark of strongly correlated fermion systems. In this work, we present a {\it numerically unbiased}…
On Sak's criterion for statistical models with long-range interaction
Tianning Xiao, Ziyu Liu, Zhijie Fan +1
Determining the threshold value that separates the short-range (SR) and long-range (LR) universality classes in phase transitions remains a controversial issue. While Sak's c…
Universality Diagram of Phase Transitions in Long-range Statistical Systems
Tianning Xiao, Zhijie Fan, Youjin Deng
The percolation, Ising, and O() models constitute fundamental systems in statistical and condensed matter physics. For short-range-interacting cases, the nature of their phase t…
