Extended crossover from Fermi liquid to quasi-antiferromagnet in the half-filled 2D Hubbard model
Fedor Šimkovic, J. P. F. LeBlanc, Aaram J. Kim +4
The ground state of the Hubbard model with nearest-neighbor hopping on the square lattice at half filling is known to be that of an antiferromagnetic (AFM) band insulator for any o…
Geometric properties of the Fortuin-Kasteleyn representation of the Ising model
Pengcheng Hou, Sheng Fang, Junfeng Wang +2
We present a Monte Carlo study of the Fortuin-Kasteleyn (FK) clusters of the Ising model on the square (2D) and simple-cubic (3D) lattices. The wrapping probability, a dimensionles…
Random-length Random Walks and Finite-size scaling in high dimensions
Zongzheng Zhou, Jens Grimm, Sheng Fang +2
We address a long-standing debate regarding the finite-size scaling of the Ising model in high dimensions, by introducing a random-length random walk model, which we then study rig…
Observation of non-scalar and logarithmic correlations in 2D and 3D percolation
Xiaojun Tan, Romain Couvreur, Youjin Deng +1
Percolation, a paradigmatic geometric system in various branches of physical sciences, is known to possess logarithmic factors in its correlators. Starting from its definition, as…
Equivalent-neighbor percolation models in two dimensions: crossover between mean-field and short-range behavior
Yunqing Ouyang, Youjin Deng, Henk W. J. Blöte
We investigate the influence of the range of interactions in the two-dimensional bond percolation model, by means of Monte Carlo simulations. We locate the phase transitions for se…
The halon: a quasiparticle featuring critical charge fractionalization
Kun Chen, Yuan Huang, Youjin Deng +1
The halon is a special critical state of an impurity in a quantum-critical environment. The hallmark of the halon physics is that a well-defined integer charge gets fractionalized…
