An explicit evolution from Néel to striped antiferromagnetic states in the spin-1/2 - Heisenberg model on the square lattice
Yun-Tong Yang, Fu-Zhou Chen, Chen Cheng +1
The frustrated spin- Heisenberg model on the square lattice has been extensively studied since 1988 because of its close relationship to the high-temperature superco…
Investigating Berezinskii-Kosterlitz-Thouless phase transitions in Kagome spin ice by quantifying Monte Carlo process: Distribution of Hamming distances
Wen-Yu Su, Feng Hu, Chen Cheng +1
We reinvestigate the phase transitions of the Ising model on the Kagome lattice with antiferromagnetic nearest-neighbor and ferromagnetic next-nearest-neighbor interactions, which…
Many-body Localization in Clean Chains with Long-Range Interactions
Chen Cheng
The strong long-range interaction leads to localization in the closed quantum system without disorders. Employing the exact diagonalization method, the author numerically investiga…
Machine learning for phase ordering dynamics of charge density waves
Chen Cheng, Sheng Zhang, Gia-Wei Chern
We present a machine learning (ML) framework for large-scale dynamical simulations of charge density wave (CDW) states. The charge modulation in a CDW state is often accompanied by…
Disorder in interacting quasi-one-dimensional systems: flat and dispersive bands
Mi-Ji Liang, Yong-Feng Yang, Chen Cheng +1
We investigate the superconductor-insulator transition (SIT) in disordered quasi-one dimensional systems using the density-matrix renormalization group method. Focusing on the case…
Defining a universal sign to strictly probe a phase transition
Nvsen Ma, Jun-Song Sun, Gaopei Pan +2
The mystery of the infamous sign problem in quantum Monte Carlo simulations mightily restricts applications of the method in fermionic and frustrated systems. A recent work [Scienc…
