Criticality on Rényi defects at (2+1) O(3) quantum critical points
Yanzhang Zhu, Zhe Wang, Meng Cheng +1
The paper uses large-scale quantum Monte Carlo simulations to study Rényi defect lines at (2+1)d O(3) quantum critical points, revealing multiple defect universality classes (ordin…
Finite-time Scaling of the surface special transition in a 3D classical Heisenberg model
Dong-Xu Liu, Dongxu Liu, Zhe Wang +2
The paper studies how the surface order parameter evolves under rapid changes of temperature or surface coupling in a 3D classical Heisenberg model, revealing that starting from an…
Spontaneous continuous-symmetry breaking and tower of states in a comb chain
Jingya Wang, Zenan Liu, Bin-Bin Mao +4
Based on the study of a one-dimensional (1D) antiferromagnetic Heisenberg model on a comb lattice, this work identifies an example of spontaneous continuous symmetry breaking in a…
Lee-Yang Zeros and Pseudocritical Drift in J-Q Néel-VBS Transitions
Chunhao Guo, Zhe Wang, Danhe Wang +3
Square-lattice J-Q models provide a sign-problem-free setting for probing the quantum phase transition between Néel antiferromagnet and columnar valence-bond solid. We analyze thi…
Entanglement Rényi Negativity across the Finite-Temperature Transition in the O(3) Universality Class
Dong-Xu Liu, Yi-Ming Ding, Zhe Wang +1
The fate of quantum entanglement at finite-temperature phase transitions remains an open question, particularly for continuous symmetry breaking where zero-temperature Goldstone mo…
Generalized Reduced-Density-Matrix Quantum Monte Carlo Gives Access to More
Zhiyan Wang, Zhe Wang, Bin-Bin Mao +1
For a long time, people have been focusing on how to extract more information, such as off-diagonal observables, from the quantum Monte Carlo (QMC) simulation of the partition func…
