Mixed-State Phase Transitions in Measurement-Dressed Imaginary-Time Evolution
Yi-Ming Ding, Zenan Liu, Xu Tian +3
Motivated by the ubiquity of decoherence in quantum hardware and the growing role of imaginary-time evolution (ITE) in quantum algorithms, we investigate how many-body correlations…
Scaling of the disorder operator at (3+1)D O(3) quantum criticality
Xuyang Liang, Xiao-Chuan Wu, Zenan Liu +3
The disorder operator, as an easily measured nonlocal observable, displays great potential in detecting intrinsic information of field theories. It has been systematically studied…
Boundary Renormalization Group Flow of Entanglement Entropy at a (2+1)-Dimensional Quantum Critical Point
Zhiyan Wang, Zhe Wang, Yi-Ming Ding +3
We investigate the second-order Rényi entanglement entropy at the quantum critical point of a spin-1/2 antiferromagnetic Heisenberg model on a columnar dimerized square lattice. Th…
Bipartite entanglement and surface criticality: The extra contribution of non-ordinary edge in entanglement
Yanzhang Zhu, Zenan Liu, Zhe Wang +2
Recent works on the scaling behaviors of entanglement entropy at the SO(5) deconfined quantum critical point (DQCP) sparked a huge controversy. Different bipartitions gave out tota…
Detecting underlying symmetry-protected topological phases via strange correlators and edge engineering
Zhe Wang, Longye Lu, Shang-Qiang Ning +4
The vast majority of symmetry-protected topological (SPT) states are difficult to detect, which often leads to their misidentification as ordinary or topologically trivial phases.…
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…
Complete finite-size scaling theory of Renyi thermal entropy for second, first and weak first order quantum phase transitions
Zhe Wang, Yanzhang Zhu, Yi-Ming Ding +2
Establishing the nature of a quantum phase transition in finite-size simulations -- whether continuous, first-order, or weak first-order -- is a fundamental challenge in quantum ma…
Worldline deconfinement and emergent long-range interaction in the entanglement Hamiltonian and in the entanglement spectrum
Zenan Liu, Zhe Wang, Dao-Xin Yao +1
The entanglement spectrum (ES) is a powerful tool for probing topological phases. While its behavior in gapped systems is well understood, its properties in gapless regimes remain…
Singularity and universality from von Neumann to Rényi entanglement entropy and disorder operator in Motzkin chains
Jianyu Wang, Zenan Liu, Zheng Yan +1
The Rényi entanglement entropy is widely used in studying quantum entanglement properties in strongly correlated systems, whose analytic continuation as the Rényi index i…
