Corner entanglement scaling with projected entangled pair states
Chloé Van Bastelaere, Rui-Zhen Huang, Laurens Vanderstraeten
Entanglement scaling provides a powerful probe of universal properties at quantum critical points. In two dimensions, contributions originating from a corner-shaped bipartition exh…
Emergent conformal boundaries from finite-entanglement scaling in matrix product states
Rui-Zhen Huang, Long Zhang, Andreas M. Läuchli +3
The use of finite entanglement scaling with matrix product states (MPS) has become a crucial tool for studying 1+1d critical lattice theories, especially those with emergent confor…
Demonstrating the wormhole mechanism of the entanglement spectrum via a perturbed boundary
Zenan Liu, Rui-Zhen Huang, Zheng Yan +1
The Li-Haldane conjecture is one of the most famous conjectures in physics and opens a new research area in the quantum entanglement and topological phase. Although a lot of theore…
Conformal Boundary Conditions of Symmetry-Enriched Quantum Critical Spin Chains
Xue-Jia Yu, Rui-Zhen Huang, Hong-Hao Song +3
Some quantum critical states cannot be smoothly deformed into each other without either crossing some multicritical points or explicitly breaking certain symmetries even if they be…
Observation of Emergent Gauge Invariance in a Superconducting Circuit
Zhan Wang, Zi-Yong Ge, Zhongcheng Xiang +8
Lattice gauge theories (LGTs) are one of the most fundamental subjects in many-body physics, and has recently attracted considerable research interests in quantum simulations. Here…
Bulk and edge dynamics of a 2D Affleck-Kennedy-Lieb-Tasaki model
Zenan Liu, Jun Li, Rui-Zhen Huang +2
We study the dynamical properties of both bulk and edge spins of a two-dimensional Affleck-Kennedy-Lieb-Tasaki (AKLT) model mainly by using the stochastic series expansion quantum…
Fast scrambling dynamics and many-body localization transition in an all-to-all disordered quantum spin model
Shang-Shu Li, Rui-Zhen Huang, Heng Fan
We study the quantum thermalization and information scrambling dynamics of an experimentally realizable quantum spin model with homogeneous XX-type all-to-all interactions and rand…
Entanglement Entropy of Non-Hermitian Free Fermions
Yi-Bin Guo, Yi-Cong Yu, Rui-Zhen Huang +4
We study the entanglement properties of non-Hermitian free fermionic models with translation symmetry using the correlation matrix technique. Our results show that the entanglement…
Quantum Simulation of Lattice Gauge Theories on Superconducting Circuits: Quantum Phase Transition and Quench Dynamics
Zi-Yong Ge, Rui-Zhen Huang, Zi Yang Meng +1
Recently, quantum simulation of low-dimensional lattice gauge theories (LGTs) has attracted many interests, which may improve our understanding of strongly correlated quantum many-…
Kibble-Zurek mechanism in a one-dimensional incarnation of deconfined quantum critical point
Rui-Zhen Huang, Shuai Yin
The conventional Kibble-Zurek mechanism (KZM) describes the driven critical dynamics in the Landau-Ginzburg-Wilson (LGW) spontaneous symmetry-breaking phase transitions. However, w…
Emergent Symmetry and Conserved Current at a One Dimensional Incarnation of Deconfined Quantum Critical Point
Rui-Zhen Huang, Da-Chuan Lu, Yi-Zhuang You +2
The deconfined quantum critical point (DQCP) was originally proposed as a continuous transition between two spontaneous symmetry breaking phases in 2D spin-1/2 systems. While great…
Nonequilibrium critical dynamics in the quantum chiral clock model
Rui-Zhen Huang, Shuai Yin
In this paper we study the driven critical dynamics in the three-state quantum chiral clock model. This is motivated by a recent experiment, which verified the Kibble-Zurek mechani…
Statistical inference and feasibility determination: a nonasymptotic approach
Ying Zhu
We develop non-asymptotically justified methods for hypothesis testing about the dimensional coefficients in (possibly nonlinear) regression models. Given a function $h…
Analytic continuation with Padé decomposition
Xing-Jie Han, Hai-Jun Liao, Hai-Dong Xie +3
The ill-posed analytic continuation problem for Green's functions or self-energies can be done using the Padé rational polynomial approximation. However, to extract accurate result…
