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…
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…
