Imaginary-time correlations in time-sliced stochastic series expansion
Ryan Flynn, Adam Iaizzi, Sibin Yang +2
Combined with numerical analytic continuation techniques, quantum Monte Carlo (QMC) methods enable the extraction of real-frequency dynamical properties from imaginary-time correla…
Variational Tensor Network Operator
Yu-Hsueh Chen, Ke Hsu, Wei-Lin Tu +2
We propose a simple and generic construction of the variational tensor network operators to study the quantum spin systems by the synergy of ideas from the imaginary-time evolution…
Excitation spectrum of spin-1 Kitaev spin liquids
Yu-Hsueh Chen, Jozef Genzor, Yong Baek Kim +1
We study the excitation spectrum of the spin-1 Kitaev model using the symmetric tensor network. By evaluating the virtual order parameters defined on the virtual Hilbert space in t…
Two-wire Junction of Inequivalent Tomonaga-Luttinger Liquids
Yao-Tai Kang, Chung-Yu Lo, Masaki Oshikawa +2
We develop two novel numerical schemes to study the conductance of the two-wire junction of inequivalent Tomonaga-Luttinger Liquids. In the first scheme we use the static current-c…
Detecting transition between Abelian and non-Abelian topological orders through symmetric tensor networks
Yu-Hsueh Chen, Ching-Yu Huang, Ying-Jer Kao
We propose a unified scheme to identify phase transitions out of the Abelian topological order, including the transition to a non-Abelian chiral spin liquid. Using l…
Entanglement Renyi negativity across a finite temperature transition: a Monte Carlo study
Kai-Hsin Wu, Tsung-Cheng Lu, Chia-Min Chung +2
Quantum entanglement is fragile to thermal fluctuations, which raises the question whether finite temperature phase transitions support long-range entanglement similar to their zer…
