Chiral Edge Excitations of Fractional Chern Insulators in the Bosonic Hofstadter Model
Xiao-Han Yang, Ji-Yao Chen, Xiao-Yu Dong
The paper numerically studies the charge‑one edge excitations of a ν=1/2 bosonic fractional Chern insulator in the Hofstadter model, showing that the edge spectral function on a fi…
Tangent Space Excitation Ansatz for Quantum Circuits
Ji-Yao Chen, Bochen Huang, D. L. Zhou +3
Computing excitation spectra of quantum many-body systems is a promising avenue to demonstrate the practical utility of current noisy quantum devices, especially as we move toward…
Measurement-enhanced entanglement in a monitored superconducting chain
Rui-Jing Guo, Ji-Yao Chen, Zhi-Yuan Wei
A common view in monitored quantum dynamics is that local measurements suppress entanglement growth. We show that this intuition can fail in a one-dimensional spinful fermionic cha…
Variational preparation and characterization of chiral spin liquids in quantum circuits
Zi-Yang Zhang, Donghoon Kim, Ji-Yao Chen
Quantum circuits have been shown to be a fertile ground for realizing long-range entangled phases of matter. While various quantum double models with non-chiral topological order h…
Probing the Dynamical Structure Factor of Quantum Spin Chains via Low-Temperature Gibbs States with Matrix Product State Subspace Expansion
Tomoya Takahashi, Wei-Lin Tu, Ji-Yao Chen +1
Studying finite-temperature properties with tensor networks is notoriously difficult, especially at low temperatures, due to the rapid growth of entanglement and the complexity of…
Simulating Bulk Gap in Chiral Projected Entangled-Pair States
Ji-Yao Chen, Yi Tan, Sylvain Capponi +3
Projected entangled-pair states (PEPS) have proven effective in capturing chiral spin liquid ground states, yet the presence of long-range ``gossamer'' correlation tails raises con…
