Chiral Edge Excitations of Fractional Chern Insulators in the Bosonic Hofstadter Model
Xiao-Han Yang, Ji-Yao Chen, Xiao-Yu Dong
Edge excitations are the defining signature of chiral topologically ordered systems. In continuum fractional quantum Hall (FQH) states, these excitations are described by the chira…

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…

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…
