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…

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…

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…

1-Form Symmetric Projected Entangled-Pair States

Yi Tan, Ji-Yao Chen, Didier Poilblanc +2

The 1-form symmetry, manifesting as loop-like symmetries, has gained prominence in the study of quantum phases, deepening our understanding of symmetry. However, the role of 1-form…
