Multiparty Entanglement Microscopy of Quantum Ising models in 1d, 2d and 3d
Liuke Lyu, Menghan Song, Ting-Tung Wang +2
Entanglement microscopy reveals the true quantum correlations among the microscopic building blocks of many-body systems [Nat. Commun. 16, 96 (2025)]. Using this approach, we study…
Spin excitations arising from anisotropic Dirac spinons in YCu(OD)Br[Br(OD)]
Lankun Han, Zhenyuan Zeng, Min Long +10
A Dirac quantum spin liquid hosts Dirac spinons, which are low-energy fractionalized neutral quasiparticles with spin 1/2 that obey the Dirac equation. Recent inelastic neutron sca…
Monte Carlo Simulation of Operator Dynamics and Entanglement in Dual-Unitary Circuits
Menghan Song, Zhaoyi Zeng, Ting-Tung Wang +3
We investigate operator dynamics and entanglement growth in dual-unitary circuits, a class of locally scrambled quantum systems that enables efficient simulation beyond the exponen…
An analog of topological entanglement entropy for mixed states
Ting-Tung Wang, Menghan Song, Zi Yang Meng +1
We propose the convex-roof extension of quantum conditional mutual information ("co(QCMI)") as a diagnostic of topological order in a mixed state. We focus primarily on topological…
Extracting Universal Corner Entanglement Entropy during the Quantum Monte Carlo Simulation
Yuan Da Liao, Menghan Song, Jiarui Zhao +1
The subleading corner logarithmic corrections in entanglement entropy (EE) are crucial for revealing universal characteristics of the quantum critical points (QCPs), but they are c…
Entanglement Microscopy: Tomography and Entanglement Measures via Quantum Monte Carlo
Ting-Tung Wang, Menghan Song, Liuke Lyu +2
We employ a protocol, dubbed entanglement microscopy, to reveal the multipartite entanglement encoded in the full reduced density matrix of microscopic subregion both in spin and f…
