Resolving topological order crossovers on NISQ hardware
Ruizhe Shen, Yin Zhong, Ching Hua Lee
Topological phases of matter provide a promising route toward robust quantum information processing, but on present-day noisy intermediate-scale quantum devices the experimentally…
Hubbard-assisted stability of Hatsugai-Kohmoto correlations in a one-dimensional open chain
Yan-Xiao Wang, Yin Zhong
The Hatsugai-Kohmoto (HK) model has recently been identified as a fixed-point description of Mottness that is stable against perturbing local interactions. This raises a natural qu…
Altermagnetism in exactly solvable model: the Ising-Kondo lattice model
Miaomiao Zhao, Wei-Wei Yang, Yin Zhong
Altermagnet (AM), a recently identified class of collinear magnet, has garnered significant attention due to its unique combination of zero net magnetization and spin-split energy…
Near-flat-band-driven violation of Pauli limit in heavy fermion superconductors
Yan-Xiao Wang, Yin Zhong
Heavy-fermion superconductors often display upper critical fields that exceed the conventional Pauli paramagnetic limit, indicating that strong correlations and hybridized quasipar…
Phenomenological Noise Models and Optimal Thresholds of the 3D Toric Code
Ji-Ze Xu, Yin Zhong, Miguel A. Martin-Delgado +2
Three-dimensional (3D) topological codes offer the advantage of supporting fault-tolerant implementations of non-Clifford gates, yet their performance against realistic noise remai…
Quantum Quench Dynamics in an Exactly Solvable Two-Dimensional Non-Fermi Liquid System
Hui Li, Run-Yu Chen, Wen-Yuan Liu +2
Understanding the behavior of non-Fermi liquids (NFLs) is an important topic in condensed matter physics. Here we introduce an exactly solvable multi-orbital model based on iron ox…
One-dimensional interacting Su-Schrieffer-Heeger model at quarter filling: An exact diagonalization study
Yan-Xiao Wang, Yin Zhong
This study explores the ground-state phase diagram and topological properties of the spinless 1D Su-Schrieffer-Heeger (SSH) model with nearest-neighbor (NN) interactions at quarter…
Violation of Luttinger's theorem in one-dimensional interacting fermions
Meng Gao, Yin Zhong
Using the density matrix renormalization group method, we systematically investigate the evolution of the Luttinger integral in the one-dimensional generalized - model as a f…
Robust Simulations of Many-Body Symmetry-Protected Topological Phase Transitions on a Quantum Processor
Ruizhe Shen, Tianqi Chen, Bo Yang +2
Topology and symmetry play critical roles in characterizing quantum phases of matter. Recent advancements have unveiled symmetry-protected topological (SPT) phases in many-body sys…
