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 paper studies how adding an onsite Hubbard repulsion affects the Hatsugai‑Kohmoto model in a half‑filled one‑dimensional spinful fermion chain, finding that the Hubbard term ca…
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…
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…
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…
