Reevaluating Quantum Geometric Criteria for Itinerant Magnetic Instabilities
Min-Fong Yang
The interplay between quantum geometry and electron correlation has emerged as a compelling paradigm in quantum many-body physics. Recent studies have highlighted the diagnostic ut…
Interaction-induced Metal to Topological Insulator Transition
Yu-Chin Tzeng, Po-Yao Chang, Min-Fong Yang
By means of exact diagonalizations, the Bernevig-Hughes-Zhang model at quarter-filling in the limit of strong Hubbard on-site repulsion is investigated. We find that the non-intera…
Comment on "Coulomb Instabilities of a Three-Dimensional Higher-Order Topological Insulator"
Yu-Wen Lee, Min-Fong Yang
Based on renormalization-group (RG) calculations, a recent Letter by Zhao et al [Phys. Rev. Lett. 127, 176601 (2021)] claimed that three-dimensional second-order topological insula…
Fate of Fermi-arc States in Gapped Weyl Semimetals under Long-ranged Interactions
Yu-Chin Tzeng, Min-Fong Yang
For noninteracting Weyl semimetals (WSMs), Fermi-arc surface states can arise when there exist gapless Weyl nodes in the bulk single-particle spectrum. However, in the presence of…
Manifestation of topological behaviors in interacting Weyl systems: one-body verse two-body correlations
Min-Fong Yang
Understanding correlation effects in topological phases of matter is at the forefront of current research in condensed matter physics. Here we try to clarify some subtleties in stu…
Field-Induced Quantum Phases in Frustrated Spin-Dimer Model: A Sign-Problem-Free Quantum Monte Carlo Study
Kwai-Kong Ng, Min-Fong Yang
The magnetization process of a frustrated spin-1/2 spin-dimer model on a square lattice is investigated by means of a sign-problem-free quantum Monte Carlo algorithm developed rece…
