Edge quantum criticality and emergent supersymmetry in topological phases
Zi-Xiang Li, Yi-Fan Jiang, Hong Yao
Proposed as a fundamental symmetry describing our universe, spacetime supersymmetry (SUSY) has not been discovered yet in nature. Nonetheless, it has been predicted that SUSY may e…
Fractional charge and emergent mass hierarchy in diagonal two-leg t-J cylinders
Yi-Fan Jiang, Hong-Chen Jiang, Hong Yao +1
We define a new class of "diagonal" t-J ladders rotated by /4 relative to the canonical lattice directions of the square lattice, and study it using density matrix renormalizati…
Charge-4e superconductors: a Majorana quantum Monte Carlo study
Yi-Fan Jiang, Zi-Xiang Li, Steven A. Kivelson +1
Many features of charge-4e superconductors remain unknown because even the "mean-field Hamiltonian" describing them is an interacting model. Here we introduce an interacting model…
Majorana-time-reversal symmetries: a fundamental principle for sign-problem-free quantum Monte Carlo simulations
Zi-Xiang Li, Yi-Fan Jiang, Hong Yao
A fundamental open issue in physics is whether and how the fermion sign problem in quantum Monte Carlo (QMC) simulations can be solved generically. Here, we show that Majorana-time…
