Quantum Charge-4e Superconductivity and Deconfined Pseudocriticality in the Attractive SU(4) Hubbard Model
Zhou-Quan Wan, Huan Jiang, Xuan Zou +2
Unlike conventional charge-2e superconductors, a charge-4e superconductor exhibits long-range coherence of electron quartets rather than Cooper pairs. Clear zero-temperature realiz…

Monte Carlo Methods in the Manifold of Hartree-Fock-Bogoliubov Wave Functions
Ettore Vitali, Peter Rosenberg, Shiwei Zhang
We explore the possibility to implement random walks in the manifold of Hartree-Fock-Bogoliubov wave functions. The goal is to extend state-of-the-art quantum Monte Carlo approache…
