Topological superconductivity in a Hubbard model for twisted bilayer cuprates
T. Vibert, D. Sénéchal, D. Sénéchal
We investigate the emergence of nontrivial topology in a twisted cuprate bilayer described by the Hubbard model in the weak-interaction regime. Our results show that the topologica…

Subbath Cluster Dynamical Mean-Field Theory
A. de Lagrave, D. Sénéchal, M. Charlebois
Cluster Dynamical Mean-Field Theory (CDMFT) with an Exact Diagonalization (ED) impurity solver faces exponential scaling limitations from the Hilbert space dimension. We introduce…

The role of the apical oxygen in cuprate high-temperature superconductors
Samuel Vadnais, Rémi Duchesne, Kristjan Haule +3
Scanning tunneling microscopy measurements exploiting the natural superstructure modulation of the cuprate superconductor BiSrCaCuO (Bi-2212) have revealed a p…
