d-Wave pair density wave superconductivity in a two-orbital model
Samuel Vadnais, Arun Paramekanti
Motivated by exploring superconductivity in multi-orbital systems, we study two orbital models of spinful fermions representing () or ( orbitals on the sq…

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…

Altermagnetism and superconductivity in a multiorbital t-J model
Anjishnu Bose, Samuel Vadnais, Arun Paramekanti
Motivated by exploring doped multi-orbital antiferromagnets (AFMs) and altermagnets (ALMs) we explore minimal - models on the square-octagon lattice which favor such collinea…
