Magnon-Mediated Superconductivity in the Infinite- Triangular Lattice
Hantian Zhu, Yixin Zhang, Shang-Shun Zhang +2
We demonstrate that the infinite- triangular-lattice Hubbard model supports a superconducting state built from tightly bound Cooper pairs composed of two holes and one magnon ($…

Antiferromagnetism and Tightly Bound Cooper Pairs Induced by Kinetic Frustration
Yixin Zhang, Cristian Batista, Yang Zhang
Antiferromagnetism and superconductivity are often viewed as competing orders in correlated electron systems. Here, we demonstrate that kinetic frustration in hole motion facilitat…

Insulating charge transfer ferromagnetism
Yixin Zhang, Yang Zhang
We propose a mechanism for insulating ferromagnetism in the honeycomb Hubbard model of semiconductor moiré superlattices. The ferromagnetism emerges at critical charge transfer reg…
