Haerter-Shastry kinetic magnetism and metallicity in the triangular Hubbard model
The study investigates how kinetic frustration drives magnetic ordering and metallicity in a triangular Hubbard model. It found that as hole density increases, the system transitions from a 120° antiferromagnetic state to an intermediate phase characterized by multimer stripes, eventually becoming paramagnetic. This reveals kinetic frustration is key to understanding doped correlated electron systems.
