The half-filled optical Su-Schrieffer-Heeger-Hubbard model with uniaxial strain
The study investigated how uniaxial strain affects electronic phases in a two-dimensional system modeled by the half-filled Su-Schrieffer-Heeger-Hubbard model. Introducing anisotropic hopping terms tilts the competition between bond order wave (BOW) and antiferromagnetic (AFM) phases, favoring BOW order. This strain significantly alters the phase diagram and changes how these orders appear at different temperatures.
