Description:
Author(s): Adam Iaizzi, Kedar Damle, and Anders W. Sandvik We study the magnetization process of a one-dimensional extended Heisenberg model, the J − Q model, as a function of an external magnetic field h . In this model, J represents the traditional antiferromagnetic Heisenberg exchange and Q is the strength of a competing four-spin interaction. Without exter… [Phys. Rev.
