We study instantaneous quenches from infinite temperature to well below ${T}_{c}$ in the two-dimensional square lattice Ising antiferromagnet in the presence of a longitudinal external magnetic field. Under single-spin-flip Metropolis algorithm Monte

The transition between the N\'{e}el antiferromagnet and the valence-bond solid state in two dimensions has become a paradigmatic example of deconfined quantum criticality, a non-Landau transition characterized by fractionalized excitations (spinons).

Using a combination of quantum Monte Carlo and exact methods, we study the field-driven saturation transition of the two-dimensional $J$-$Q$ model, in which the antiferromagnetic Heisenberg exchange $(J)$ coupling competes with an additional four-spi

We study the magnetization process of a 1D extended Heisenberg model, the J-Q model, as a function of an external magnetic field. In this model, J represents the traditional antiferromagnetic Heisenberg exchange and Q is the strength of a competing f

Deconfined quantum criticality is a type of quantum critical behavior characterized by the presence of exotic fractionalized excitations. The transition between the Neel antiferromagnet and the valence-bond solid in the J-Q model is believed to be an
