Field-induced freezing in the unfrustrated Ising antiferromagnet
Adam Iaizzi
We study instantaneous quenches from infinite temperature to well below in the two-dimensional square lattice Ising antiferromagnet in the presence of a longitudinal external…

Bose-Einstein condensation of deconfined spinons in two dimensions
Adam Iaizzi, Harley D Scammell, Oleg P Sushkov +1
The transition between the Néel antiferromagnet and the valence-bond solid state in two dimensions has become a paradigmatic example of deconfined quantum criticality, a non-Landau…

Metamagnetism and zero-scale-factor universality in the two-dimensional - model
Adam Iaizzi, Kedar Damle, Anders W. Sandvik
Using a combination of quantum Monte Carlo and exact methods, we study the field-driven saturation transition of the two-dimensional - model, in which the antiferromagnetic H…
