Phase diagram and Ashkin-Teller universality in the classical square-lattice Heisenberg-compass model
Yuchen Fan
We determine the finite-temperature phase diagram and critical behavior of the classical square-lattice Heisenberg-compass model using large-scale Monte Carlo simulations and finit…

Liquid-gas analog multicriticality in a frustrated Ising bilayer
Yuchen Fan
We report the discovery of a multicritical point that extends the liquid-gas paradigm to systems with competing symmetry-breaking orders. Using large-scale Monte Carlo simulations…
