Criticality around the Spinodal Point of First-Order Quantum Phase Transitions
Fan Zhang, Chiao Wang, H. T. Quan
Universality and scaling are hallmarks of second-order phase transitions but are generally unexpected in first-order quantum phase transitions (FOQPTs). We present a microscopic th…

Phase diagrams of S=1/2 bilayer Models of SU(2) symmetric antiferromagnets
Fan Zhang, Nisheeta Desai, Wenan Guo +1
We study the phase diagrams of models of bilayers of square lattices antiferromagnets with SU(2) Heisenberg symmetry that have 2, 4, and 6 spin exchanges. We study tw…
