Shape descriptors of equilibrium states in a quantum lattice model with local multi-well potentials: A geometric analysis near the phase transitions in Sn${}_2$P${}_2$S${}_6$ ferroelectric crystals

S. Özüm, T. Akkurt, R. Erdem +1

We analyze the equilibrium states of quantum lattice model with local multi-well potentials for Sn${}_2$P${}_2$S${}_6$ ferroelectric crystals using the mean and Gaussian curvatures ($H$,…
