Query: Supersolid phase and magnetization plateaus observed in anisotropic
  spin-3/2 Heisenberg model on bipartite lattices   We study the spin-3/2 Heisenberg model including easy-plane and exchange
anisotropies in one and two dimensions. In the Ising limit, when the
off-diagonal exchange interaction J is zero, the phase diagram in magnetic
field is characterized by magnetization plateaus that are either
translationally invariant or have a two-sublattice order, with phase boundaries
that are macroscopically degenerate. Using a site factorized variational wave
function and perturbational expansion around the Ising limit, we find that
superfluid and supersolid phases emerge between the plateaus for small finite
values of J. The variational approach is complemented by a Density Matrix
Renormalization Group study of a one-dimensional chain and exact
diagonalization calculations on small clusters of a square lattice. The studied
model may serve as a minimal model for the layered Ba2CoGe2O7 material
compound, and we believe that the vicinity of the uniform 1/3 plateau in the
model parameter space can be observed as an anomaly in the measured
magnetization curve.
