Query: Field-induced superfluids and Bose liquids in Projected Entangled Pair
  States   In two-dimensional incompressible quantum spin liquids, a large enough
magnetic field generically induces "doping" of polarized S=1 triplons or S=1/2
spinons. We review a number of cases such as spin-3/2 AKLT or spin-1/2
Resonating Valence Bond (RVB) liquids where the Projected Entangled Pair States
(PEPS) framework provides very simple and comprehensive pictures. On the
bipartite honeycomb lattice, simple PEPS can describe Bose condensed triplons
(AKLT) or spinons (RVB) superfluids with transverse staggered (N\'eel) magnetic
order. On the Kagome lattice, doping the RVB state with deconfined spinons or
triplons (i.e. spinon bound pairs) yields uncondensed Bose liquids preserving
U(1) spin-rotation symmetry. We find that spinon (triplon) doping destroys
(preserves) the topological Z_2 symmetry of the underlying RVB state. We also
find that spinon doping induces longer range interactions in the entanglement
Hamiltonian, suggesting the emergence of (additive) log-corrections to the
entanglement entropy.
