Query: Flavor Symmetry and Ferroelectric Nematics in Transition Metal
  Dichalcogenides   Recent magneto-transport experiments have provided compelling evidence for
the presence of an energetically isolated threefold Q-valley degeneracy in
few-layer transition metal dichalcogenides. We study the flavor SU(3) symmetry
breaking when each Landau level triplet is one-third filled or empty and
predict that a pure flavor nematic phase and a flavorless charge-density-wave
phase will occur respectively below and above a critical magnetic field.
Surprisingly, electrons carry flavor-dependent electric dipole moments even at
zero magnetic field, rendering the nematics ferroelectric, allowing
electric-field manipulation of the flavors, and leading to the concept of
flavortronics.
