From: Particle-hole symmetry and the reentrant integer quantum Hall Wigner solid
The Wigner solid we report on is the reentrant integer quantum Hall Wigner solid (RIQHWS), seen between the filling factors ν = 2 − 1/5 and 2 − 2/9. The high-field Wigner solid (HFWS) and integer quantum Hall Wigner solid (IQHWS) are related by particle–hole symmetry. Similarly, the reentrant Wigner solid (RWS) and the reentrant integer quantum Hall Wigner solid (RIQHWS) are also related by particle–hole symmetry.
