Particle-hole symmetry and the reentrant integer quantum Hall Wigner solid

Abstract The interplay of strong Coulomb interactions and topology is currently under intense scrutiny in various condensed matter atomic systems. One example this the phase competition fractional quantum Hall states Wigner solid two-dimensional electron gas. Here we report a at ν = 1.79 its melting due to correlations occurring 9/5. This solid, that call reentrant integer develops range Landau level filling factors related by particle-hole symmetry so called solid. We thus find GaAs/AlGaAs system straddles partial factor 1/5 not only lowest factors, but also near Our results highlight as fundamental extended family solids paint complex picture with states.
