Pair-Distribution Functions of Laughlin Quasielectrons in Partially Filled Composite Fermion Levels

Abstract: Pair-distribution functions g(r) of the Laughlin quasielectrons are calculated in the fractional quantum Hall states at electron filling factors ν = 4/11 and 3/8. They all have a shoulder at a medium range, supporting the idea of quasielectron cluster formation. The intra-and inter-cluster contributions to g(r) are identified. The average cluster sizes are estimated; pairs and triplets of quasielectrons are suggested at ν = 4/11 and 3/8, respectively.

“…However, one interesting feature can be observed for all enigmatic filling factors-a shoulder, which is especially pronounced for systems composed of less than 50 particles. This plateaulike peculiarity has already been noticed in diagonalization studies for ν = 4 11 and systems comprising up to 14 particles [52]. However, simulations were performed in a correlated CF basis and only quasi-particles from a partially filled quasi-particle level were taken into account; and all quasiparticles from completely filled quasi-particle levels were disregarded.…”

“…An investigation of various correlation functions is generally time‐consuming (especially for systems comprising tens of particles). Therefore, only a pair distribution function, g2false(boldrfalse), is commonly studied in the papers . Furthermore, signs of the solid‐like local order are already visible in this two‐body function.…”
