Title: Construction of a series of new $$\textit{ν}$$ = 2/5 fractional quantum Hall wave functions by conformal field theory

Abstract

In this paper, a series of $$\textit{ν}$$ = 2/5 fractional quantum Hall wave functions are constructed from conformal field theory(CFT). They share the same topological properties with states constructed by Jain's composite fermion approach. Upon exact lowest Landau level (LLL) projection, some of Jain's composite fermion states would not survive if constraints on Landau level indices given in the appendices of this paper were not satisfied. By contrast, states constructed from CFT are always in LLL. These states are characterized by different topological shifts and multibody relative angular momenta. Further, as a by-product, in the appendices we prove the necessary conditions for general $$\textit{ν = p}$$/(2$$\textit{p}$$ + 1) composite fermion states to have nonvanishing LLL projection.
