Dirac composite fermion theory of general Jain sequences
Physical Review Research, 2021 We reconsider the composite fermion theory of general Jain sequences with filling factor ν=N/(4N±1). We show that Goldman and Fradkin's proposal of a Dirac composite fermion leads to a violation of the Haldane bound on the coefficient of the static ...

Gauge fields as constrained composite bosons
Physics Letters B, 2021 We reconsider a scenario in which photons and other gauge fields appear as the composite vector bosons made of the fermion pairs that may happen with or without spontaneous violation of Lorentz invariance. The class of composite models for emergent gauge

Loop-generated neutrino masses in composite Higgs models
Journal of High Energy Physics, 2021 We present a composite scotogenic model for neutrino masses, which are generated via loops of ℤ2-odd composite scalars. We consider three different approaches to the couplings of the neutrinos (including three right-handed singlets) and the composite ...

Spinons as Composite Fermions [PDF]
Modern Physics Letters A, 1997 We show that gauge invariant composites in the fermionic realization of SU (N)1 conformal field theory explicitly exhibit the holomorphic factorization of the corresponding WZW primaries. In the SU (2)1 case we show that the holomorphic sector realizes the spinon Y( sl 2) algebra, thus allowing the classification of the chiral Fock space in terms of ...

Composite Laguerre pseudospectral method for Fokker-Planck equations
Mathematical Modelling and Analysis, 2023 A composite generalized Laguerre pseudospectral method for the nonlinear Fokker-Planck equations on the whole line is developed. Some composite generalized Laguerre interpolation approximation results are established.

Tripartite composite fermion states [PDF]
Physical Review B, 2013 The Read-Rezayi wave function is one of the candidates for the fractional quantum Hall effect at filling fraction $ =2+\nicefrac{3}{5}$, and thereby also its hole conjugate at $2+\nicefrac{2}{5}$. We study a general class of "tripartite" composite fermion wave functions, which reduce to the Read-Rezayi ground state and quasiholes for appropriate ...

Composite fermions with orbital magnetization [PDF]
Physical Review B, 1996 For quantum Hall systems, in the limit of large magnetic field (or equivalently small electron band mass $m_b$), the static response of electrons to a spatially varying magnetic field is largely determined by kinetic energy considerations. This response is not correctly given in existing approximations based on the Fermion Chern-Simons theory of the ...

European Physical Journal C: Particles and Fields, 2021 We introduce a unique model for a fermion-antifermion pair interacting via Dirac oscillator coupling in the presence of an external uniform magnetic field.

Paired composite-fermion wave functions [PDF]
Physical Review B, 2008 We construct a family of BCS paired composite fermion wavefunctions that generalize, but remain in the same topological phase as, the Moore-Read Pfaffian state for the half-filled Landau level. It is shown that for a wide range of experimentally relevant inter-electron interactions the groundstate can be very accurately represented in this form.
