Dirac composite fermion theory of general Jain sequences [PDF]
Physical Review Research, 2021 We reconsider the composite fermion theory of general Jain's sequences with filling factor $\nu=N/(4N\pm1)$. 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 ...

Is the Composite Fermion a Dirac Particle [PDF]
Physical Review X, 2015 Quantum phenomena include the fractional quantum Hall effect, whose quasiparticle is the composite fermion. Theorists show that composite fermions possess different quantum numbers than the electrons or holes they were derived from.

Phenomenology at the LHC of composite particles from strongly interacting Standard Model fermions via four-fermion operators of NJL type [PDF]
European Physical Journal C: Particles and Fields, 2018 A new physics scenario shows that four-fermion operators of Nambu-Jona-Lasinio (NJL) type have a strong-coupling UV fixed point, where composite fermions F (bosons $$\Pi $$ Π ) form as bound states of three (two) SM elementary fermions and they couple to

Composite fermion liquid to Wigner solid transition in the lowest Landau level of zinc oxide
Nature Communications, 2018 Interactions between the constituents of a condensed matter system can drive it through a plethora of different phases due to many-body effects. A prominent platform for it is a dilute two-dimensional electron system in a magnetic field, which evolves ...

Evolution of an interacting fermion–antifermion pair in the near-horizon of the BTZ black hole
European Physical Journal C: Particles and FieldsIn this study, we investigate the evolution of a composite system comprising a fermion–antifermion pair engaged in Cornell-type non-minimal interaction in the near-horizon region of a BTZ black hole.

Hyperdeterminants and composite fermion states in fractional Chern insulators [PDF]
Physical review B, 2023 Fractional Chern insulators (FCI) were proposed theoretically about a decade ago. These exotic states of matter are fractional quantum Hall states realized when a nearly flat Chern band is partially filled, even in the absence of an external magnetic ...

Transport Properties of a Half-Filled Chern Band at the Electron and Composite Fermion Phases. [PDF]
Physical Review Letters, 2023 We consider a half-filled Chern band and its transport properties in two phases that it may form: the electronic Fermi liquid and the composite-fermion Fermi liquid. For weak disorder, we show that the Hall resistivity for the former phase is very small,

Composite Fermion Pairing Induced by Landau Level Mixing. [PDF]
Physical Review Letters, 2022 Pairing of composite fermions provides a possible mechanism for fractional quantum Hall effect at even denominator fractions and is believed to serve as a platform for realizing quasiparticles with non-Abelian braiding statistics. We present results from

Transitions from Abelian composite fermion to non-Abelian parton fractional quantum Hall states in the zeroth Landau level of bilayer graphene [PDF]
Physical review B, 2021 The electron-electron interaction in the Landau levels of bilayer graphene is markedly different from that of conventional semiconductors such as GaAs. We show that in the zeroth Landau level of bilayer graphene, in the orbital which is dominated by the ...

Microscopic derivation of Dirac composite fermion theory: Aspects of noncommutativity and pairing instabilities [PDF]
Physical review B, 2021 Building on previous work [N. Read, Phys. Rev. B 58, Z. Dong and T. Senthil, 16262 (1998); Phys. Rev. B 102, 205126 (2020)] on the system of bosons at filling factor $\nu = 1$, we derive the Dirac composite fermion theory for a half-filled Landau level ...
