Chern-Simons composite fermion theory of fractional Chern insulators [PDF]
, 2017 We formulate a Chern-Simons composite fermion theory for fractional Chern insulators (FCIs), whereby bare fermions are mapped into composite fermions coupled to a lattice Chern-Simons gauge theory. We apply this construction to a Chern insulator model on

Surprising robustness of particle-hole symmetry for composite-fermion liquids [PDF]
, 2017 We report on fixed phase diffusion Monte Carlo calculations that show that, even for a large amount of Landau level mixing, the energies of the Pfaffian and anti-Pfaffian phases remain very nearly the same, as also do the excitation gaps at $1/3$ and $2 ...

Strongly-interacting mirror fermions at the LHC
EPJ Web of Conferences, 2017 The introduction of mirror fermions corresponding to an interchange of leftwith right-handed fermion quantum numbers of the Standard Model can lead to a model according to which the BEH mechanism is just an effective manifestation of a more fundamental ...

Large composite fermion effective mass at filling factor 5/2
Nature Communications, 2023 The 5/2 fractional quantum Hall effect in the second Landau level of extremely clean two-dimensional electron gases has attracted much attention due to its topological order predicted to host quasiparticles that obey non-Abelian quantum statistics and ...

Baryon spectrum of SU(4) composite Higgs theory with two distinct fermion representations [PDF]
Physical Review D, 2018 We use lattice simulations to compute the baryon spectrum of SU(4) lattice gauge theory coupled to dynamical fermions in the fundamental and two-index antisymmetric (sextet) representations simultaneously.

Composite fermion duality for half-filled multicomponent Landau levels [PDF]
, 2016 We study the interplay of particle-hole symmetry and fermion-vortex duality in multicomponent half-filled Landau levels, such as quantum Hall gallium arsenide bilayers and graphene.

Electron Number Density and Coherence Length of Boson-Fermion Pair in HTSC
Advances in High Energy Physics, 2022 A Bose-Einstein Condensate (BEC) of a nonzero momentum Cooper pair constitutes a composite boson or simply a boson. Previously, it has been shown that the quantum coherence of the two-component BEC (boson and fermion condensates) is controlled by ...

Entanglement Entropy of the ν=1/2 Composite Fermion Non-Fermi Liquid State. [PDF]
Physical Review Letters, 2014 The so-called "non-Fermi liquid" behavior is very common in strongly correlated systems. However, its operational definition in terms of "what it is not" is a major obstacle for the theoretical understanding of this fascinating correlated state. Recently

Nuclear Physics B, 2023 The ultraviolet completion is the Standard Model (SM) gauge-symmetric four-fermion couplings at the high-energy cutoff. Composite particles appear in the gauge symmetric phase in contrast with SM particles in the spontaneous symmetry-breaking phase.

Composite fermion model for entanglement spectrum of fractional quantum Hall states [PDF]
, 2015 We show that the entanglement spectrum associated with a certain class of strongly correlated many-body states --- the wave functions proposed by Laughlin and Jain to describe the fractional quantum Hall effect --- can be very well described in terms of ...
