Phonon excitations of composite-fermion landau levels.
Phonon excitations of fractional quantum Hall states at filling factors nu = 1/3, 2/5, 4/7, 3/5, 4/3, and 5/3 are experimentally shown to be based on Landau-level transitions of composite fermions. At filling factor nu = 2/3, however, a linear field dependence of the excitation energy in the high-field regime rather hints towards a spin transition excited by the phonons. We propose to explain t...
متن کاملWhether composite fermion states with “wrong” chiralities dissolve into cuts
In the possible scaling region for lattice chiral fermions advocated in Nucl. Phys. B486 (1997) 282, no hard spontaneous symmetry breaking occurs and doublers are gauge-invariantly decoupled via mixing with composite three-fermion-states. However the strong coupling expansion breaks down due to no “static limit” for the low-energy limit (p ∼ 0). We further analyze relevant Green functions of th...
متن کاملOrthogonality catastrophe in a composite fermion liquid
We discuss the emergence of an orthogonality catastrophe in the response of a composite fermion liquid as the filling factor ν approaches 1/2m, where m = 1, 2, 3.... A tunneling experiment is proposed in which dramatic changes in the I-V characteristic should be observable as ν is varied. Explicit I-V characteristics calculated within the so-called Modified Random Phase Approximation, are provi...
متن کاملJustification for the Composite Fermion Picture
The mean field (MF) composite Fermion (CF) picture successfully predicts the low-lying bands of states of fractional quantum Hall systems. This success cannot be attributed to the originally proposed cancellation between Coulomb and Chern– Simons interactions beyond the mean field and solely depends on the short range of the repulsive Coulomb pseudopotential in the lowest Landau level (LL). The...
متن کاملComposite fermion theory of excitations in the fractional quantum Hall effect
Transport experiments are sensitive to charged ‘quasiparticle’ excitations of the fractional quantum Hall effect. Inelastic Raman scattering experiments have probed an amazing variety of other excitations: excitons, rotons, bi-rotons, trions, flavor altering excitons, spin waves, spin-flip excitons, and spin-flip rotons. This paper reviews the status of our theoretical understanding of these ex...
