Multiple Magnetorotons and Spectral Sum Rules in Fractional Quantum Hall Systems
Dung Xuan Nguyen, F. D. M. Haldane, E. H. Rezayi +2
We study numerically the the charge neutral excitations (magnetorotons) in fractional quantum Hall systems, concentrating on the two Jain states near quarter filling, and $…
Energetics of the PH-Pfaffian state and the 5/2-fractional quantum Hall effect
Edward H. Rezayi, Kiryl Pakrouski, F. D. M. Haldane
We present a method for the exact construction of the fully particle-hole symmetric PH-Pfaffian ground state and its charged excitations on a sphere. We adopt the Moore-Read state,…
Graviton Chirality and Topological Order in the Half-filled Landau Level
F. D. M. Haldane, E. H. Rezayi, Kun Yang
The fractional quantum Hall state at Landau level (LL) filling factor 5/2 is extremely interesting because it is likely the first non-Abelian state, but its precise nature remains…
