Uncertainty Principle and Off-Diagonal Long Range Order in the Fractional Quantum Hall Effect | | L.Pitaevskii

23 Oct 1992 | | Abstract: | A natural generalization of the Heisenberg uncertainty principle inequality holding for non hermitian operators is presented and applied to the fractional quantum Hall effect (FQHE). This inequality was used in a previous paper to prove the absence of long range order in the ground state of several 1D systems with continuous group symmetries. In this letter we use it to rule out the occurrence of Bose-Einstein condensation in the bosonic representation of the FQHE wave function proposed by Girvin and MacDonald. We show that the absence of off-diagonal long range order in this 2D problem is directly connected with the $q^2$ behavior of the static structure function $S(q)$ at small momenta. | | Source: | arXiv, cond-mat/9210023 | | Services: | Forum | Review | PDF | Favorites | |
