摘要: We propose a general mechanism for renormalization of the tunneling exponents in edge states fractional quantum Hall effect. Mutual effects coupling with out-of-equilibrium 1/f noise and dissipation are considered both Laughlin sequence composite co- counter-propagating Abelian or non-Abelian statistics. For modes we demonstrate robustness proposed so called disorder-dominated phase. Prototypes these states, such as \nu=2/3 \nu=5/2, discussed detail rich phenomenology induced by presence noisy environment is presented. The justifies strong renormalizations reported many experimental observations carried out at low temperatures. show how environmental could affect relevance excitations, leading to important implications particular \nu=5/2 case.
