Probing interaction induced quantum Hall states
Progress in graphene sample quality starts to disclose rich physics related to Coulomb interactions as well as interaction induced lifting of symmetries associated with the spin and pseudospin degrees of freedom. A key requirement to observe these fragile states in transport has so far been the fabrication of better quality samples. This has been accomplished by placing graphene on BN, or by su...
متن کاملDynamical critical behavior in the integer quantum Hall effect
We investigate dynamical scaling properties in the integer quantum Hall effect for non-interacting electrons at zero temperature, by means of the frequency-induced peak broadening of the dissipative longitudinal conductivity σ xx (ω). This quantity is calculated numerically in the lowest Landau level for various values of the Fermi energy E, of the frequency ω, and of the system size L. Data fo...
متن کاملEffect of external magnetic field on electron spin dephasing induced by hyperfine interaction in quantum dots
We investigate the influence of an external magnetic field on spin phase relaxation of single electrons in semiconductor quantum dots induced by the hyperfine interaction. The basic decay mechanism is attributed to the dispersion of local effective nuclear fields over the ensemble of quantum dots. The characteristics of electron spin dephasing is analyzed by taking an average over the nuclear s...
