Local fields in non–linear quantum transport
In order to describe frequency-dependent quantum transport properties, it is necessary to take into account local fields. However, since the microscopic charge and current distributions are rapidly varying functions of space and time the solution of Maxwell’s equations is a complex task. Especially in the presence of non–linear effects, a selfconsistent theory of frequency and time dependent tr...
متن کاملNon-linear Transport in Quantum-Hall Smectics
Recent transport experiments have established that two-dimensional electron systems with high-index partial Landau level filling, ν∗ = ν − [ν], have ground states with broken orientational symmetry. In a mean-field theory, the broken symmetry state consists of electron stripes with local filling factor [ν] + 1, separated by hole stripes with filling factor [ν]. We have recently developed a theo...
متن کاملLocal Elds in Non{linear Quantum Transport
We investigate the dynamical interplay between currents and electromagnetic elds in frequency-dependent transport through a single-channel quantum wire with an impurity potential in the presence of electron-electron interactions. We introduce and discuss a formalism which allows a self-consistent treatment of currents and electromagnetic elds.
متن کاملNon - zero temperature transport near quantum critical points
We describe the nature of charge transport at non-zero temperatures (T ) above the two-dimensional (d) superfluid-insulator quantum critical point. We argue that the transport is characterized by inelastic collisions among thermally excited carriers at a rate of order kBT/h̄. This implies that the transport at frequencies ω kBT/h̄ is in the hydrodynamic, collision-dominated (or ‘incoherent’) regi...
متن کاملNon-zero temperature transport near fractional quantum Hall critical points
In an earlier work, Damle and the author (Phys. Rev. B in press; condmat/9705206) demonstrated the central role played by incoherent, inelastic processes in transport near two-dimensional quantum critical points. This paper extends these results to the case of a quantum transition in an anyon gas between a fractional quantized Hall state and an insulator, induced by varying the strength of an e...
