Nonlinear ac transport and local fields in quantum wires

Anisotropic property in interacting quantum wires embedded in (110) plane

“…( 3) shows that the charge conductivity of a perfect quantum wire with the RSOI and DSOI depend on the parameters g and δv. In the absence of the SOIs, i.e., α = β = 0, the dc charge conductivity σ ρ = 2K ρ e 2 /h which is in agreement with the previous studies 20 . The dc conductivity depends sensitively on the crystallographic direction θ of the waveguide structure, i.e., the anisotropic transport behavior [see the solid red line, dashed green line, and black dot-dashed in Fig.…”

Photon-assisted transport in semiconductor nanostructures

“…Contrary to the dc-transport case, where several theoretical works exist [318], the investigations of transport in 1D systems in the presence of ac fields are scarce. Furthermore, most of the theoretical work on ac-transport in Luttinger liquids focuses on the single barrier case [319,320,321,322]. The photoconductance of a 1D quantum dot embedded in a non-fermi liquid has been studied by Vicari et al [323] by means of the bosonization technique.…”

Charge transport through open driven two-level systems with dissipation

“…In low-dimensional systems, investigations have concentrated on one-dimensional models 64,65,66,67,68 , the modification of Kondo-resonances by AC fields 69,70 , mean-field type approximations 71 , or exact studies of driven few-electron systems 72,73 .…”

“…In general, AC driven systems 41,42 and their application to various mesoscopic transport 43,44,45,46,47,48,49,50 and tunneling 51,52,53,54,55,56,57,58,59,60,61,62,63 regimes have quite a long history, although the inclusion of interactions and correlations is a relatively new area. In low-dimensional systems, investigations have concentrated on one-dimensional models 64,65,66,67,68 , the modification of Kondo-resonances by AC fields 69,70 , mean-field type approximations 71 , or exact studies of driven few-electron systems 72,73 .…”
