Nonlinear conductance of nanowires - A signature of Luttinger liquid effects?
M. Jonson, I. V. Krive, P. Sandström +1
We analyze recent measurements of the room temperature current-voltage characteristics of gold nanowires, whose zero current conductance is quantized in units of . A faster…
Spatial Structure in Mode Population Induced by Coherent Pumping in a Ballistic Quantum Channel
Ola Tageman, L. Y. Gorelik, R. I. Shekter +1
We predict a spatially varying mode population to appear in a GaAs/AlGaAs-2DEG ballistic quantum channel pumped by a THz-field. If a resonant coupling between two modes is suddenly…
Persistent current in a one-dimensional ring of fractionally charged "exclusons''
I. V. Krive, P. Sandström, R. I. Shekhter +1
The Aharonov-Bohm effect in a one-dimensional (1D) ring containing a gas of fractionally charged excitations is considered. It is shown that the low temperature behavior of the sys…
Coulomb Blockade-Effects on Quantization of Charge and Persistent Current in a Luttinger-Liquid Ring
I. V. Krive, P. Sandström, R. I. Shekhter +1
We show that in a ring-shaped Luttinger Liquid (LL) in contact with an electron reservoir --- the chemical potential in the ring being controlled by a gate voltage --- both t…
MICROWAVE-INDUCED "SOMERSAULT EFFECT" IN FLOW OF JOSEPHSON CURRENT THROUGH A QUANTUM CONSTRICTION
L. Y. Gorelik, V. S. Shumeiko, R. I. Shekhter +2
We consider the supercurrent flow through gated mesoscopic semiconductor hetrostructures in which a two-dimensional normal constriction is confined between superconducting electrod…
Aharonov-Bohm Oscillations in a One-Dimensional Wigner Crystal-Ring
I. V. Krive, R. I. Shekhter, S. M. Girvin +1
We calculate the magnetic moment (`persistent current') in a strongly correlated electron system --- a Wigner crystal --- in a one-dimensional ballistic ring. The flux and temperat…
