Many-body effective mass enhancement in a two-dimensional electron liquid
R. Asgari, B. Davoudi, M. Polini +3
Motivated by a large number of recent magnetotransport studies we have revisited the problem of the microscopic calculation of the quasiparticle effective mass in a paramagnetic tw…
Dynamical corrections to the DFT-LDA electron conductance in nanoscale systems
Na Sai, Michael Zwolak, Giovanni Vignale +1
Using time-dependent current-density functional theory, we derive analytically the dynamical exchange-correlation correction to the DC conductance of nanoscale junctions. The corre…
Failure of the local density approximation in time-dependent spin density functional theory
Z. Qian, A. Constantinescu, G. Vignale
It has been known for some time that the exchange-correlation potential in time-dependent density functional theory is an intrinsically nonlocal functional of the density as soon a…
Effect of disorder on the non-dissipative drag
John Baker, Giovanni Vignale, A. G. Rojo
In this paper we consider the effect of disorder on the non-dissipative Coulomb drag between two mesoscopic metal rings at zero temperature. Ring 1 has an Aharonov-Bohm flux presen…
Bosonization of the two-dimensional electron gas in the lowest Landau level
S. Conti, G. Vignale
We develop a bosonization scheme for the collective dynamics of a spinless two-dimensional electron gas (2DEG) in the lowest Landau level. The system is treated as a continuous ela…
