Wigner Function Description of the A.C.-Transport Through a Two-Dimensional Quantum Point Contact
Igor E. Aronov, Gennady P. Berman, David K. Campbell +1
We have calculated the admittance of a two-dimensional quantum point contact (QPC) using a novel variant of the Wigner distribution function (WDF) formalism. In the semiclassical a…
Complete Pseudoparticle Representation and the Conductivity Spectrum of the Hubbard Chain
J. M. P. Carmelo, N. M. R. Peres, D. K. Campbell
We use a complete pseudoparticle operator representation to study the explicit form of the finite-frequency conductivity for the Hubbard chain. Our study reveals that the spectral…
Dissipative Chaos in Semiconductor Superlattices
Kirill N. Alekseev, Gennady P. Berman, David K. Campbell +2
We consider the motion of ballistic electrons in a miniband of a semiconductor superlattice (SSL) under the influence of an external, time-periodic electric field. We use the semi-…
