Absolute Negative Conductivity and Spontaneous Current Generation in Semiconductor Superlattices with Hot Electrons
Ethan H. Cannon, Feodor V. Kusmartsev, Kirill N. Alekseev +1
We study electron transport through a semiconductor superlattice subject to an electric field parallel to and a magnetic field perpendicular to the growth axis. Using a single mini…

New perturbation theory of low-dimensional quantum liquids II: operator description of Virasoro algebras in integrable systems
J. M. P. Carmelo, A. H. Castro Neto, D. K. Campbell
We show that the recently developed {\it pseudoparticle operator algebra} which generates the low-energy Hamiltonian eigenstates of multicomponent integrable systems also provides…

New perturbation theory of low-dimensional quantum liquids I: the pseudoparticle operator basis
J. M. P. Carmelo, A. H. Castro Neto, D. K. Campbell
We introduce a new operator algebra for the description of the low-energy physics of one-dimensional, integrable, multicomponent quantum liquids. Considering the particular case of…
