Terahertz Bloch oscillator with a modulated bias
Timo Hyart, Natalia V. Alexeeva, Jussi Mattas +1
Electrons performing Bloch oscillations in an energy band of a dc-biased superlattice in the presence of weak dissipation can potentially generate THz fields at room temperature. T…
Ferromagnetism and Lattice Distortions in the Perovskite YTiO
W. Knafo, C. Meingast, H. v. Löhneysen +7
The thermodynamic properties of the ferromagnetic perovskite YTiO are investigated by thermal expansion, magnetostriction, specific heat, and magnetization measurements. The lo…
Dynamical density functional theory for molecular and colloidal fluids: a microscopic approach to fluid mechanics
A. J. Archer
In recent years, a number of dynamical density functional theories (DDFTs) have been developed for describing the dynamics of the one-body density of both colloidal and atomic flui…
Mountain trail formation and the active walker model
S. J. Gilks, J. P. Hague
We extend the active walker model to address the formation of paths on gradients, which have been observed to have a zigzag form. Our extension includes a new rule which prohibits…
Nondegenerate parametric amplification in superlattice and the limits of strong and weak dissipation
Timo Hyart, Kirill N. Alekseev
We develop a semiclassical theory of the nondegenerate parametric amplification in a single miniband of superlattice. We present the formulas describing absorption and gain of sign…
Theoretical backgrounds of nonlinear THz spectroscopy of semiconductor superlattices
Alexey V. Shorokhov, Kirill N. Alekseev
We consider terahertz absorption and gain in a single miniband of semiconductor superlattice subject to a bichromatic electric field in the most general case of commensurate freque…
