Correlations of tensor field components in isotropic systems with an application to stress correlations in elastic bodies
J. P. Wittmer, A. N. Semenov, J. Baschnagel
Correlation functions of components of second-order tensor fields in isotropic systems can be reduced to an isotropic forth-order tensor field characterized by a few invariant corr…
Spatial correlation functions for non-ergodic stochastic processes of macroscopic system
J. P. Wittmer, A. N. Semenov, J. Baschnagel
Focusing on non-ergodic macroscopic systems we reconsider the variances of time averages time-series. The total variance (direct average over all time-series) is known to be the su…
Simple models for strictly non-ergodic stochastic processes of macroscopic systems
G. George, L. Klochko, A. N. Semenov +2
We investigate simple models for strictly non-ergodic stochastic processes ( being the discrete time step) focusing on the expectation value and the standard deviation…
New conserved structural fields for supercooled liquids
Jean Farago, Alexander N. Semenov, Stefan Frey +1
By considering Voronoi tessellations of the configurations of a fluid, we propose two new conserved fields, which provide structural information not fully accounted for by the usua…
Electrical anisotropy of heteroepitaxial InSb/GaAs layers
T. A. Komissarova, A. N. Semenov, D. A. Kirilenko +5
We report on study of electrical and structural properties of InSb/GaAs(001) heteroepitaxial layers in [110] and [1-10] crystallographic directions. Strong anisotropy of electron t…
Photoluminescence studies of Zeeman effect in type-II InSb/InAs nanostructures
Ya. V. Terentyev, M. S. Mukhin, A. A. Toropov +5
Electron spin polarization up to 100% has been observed in type-II narrow-gap heterostructures with ultrathin InSb insertions in an InAs matrix via investigation of circularly pola…
Spin-polarized electric currents in diluted magnetic semiconductor heterostructures induced by terahertz and microwave radiation
P. Olbrich, C. Zoth, P. Lutz +11
We report on the study of spin-polarized electric currents in diluted magnetic semiconductor (DMS) quantum wells subjected to an in-plane external magnetic field and illuminated by…
Diluted magnetic semiconductor heterostructure AlSb/InAs/ZnMnTe with giant Zeeman effect for two dimensional electrons in InAs
Ya. V. Terent'ev, C. Zoth, V. V. Bel'kov +11
A new approach to the growth of diluted magnetic semiconductors with two dimensional electron gas in InAs quantum well has been developed. The method is based on molecular-beam epi…
Microphase separation in thin block copolymer films: a weak segregation mean-field approach
Hindrik Jan Angerman, Albert Johner, Alexander N. Semenov
In this paper we consider thin films of AB block copolymer melts confined between two parallel plates. The plates are identical and may have a preference for one of the monomer typ…
