Flat-band physics in the spin-1/2 sawtooth chain
Oleg Derzhko, Jürgen Schnack, D. V. Dmitriev +2
We consider the strongly anisotropic spin-1/2 model on the sawtooth-chain lattice with ferromagnetic longitudinal interaction and aniferromagnetic transversal int…
The model of stress distribution in polymer electrolyte membrane
Vadim V. Atrazhev, Tatiana Yu. Astakhova, Dmitry V. Dmitriev +4
An analytical model of mechanical stress in a polymer electrolyte membrane (PEM) of a hydrogen/air fuel cell with porous Water Transfer Plates (WTP) is developed in this work. The…
The Dynamics of Platinum Precipitation in an Ion Exchange Membrane
S. F. Burlatsky, M. Gummalla, V. V. Atrazhev +3
Microscopy of polymer electrolyte membranes that have undergone operation under fuel cell conditions, have revealed a well defined band of platinum in the membrane. Here, we propos…
Surface tension model for surfactant solutions at the critical micelle concentration
S. F. Burlatsky, V. V. Atrazhev, D. V. Dmitriev +5
A model for the limiting surface tension of surfactant solutions (surface tension at and above the critical micelle concentration, cmc) was developed. This model takes advantage of…
Stalled phase transition model of high-elastic polymer
V. V. Atrazhev, S. F. Burlatsky, D. V. Dmitriev +1
The microscopic model of semi-crystalline polymer in high-elastic state is proposed. The model is based on the assumption that, below the melting temperature, the semi-crystalline…
Quantum oscillations of dissipative resistance in crossed electric and magnetic fields
Scott Dietrich, Sean Byrnes, Sergey Vitkalov +2
Oscillations of dissipative resistance of two-dimensional electrons in GaAs quantum wells are observed in response to an electric current I and a strong magnetic field applied perp…
Quantum lifetime of 2D electron in magnetic field
Scott Dietrich, S. A. Vitkalov, D. V. Dmitriev +1
The lifetime of two dimensional electrons in GaAs quantum wells, placed in weak quantizing magnetic fields, is measured using a simple transport method in broad range of temperatur…
Influence of the heterointerface sharpness on exciton recombination dynamics in an ensemble of (In,Al)As/AlAs quantum dots with indirect band-gap
T. S. Shamirzaev, J. Debus, D. S. Abramkin +7
The dynamics of exciton recombination in an ensemble of indirect band-gap (In,Al)As/AlAs quantum dots with type-I band alignment is studied. The lifetime of confined excitons which…
