Hybrid LQG-Neural Controller for Inverted Pendulum System
E. S. Sazonov, P. Klinkhachorn, R. L. Klein
The paper presents a hybrid system controller, incorporating a neural and an LQG controller. The neural controller has been optimized by genetic algorithms directly on the inverted…
Long-Lived Spin Coherence States
Yuriy V. Pershin
We study evolution of electron spin coherence having non-homogeneous direction of spin polarization vector in semiconductor heterostructures. It is found that the electron spin rel…
Drift-Diffusion Approach to Spin-Polarized Transport
Yuriy V. Pershin
We develop a drift-diffusion equation that describes electron spin polarization density in two-dimensional electron systems. In our approach, superpositions of spin-up and spin-dow…
Magnetization of Nuclear-Spin-Polarization-Induced Quantum Ring
S. N. Shevchenko, Yu. V. Pershin, I. D. Vagner
Properties of a Nuclear-Spin-Polarization-Induced Quantum Ring (NSPI QR) are studied theoretically. In the proposed system a local nuclear spin polarization creates an effective hy…
On the entropy of spanning trees on a large triangular lattice
M. L. Glasser, F. Y. Wu
The double integral representing the entropy S_{tri} of spanning trees on a large triangular lattice is evaluated using two different methods, one algebraic and one graphical. Both…
Decoherence Rate of Semiconductor Charge Qubit Coupled to Acoustic Phonon Reservoir
L. Fedichkin, A. Fedorov
We analyze decoherence of an electron in a double-dot due to the interaction with acoustic phonons. For large tunneling rates between the quantum dots, the main contribution to dec…
