    Abstract: In order to protect coherence of quantum states and reduce the impact of environment on quantum information, we investigate decoherence and relaxation time of magnetopolaron in the presence of three dimensional impurity under strong parabolic potential. The first states energies have been evaluated using the Lee Low Pine transformation and Pekar-ty... Show More

    Abstract: Composite nanocoatings on the surface of a titanium electrode are obtained by electrochemical reduction of macroions and fibroin nanoparticles in the presence of tricalcium phosphate. Based on the measurements, the dependence of the reduced viscosity (hуд/C) on C was constructed according to the Huggins formula hуд/C = [h] + k[h]2C (where k is a co... Show More
