Bi₄Ti₃O₁₂-PVC composites were fabricated. Ceramics powders of bismuth titanate were prepared by the sol-gel method using bismuth nitrate pentahydrate Bi(NO₃)₃⋅₅H₂O and tetrabutyl titanate Ti(CH₃(CH₂)₃O)₄ as precursors. The ...

We study the bath dynamics in the dephasing model of a two-state quantum system (qubit) coupled to an environment of harmonic oscillators. This model was shown [Morozov et al., Phys. Rev. A, 2012 85, 022101] to admit the ...

The comparative experimental analysis of polarization reversal kinetics in conventional homogeneous triglycine sulfate (NH₂ CH₂ COOH)₃ ˙ H₂SO₄; TGS) and relaxor strontium barium niobate (Sr₀.₆₁Ba₀.₃₉Nb₂O₆; SBN) crystals ...

We investigated the effect of uniaxial pressure (0÷1000 bars) applied parallely to the ac electric field on dielectric properties of PLZT-x/65/35 (2≤x≤13) ceramics. There was revealed a significant effect of the external ...

The effects of the length of each hydrophobic end block Nst and polymer concentration φP on the transition broadness in amphiphilic ABA symmetric triblock copolymer solutions are studied using the self-consistent field ...

We present the technology of obtaining and the electrophysical properties of a multicomponent material 0.61PMN-0.20PT-0.09PS-0.1PFN:Li (PMN-PT-PS-PFN:Li). The addition of PFN into PMN-PT decreases the temperature of final ...

Quantum many body physics and solid state theory in Lviv and Ukraine have always been linked with the name of Professor Ihor Stasyuk, a prominent scientist who celebrates his 75th birthday.

We present the first theoretical study of the merging of diabolical points in the context of superconducting circuits. We begin by studying an analytically solvable four-level model which may serve as theoretical pattern ...

Using the effective mass and rectangular potential approximations, the theory of electron dynamic conductivity is developed for the plane multilayer resonance tunnel structure placed into a constant electric field within ...

We consider the dynamics of pattern formation in a system of point defects under sustained irradiation within the framework of the rate theory. In our study we generalize the standard approach taking into account a production ...
