Competing effects of Si and Mg doping on native point defects in yttrium aluminum garnet
L. Yu. Kravchenko, M. Yu. Vovsianiker, M. Y. Vovsianiker +1
We investigate how Si and Mg doping affect native point defects in yttrium aluminum garnet (YAG) by combining first-principles calculations with a thermodynamic model of defect equ…
Supersolid induced by dislocations with superfluid cores (Review article)
D. V. Fil, S. I. Shevchenko
Dislocation model of the supersolid state of He was proposed in 1987 by one of the authors of the review. The model obtained strong support by numerous experimental and theoret…
Study of magnetoelastic interaction in MnF by the acoustoelectric transformation method
I. V. Bilych, K. R. Zhekov, T. N. Haidamak +3
The mechanisms of magnetoelastic interaction in MnF are studied using the method of acoustoelectric transformation. The temperature dependence of the piezomagnetic coupling coe…
Stationary waves in a superfluid gas of electron-hole pairs in bilayers
D. V. Fil, S. I. Shevchenko
Stationary waves in the condensate of electron-hole pairs in the bilayer system are studied. The system demonstrates the transition from a uniform (superfluid) to a nonunifor…
Control of charge state of dopants in insulating crystals: Case study of Ti-doped sapphire
L. Yu. Kravchenko, D. V. Fil
We study mechanisms of control of charge state and concentration of different point defects in doped insulating crystals. The approach is based on the density functional theory cal…
Transition to a supersolid phase in a two-dimensional dilute gas of electron-hole pairs
D. V. Fil, S. I. Shevchenko
Using coherent-state formalism (the Keldysh formalism), the article describes a transition from a homogeneous superfluid state to a supersolid state in a two-dimensional dilute gas…
