On Symmetry Groups of Some Quadratic Programming Problems
A. V. Eremeev, A. S. Yurkov
Solution and analysis of mathematical programming problems may be simplified when these problems are symmetric under appropriate linear transformations. In particular, a knowledge…
To the theoretical description of the losses in inductance coils
A. S. Yurkov
The article discusses a theory that allows to describe losses in conductors taking into account the skin effect and the proximity effect. The developed theory is applied to inducta…
Impact of surface phenomena on direct bulk flexoelectric effect in finite samples
A. S. Yurkov, A. K. Tagantsev
In the framework of a continuum theory, it is shown that the direct flexoelectric response of a finite sample essentially depends on the surface polarization energy, even in the th…
On the Continual Theory of Flexoelectric Deformations
A. S. Yurkov
In many cases the correct theoretical description of flexoelectricity requires the consideration of the finite size of a body and is reduced to the solution of boundary problems fo…
Phases and phase transitions of a perturbed Kekulé-Kitaev model
Eoin Quinn, Subhro Bhattacharjee, Roderich Moessner
We study the quantum spin liquid phase in a variant of the Kitaev model where the bonds of the honeycomb lattice are distributed in a Kekulé pattern. The system supports gapped and…
On the flexoelectric deformations of finite size bodies
A. S. Yurkov
Exact equations describing flexoelectric deformation in solids, derived previously within the framework of a continuum media theory, are partial differential equations of the fourt…
Flexoelectric deformation of a homogeneously polarized ball
A. S. Yurkov
The problem of finding the elastic strains arising due to the converse flexoelectric effect is solved for a case of uniformly polarized ball of isotropic dielectric material. The s…
On the Simple Approach to Critical Phenomena Description
A. S. Yurkov
Simple field-theoretical approach to critical phenomena is described. In contrast to the Wilson's theory, a description in real 3-dimensions space is used. At the same time the des…
Flexoelectric effect in finite samples
Alexander K. Tagantsev, Alexander S. Yurkov
Static flexoelectric effect in a finite sample of a solid is addressed in terms of phenomenological theory for the case of a thin plate subjected to bending. It has been shown that…
