Since then, an increasing amount of effort and time has been spent in investigating the physical behavior of flexoelectric materials, both theoretically and experimentally. Tagantsev [3] was
WebHidden symmetry of flexoelectric coupling Eugene A. Eliseev, Anna N. Morozovska Considering the importance of flexoelectric coupling for the physical understanding of the gradient-driven couplings in mesoscale and nanoscale solids, one has to determine its full symmetry and numerical values. WebOur goal in the following section is to determine the matrix representations of the complete flexoelectricity law, for each symmetry class. 4. Matrix Representations. It is common practice in continuum mechanics [ 34] to rewrite a constitutive tensorial law in matrix form for being able to implement it in a FEM code.

In Section 5 we study the conformal bridge transformation for the NCLP and two-vortex systems. To do this, we consider the integral of motion, which is a certain linear combination of generators of angular and temporal translations in NCLP. This integral, and its analog
WebWe discuss how the hidden symmetry can significantly simplify the problem of the flexoelectric constants determination from inelastic neutron and Raman scattering experiments due to the minimization of f ijkl independent components, opening the way for its unambiguous determination from the scattering experiments.
