The understanding of the structural origin of relaxor ferroelectrics has been doubtlessly a
long-standing puzzle in the field of ferroelectricity. Thus, motivated by the interest in …

A model of a thin film elastically attached to a rigid substrate is considered. In the case in
which the film expands relative to the substrate and assuming certain nonlinear elastic …

There is considerable evidence from new generations of high resolution microscopies and
scattering techniques for intrinsically multiscale structures and dynamics in complex …

We have derived the interaction between Jahn–Teller centers due to optical and acoustic
phonons. Without Coulomb repulsion the model leads to a global phase separation at low …

There is substantial evidence that the ground state in many of oxides is inhomogeneous [1].
In cuprates, for example neutron-scattering experiments suggest that phase segregation …

The properties of a system of charged particles on a 2D lattice, subject to an anisotropic
Jahn–Teller-type interaction and 3D Coulomb repulsion are investigated. Without Coulomb …

There is considerable evidence from new generations of high resolution microscopies and
scattering techniques for intrinsically multiscale structures and dynamics in complex …

Intrinsic heterogeneity, from nano-to meso-scales, of lattice/charge/spin variables, is
common in complex oxides such as cuprates and manganites, that have strain-based …
