Flexoelectric and flexomagnetic effects can be important in ferromagnetic or antiferromagnetic thin films, nanoparticles, magnetic vortices, skyrmions, and other curved domain structures. Using a direct matrix method we establish the structure, inclu

In spite of more than 60 years of research, hundreds of publications, and dramatic influence on properties, the driving force of the formation of the polar nanoregion (PNR) in the paraelectric phase of perovskite ferroelectrics and consequent relaxor

Off-center displacement of Nb in KNbO3 is explained in terms of the pseudo Jahn–Teller effect in octahedral clusters [NbO6]. Strength of this symmetry-breaking effect is determined by electron-vibrational coupling and by the HOMO–LUMO energy gap.

Delayed luminescence involving charge-carrier trapping and detrapping has recently been identified as a widespread and possibly universal phenomenon in colloidal quantum dots. Its near-power-law decay suggests a relationship with blinking. Here, usin

Additional unpaired electrons have been introduced into colloidal ZnO quantum dots (QDs) photochemically and investigated by experimental and theoretical methods to test various possible descriptions of their wave functions. For n-type ZnO QDs with d

Reduction factors (RF's), which are needed when modeling vibronic systems by an effective Hamiltonian in an electronic basis, are calculated for the ${T}_{1u}\ensuremath{\bigotimes}{h}_{g}$ Jahn-Teller (JT) system. The results obtained will be useful

The complex problem of the multimode Jahn-Teller effect for an impurity ion at a cubic site is studied in terms of tunnelling of oscillator states localized in trigonal minima on the lowest sheet of the adiabatic potential energy surface. The low-sym

We present an analysis of the Jahn - Teller (JT) system in which both possible h-type quadratic terms are considered. It is well known that this results in pentagonal or trigonal minima on the potential energy surface, depending on the magnitudes of

In all linear Jahn-Teller (JT) systems studied to date, the ground state, after allowing for the vibronic interaction, has always been of the same symmetry as the original electronic state. Furthermore, the ground state remains the same symmetry for
