The flexoelectricity describes the contribution of the linear couplings between the electric
polarization and strain gradient and between polarization gradient and strain to the …

Flexoelectricity—the coupling between polarization and strain gradients—is a universal
effect allowed by symmetry in all materials. Following its discovery several decades ago …

The flexoelectric effect is the response of electric polarization to a mechanical strain
gradient. It can be viewed as a higher-order effect with respect to piezoelectricity, which is …

Antiferroelectrics are essential ingredients for the widely applied piezoelectric and
ferroelectric materials: the most common ferroelectric, lead zirconate titanate is an alloy of …

What causes Cooper pairs to form in unconventional superconductors is often elusive
because experimental signatures that connect to a specific pairing mechanism are rare …

By using a symmetry motivated basis to evaluate local distortions against pair distribution
function data, we show without prior bias, that the off-center Ti displacements in the …

Ferroelectrics, with their spontaneous switchable electric polarization and strong coupling
between their electrical, mechanical, thermal, and optical responses, provide functionalities …

We demonstrate how the quantum paraelectric ground state of SrTiO 3 can be accessed via
a microscopic ab initio approach based on density functional theory. At low temperature the …

Pronounced anomalies in the SrTiO 3 dynamical structure factor, S (Q, E), including the
disappearance of acoustic phonon branches at low temperatures, were uncovered with …

Dynamical multiferroicity features entangled dynamic orders: fluctuating electric dipoles
induce magnetization. Hence, the material with paraelectric fluctuations can develop …
