Effects of coupling between octahedral tilting and polar modes on the phase diagram of PbZr1-xTixO3 (PZT)
F. Cordero, F. Trequattrini, F. Craciun +1
The results are presented of anelastic and dielectric spectroscopy measurements on large grain ceramic PZT with compositions near the two morphotropic phase boundaries (MPBs) that…

Singular response to a dopant of an evaporating crystal surface
Vladislav Popkov, Paolo Politi
Moving crystal surfaces can undergo step-bunching instabilities, when subject to an electric current. We show analytically that an infinitesimal quantity of a dopant may invert the…

Hopping-resolved electron-phonon coupling in bilayer graphene
E. Cappelluti, G. Profeta
In this paper we investigate the electron-phonon coupling in bilayer graphene, as a paradigmatic case for multilayer graphenes where interlayer hoppings are relevant. Using a froze…
