Studies of laser-heated materials on femtosecond timescales have shown that the interatomic potential can be perturbed at sufficiently high laser intensities. For gold, it has been postulated to undergo a strong stiffening leading an increase phonon energies, known as hardening. Despite efforts investigate this behavior, only measurements low absorbed energy density performed, for which interpretation experimental data remains ambiguous. By using in situ single-shot x-ray diffraction hard...
Since the first realization of reversible charge doping in graphene via field-effect devices, it has become evident how induction a gap could further enhance its potential for technological applications. Here we show that opening due to sublattice symmetry breaking also profound impact on polar response graphene. By combining ab initio calculations and analytical modelling realistic band-gap values ( eV) piezoelectric coefficient Born effective attain giant value, independent gap. In...
We show that in noncollinear magnetic molecules, nonadiabatic (dynamical) effects due to the electron-vibron coupling are time-reversal symmetry breaking interactions for vibrational field. Because electronic wave function cannot be chosen as real these a nonzero geometric vector potential (Berry connection) arises. As result, an intrinsic angular momentum occurs even nondegenerate modes and absence of external probes. The vibronic can then seen elementary quantum particles carrying sizeable...
