DOI: 10.1007/s11182-021-02279-5
Abstract: The different translational symmetry of the cuprite crystal sublattices is taken into account by unfolding the phonon spectrum from the Brillouin zone of the crystal into the Brillouin zones of the anion and metal. Such… read more here.

DOI: 10.1103/physrevb.104.064422
Abstract: We show that a collinear Heisenberg antiferromagnet, whose sublattice symmetry is broken at the Hamiltonian level, becomes a fluctuation-induced ferrimagnet at any finite temperature $T$ below the N\'eel temperature ${T}_{\mathrm{N}}$. We demonstrate this using a… read more here.

DOI: 10.1126/sciadv.1602388
Abstract: Absorption of light in hybrid perovskite solar cells leads to ultrafast large-amplitude deformations of the inorganic sublattice. Femtosecond resolution electron scattering techniques are applied to resolve the first atomic-scale steps following absorption of a photon… read more here.
