Description:
Author(s): Yue Chen (陈粤), Xinyuan Ai (艾馨元), and C. A. Marianetti Here we introduce a new approach to compute the finite temperature lattice dynamics from first principles via the newly developed slave mode expansion. We study PbTe where inelastic neutron scattering reveals strong signatures of nonlinearity as evidenced by anomalous features which emerge in the ph... [Phys. Rev.
