Gaussian time-dependent variational principle for the finite-temperature anharmonic lattice dynamics
Jae-Mo Lihm, Cheol-Hwan Park
The anharmonic lattice is a representative example of an interacting bosonic many-body system. The self-consistent harmonic approximation has proven versatile for the study of the…

General, Strong Impurity-Strength Dependence of Quasiparticle Interference
Seung-Ju Hong, Jae-Mo Lihm, Cheol-Hwan Park
Quasiparticle interference (QPI) patterns in momentum space are often assumed to be independent of the strength of the impurity potential when compared with other quantities, such…

Phonon-induced renormalization of electron wave functions
Jae-Mo Lihm, Cheol-Hwan Park
The Allen-Heine-Cardona theory allows us to calculate phonon-induced electron self-energies from first principles without resorting to the adiabatic approximation. However, this th…
