Why polar excitons stay sharp: parity protection of the center-of-mass recoil channel in exciton-phonon scattering
Michael O. Atambo
In polar semiconductors the Fröhlich interaction is the dominant electron--phonon coupling, yet excitonic resonances in materials such as halide perovskites remain anomalously shar…
Mass-asymmetry-controlled exciton dressing and dissociation in a quantum lattice model
Michael O. Atambo
In a polar material, a neutral exciton couples to phonons through the sum of the electron and hole deformation potentials. Because the total source vanishes by charge neutrality, t…
Splicing an exact local self-energy into : tests on small Hubbard clusters
Michael O. Atambo
+DMFT-type schemes replace the local part of a self-energy by a separately computed local self-energy. A causal double counting removes a non-causal term from the hybridiz…
Accidental accuracy and vertex corrections in : Exact benchmarks for the extended Hubbard model
Michael O. Atambo
The approximation is the standard tool for quasiparticle predictions in materials, yet its regime of validity in correlated systems remains poorly quantified, because \textit{…
