Vertex corrections to conductivity in the Holstein model: A numerical-analytical study
Veljko Janković, Petar Mitrić, Darko Tanasković +1
The optical-conductivity profile carries information on electronic dynamics in interacting quantum many-body systems. Its computation is a formidable task that is usually approache…
Optical conductivity and vibrational spectra of the narrow-gap semiconductor FeGa
C. Martin, V. A. Martinez, M. Opačić +11
Intermetallic narrow-gap semiconductors have been intensively explored due to their large thermoelectric power at low temperatures and a possible role of strong electronic correlat…
Cumulant expansion in the Holstein model: Spectral functions and mobility
Petar Mitrić, Veljko Janković, Nenad Vukmirović +1
We examine the range of validity of the second-order cumulant expansion (CE) for the calculation of spectral functions, quasiparticle properties, and mobility of the Holstein polar…
