Dynamical quantum typicality: Simple method for investigating transport properties applied to the Holstein model
Petar Mitrić
We investigate the transport properties of the Holstein model using the numerically exact quantum typicality (QT) approach. Roughly speaking, QT exploits the fact that even a singl…

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…

Spectral Functions of the Holstein Polaron: Exact and Approximate Solutions
Petar Mitrić, Veljko Janković, Nenad Vukmirović +1
It is generally accepted that the dynamical mean field theory gives a good solution of the Holstein model, but only in dimensions greater than two. Here, we show that this theory,…
