Many-body effects in TiSe2: Can GW describe an Excitonic Insulator?
M. Cazzaniga, H. Cercellier, M. Holzmann +4
We present both theoretical ab initio GW and experimental angle-resolved photoemission (ARPES) and scanning tunneling (STS) spectroscopy results on TiSe2. With respect to the densi…
Ab initio investigation of the groundstate, electronic, and optical properties of polyyne and cumulene prototypes
Carlo Motta, Marco Cazzaniga, Andrea Bordoni +1
We have investigated polyyne and cumulene prototypes based on the density-functional theory. Our independent-particle spectra show that the various carbynes can be distinguished by…
Ab-initio self-energy corrections in systems with metallic screening
Marco Cazzaniga, Nicola Manini, Luca Guido Molinari +1
The calculation of self-energy corrections to the electron bands of a metal requires the evaluation of the intraband contribution to the polarizability in the small-q limit. When n…
