Vibrational characterization of dinaphthylpolyynes: A model system for the study of end-capped sp carbon chains
Eugenio Cinquanta, Luca Ravagnan, Ivano Eligio Castelli +4
We perform a systematic investigation of the resonance and vibrational properties of naphthyl-terminated sp carbon chains (dinaphthylpolyynes) by combined multi-wavelength resonant…
Carbon sp chains in graphene nanoholes
Ivano E. Castelli, Nicola Ferri, Giovanni Onida +1
Nowadays sp carbon chains terminated by graphene or graphitic-like carbon are synthesized routinely in several nanotech labs. We propose an ab-initio study of such carbon-only mate…
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…
