Stability and optoelectronic properties of oligothiophene molecules confined in boron-nitride nanotubes : A many-body theoretical approach
Xavier Blase, Mauricio Rodriguez-Mayorga, Ivan Duchemin
We investigate the structural and optoelectronic properties of oligothiophene (nT) molecules encapsulated in boron-nitride (BN) nanotubes using density functional theory, many-body…

Efficient analytic continuation approach to Bethe-Salpeter excitation spectra in selected energy windows
Ivan Duchemin, Xavier Blase
We explore the merits of building the Bethe-Salpeter absorption spectrum in a specific energy range using analytic continuation techniques. Specifically, we calculate iteratively a…
