Excitonic effects in optical absorption and electron-energy loss spectra of hexagonal boron nitride
Ludger Wirtz, Andrea Marini, Myrta Gruning +1
A new interpretation of the optical and energy-loss spectra of hexagonal boron nitride is provided based on first-principle calculations. We show that both spectra cannot be explai…
Excited states dynamics in time-dependent density functional theory: high-field molecular dissociation and harmonic generation
Alberto Castro, M. A. L. Marques, Julio A. Alonso +2
We present a theoretical description of femtosecond laser induced dynamics of the hydrogen molecule and of singly ionised sodium dimers, based on a real-space, real-time, implement…
Substrate Interface Interactions
R. Czerw, B. Foley, D. Tekleab +3
By utilizing the current transients in scanning tunneling spectroscopy, the local interfacial electronics between multiwalled carbon nanotubes and several supporting substrates has…
Conduction mechanism and magnetotransport in multi-walled carbon nanotubes
Stephan Roche, Francois Triozon, Angel Rubio +1
We report on a numerical study of quantum diffusion over micron lengths in defect-free multi-walled nanotubes. The intershell coupling allows the electron spreading over several sh…
Solution of Poisson's equation for finite systems using plane wave methods
Alberto Castro, Angel Rubio, M. J. Stott
Reciprocal space methods for solving Poisson's equation for finite charge distributions are investigated. Improvements to previous proposals are presented, and their performance is…
Comparision of direct and Fourier space techniques in time-dependent density functional theory
G. F. Bertsch, Angel Rubio, K. Yabana
Several techniques have appeared in the literatuare to solve the equations of time-dependent density functional theory. We compare the efficiency of different methods based on mesh…
