Interface States in Carbon Nanotube Junctions: Rolling up graphene
H. Santos, A. Ayuela, W. Jaskólski +2
We study the origin of interface states in carbon nanotube intramolecular junctions between achiral tubes. By applying the Born-von Karman boundary condition to an interface betwee…
Dynamic Jahn-Teller effect in electron transport through single C60 molecules
T. Frederiksen, K. J. Franke, A. Arnau +3
Scanning tunneling spectra on single C60 molecules that are sufficiently decoupled from the substrate exhibit a characteristic fine structure, which is explained as due to the dyna…
Inelastic quantum transport: the self-consistent Born approximation and correlated electron-ion dynamics
Eunan J. McEniry, Thomas Frederiksen, Tchavdar N. Todorov +2
A dynamical method for inelastic transport simulations in nanostructures is compared with a steady-state method based on non-equilibrium Green's functions. A simplified form of the…
Ab initio study of transport properties in defected carbon nanotubes: an O(N) approach
Blanca Biel, F. J. Garcia-Vidal, Angel Rubio +1
A combination of ab initio simulations and linear-scaling Green's functions techniques is used to analyze the transport properties of long (up to one micron) carbon nanotubes with…
Unified description of inelastic propensity rules for electron transport through nanoscale junctions
Magnus Paulsson, Thomas Frederiksen, Hiromu Ueba +2
We present a method to analyze the results of first-principles based calculations of electronic currents including inelastic electron-phonon effects. This method allows us to deter…
Edge excitations and Topological orders in rotating Bose gases
M. A. Cazalilla, N. Barberan, N. R. Cooper
The edge excitations and related topological orders of correlated states of a fast rotating Bose gas are studied. Using exact diagonalization of small systems, we compute the energ…
