Passing current through touching molecules
Guillaume Schull, Thomas Frederiksen, Mads Brandbyge +1
The charge flow from a single C60 molecule to another one has been probed. The conformation and electronic states of both molecules on the contacting electrodes have been character…
Lattice modulation spectroscopy of strongly interacting bosons in disordered and quasi-periodic optical lattices
G. Orso, A. Iucci, M. A. Cazalilla +1
We compute the absorption spectrum of strongly repulsive one-dimensional bosons in a disordered or quasi-periodic optical lattice. At commensurate filling, the particle-hole resona…
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…
Ultracold Gases of Ytterbium: Ferromagnetism and Mott States in an SU(6) Fermi System
M. A. Cazalilla, A. F. Ho, M. Ueda
It is argued that ultracold quantum degenerate gas of ytterbium Yb atoms having nuclear spin exhibits an enlarged SU symmetry. Within the Landau Fermi liquid…
Quasiparticles for quantum dot array in graphene and the associated Magnetoplasmons
Oleg L. Berman, Godfrey Gumbs, P. M. Echenique
We calculate the low-frequency magnetoplasmon excitation spectrum for a square array of quantum dots on a two-dimensional (2D) graphene layer. The confining potential is linear in…
