• "Topographical fingerprints of many-body interference in STM junctions on thin insulating films", Donarini, Siegert, Sobczyk, Grifoni, 2012

  Publikation

  Negative differential conductance is a nonlinear transport phenomenon ubiquitous in molecular nanojunctions. Its physical origin can be the most...

• "Electronic transport properties of double-wall carbon nanotubes", Datta, Wang, Tilmaciu, Flahaut, Marty, Grifoni, Wernsdorfer, 2011

  Publikation

  We studied the discretized electronic spectra of double-wall carbon nanotube (DWCNT) quantum dots (QDs) in the Coulomb-blockade regime. At low...

• "Dynamical symmetry breaking in vibration-assisted transport through nanostructures", Yar, Donarini, Koller, Grifoni, 2011

  Publikation

  A theoretical model of a single molecule coupled to many vibronic modes is presented. At low energies, transport is dominated by electron-vibron...

• "Entanglement spectra of coupled S=1/2 spin chains in a ladder geometry", Läuchli, Schliemann, 2012

  Publikation

  We study the entanglement spectrum of spin-1/2 XXZ ladders both analytically and numerically. Our analytical approach is based on perturbation theory...

• "Spectrum and Franck--Condon factors of interacting suspended single-wall carbon nanotubes", Donarini, Yar, Grifoni, 2012

  Publikation

  A low-energy theory of suspended carbon nanotube quantum dots in weak tunnelling coupling with metallic leads is presented. The focus is on the...

• "Magnetoconductance of carbon nanotubes probed in parallel magnetic fields up to 60 T", Jhang, Marganska, del Valle, Skourski, Grifoni, Wosnitza, Strunk, 2011

  Publikation

  Magnetoconductance of carbon nanotubes (CNTs) is investigated. We clearly show that a semiconducting CNT can be converted into a metallic one, or vice...
