A diagrammatic description of the equations of motion, current, and noise within the second-order von Neumann approach
O. Karlström, C. Emary, P. Zedler +5
We investigate the second-order von Neumann approach from a diagrammatic point-of-view and demonstrate its equivalence with the resonant tunneling approximation. Investigation of h…
Canyon of Current Suppression in an interacting two-level Quantum Dot
O. Karlström, J. N. Pedersen, P. Samuelsson +1
Motivated by the recent discovery of a canyon of conductance suppression in a two-level equal spin quantum dot system [Phys. Rev. Lett. , 186804 (2010)] the transport thr…
Correlation-induced conductance suppression at level degeneracy in a quantum dot
H. A. Nilsson, O. Karlström, M. Larsson +6
The large, level-dependent g-factors in an InSb nanowire quantum dot allow for the occurrence of a variety of level crossings in the dot. While we observe the standard conductance…
Bubble coalescence in breathing DNA: Two vicious walkers in opposite potentials
Tomas Novotny, Jonas Nyvold Pedersen, Tobias Ambjornsson +2
We investigate the coalescence of two DNA-bubbles initially located at weak segments and separated by a more stable barrier region in a designed construct of double-stranded DNA. T…
