Thermopower signatures and spectroscopy of the canyon of conductance suppression

G. Kiršanskas, S. Hammarberg, O. Karlström +1

Interference effects in quantum dots between different transport channels can lead to a strong suppression of conductance, which cuts like a canyon through the common conductance p…

Understanding the length dependence of molecular junction thermopower

Olov Karlström, Mikkel Strange, Gemma C. Solomon

Thermopower of molecular junctions is sensitive to details in the junction and may increase, decrease, or saturate with increasing chain length, depending on the system. Using McCo…

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…

Total Current Blockade in an Ultra-Cold Dipolar Quantum Wire

Líney Halla Kristinsdóttir, Olov Karlström, Johannes Bjerlin +4

Cold atom systems offer a great potential for the future design of new mesoscopic quantum systems with properties that are fundamentally different from semiconductor nanostructures…

Increasing thermoelectric performance using coherent transport

Olov Karlstrom, Heiner Linke, Gunnar Karlstrom +1

We show that coherent electron transport through zero-dimensional systems can be used to tailor the shape of the system's transmission function. This quantum-engineering approach c…

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…
