Noise-induced quantum transport [PDF]
Physical Review E, 2005 We analyze the problem of directed quantum transport induced by external exponentially correlated telegraphic noise. In addition to quantum nature of the heat bath, nonlinearity of the periodic system potential brings in quantum contribution. We observe that quantization, in general, enhances classical current at low temperature, while the differences ...

Correlated spin transport in nanostructures: entanglement creation and spin filtering [PDF]
, 2003 The electron spin for electronics has only recently attracted much interest. The idea to use spin|as opposed to charge|as the fundamental data carrier was motivated by recent experiments that showed unusually long spindephasing times up to ...

Quantum State of the Fermionic Carriers in a Transport Channel Connecting Particle Reservoirs
Condensed Matter, 2019 We analyze the quantum state of fermionic carriers in a transport channel attached to a particle reservoir. The analysis is done from first principles by considering microscopic models of the reservoir and transport channel.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Spin-dependent transport of interacting electrons in mesoscopic systems [PDF]
, 2007 Spin-dependent electronic transport properties of mesoscopic systems are studied using the nonequilibrium Green function formalism. In the first part we examine the influence of short-range electron-electron interactions on the conductance of quantum ...

Experimental control of transport resonances in a coherent quantum rocking ratchet
Nature Communications, 2016 The ratchet effect can be used as a tool to control coherent quantum transport of ultra-cold atoms. Here, the authors demonstrate a rocking quantum ratchet with a rubidium BEC, and reveal the existence of quantum transport resonances.

Discerning protein pools by selective staining with self‐labeling tags
FEBS Letters, EarlyView.Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

Investigation of carbon nanotube quantum dots connected to ferromagnetic leads [PDF]
, 2015 The implementation of ferromagnetic contacts in complex nanoelectronic devices, e.g. in spin-valves bears great potential for applications and fundamental investigations. Spin-valves are structures with two magnetic contacts and a non-magnetic medium (
