Transport suppression in heterostructures driven by an ac gate voltage

Miguel Rey, Michael Strass, Sigmund Kohler +2

We explore the possibility of inducing in heterostructures driven by an ac gate voltage the coherent current suppression recently found for nanoscale conductors in oscillating fiel…

Coherence stabilization of a two-qubit gate by AC fields

Karen M. Fonseca Romero, Sigmund Kohler, Peter Hänggi

We consider a CNOT gate operation under the influence of quantum bit-flip noise and demonstrate that ac fields can change bit-flip noise into phase noise and thereby improve cohere…

Driven quantum transport on the nanoscale

Sigmund Kohler, Jörg Lehmann, Peter Hänggi

We explore the prospects to control by use of time-dependent fields quantum transport phenomena in nanoscale systems. In particular, we study for driven conductors the electron cur…

What are spin currents in Heisenberg magnets?

Florian Schuetz, Peter Kopietz, Marcus Kollar

We discuss the proper definition of the spin current operator in Heisenberg magnets subject to inhomogeneous magnetic fields. We argue that only the component of the naive "current…

Vibrational effects in laser driven molecular wires

Jörg Lehmann, Sigmund Kohler, Volkhard May +1

The influence of an electron-vibrational coupling on the laser control of electron transport through a molecular wire that is attached to several electronic leads is investigated.…
