Implementation of transmission functions for an optimized three-terminal quantum dot heat engine

Christian H. Schiegg, Michael Dzierzawa, Ulrich Eckern

We consider two modifications of a recently proposed three-terminal quantum dot heat engine. First, we investigate the necessity of the thermalization assumption, namely that elect…

Spin-charge coupled dynamics driven by a time-dependent magnetization

Sebastian Tölle, Ulrich Eckern, Cosimo Gorini

The spin-charge coupled dynamics in a thin, magnetized metallic system are investigated. The effective driving force acting on the charge carriers is generated by a dynamical magne…

Magnetic state of Nb(1-7nm)/CuNi(6nm) superlattices revealed by Polarized Neutron Reflectometry and SQUID magnetometry

Yu. Khaydukov, R. Morari, D. Lenk +11

We report results of a magnetic characterization of [CuNi(6nm)] (x=1-7nm) superlattices using Polarized Neutron Reflectometry (PNR) and SQUID magnetometry. The…

Efficient creation of dipolar coupled nitrogen-vacancy spin qubits in diamond

Ingmar Jakobi, Seyed Ali Momenzadeh, Felipe Fávaro de Oliveira +6

Coherently coupled pairs or multimers of nitrogen-vacancy defect electron spins in diamond have many promising applications especially in quantum information processing (QIP) but a…

Chiral interface states in graphene - junctions

L. Cohnitz, A. De Martino, W. Häusler +1

We present a theoretical analysis of unidirectional interface states which form near - junctions in a graphene monolayer subject to a homogeneous magnetic field. The semiclas…

Theory of invariants-based formulation of Hamiltonians with application to strained zinc-blende crystals

Johannes Wanner, Ulrich Eckern, Karl-Heinz Höck

Group theoretical methods and theory are combined to determine spin-dependent contributions to the effective conduction band Hamiltonian. To obtain the consta…
