Thermal entanglement in a triple quantum dot system
M. Urbaniak, S. B. Tooski, A. Ramsak +1
We present studies of thermal entanglement of a three-spin system in triangular symmetry. Spin correlations are described within an effective Heisenberg Hamiltonian, derived from t…
Transport in T-shaped ballistic junction
M. Bek, B. R. Bułka, J. Wróbel
We present studies of ballistic transport in three terminal T-shaped junction in a linear and non-linear regime. The floating electrode acts as a scatterer and modifies the conduct…
Study of transport properties of a molecular junction as a function of distance between the leads
Victor M. Garcia-Suarez, Tomasz Kostyrko, Steven Bailey +2
We consider a model of a molecular junction made of BDT (benzene dithiol) molecule trapped between two Au(100) leads. Using the ab initio approach implemented in the SIESTA package…
Spin effects in ferromagnetic single-electron transistors
J. Barnas, J. Martinek, G. Michalek +2
Electron tunneling in ferromagnetic single-electron transistors is considered theoretically in the sequential tunneling regime. A new formalism is developed, which operates in a tw…
Shot noise in ferromagnetic single electron tunneling devices
B. R. Bulka, J. Martinek, G. Michalek +1
Frequency dependent current noise in ferromagnetic double junctions with Coulomb blockade is studied theoretically in the limit of sequential tunneling. Two different relaxation pr…
