Two-dimensional electron gas in a periodic potential and external magnetic field: states of pairs and three-particle systems
Wojciech Florek
The group-theoretical classification of states of identical particle pairs is presented. Then obtained states are coupled with those of an antiparticle to construct states of a thr…
On the Crossover from BCS Superconductivity to Bose Condensation
R. Micnas
We outline a microscopic approach to the superconducting fluctuations and pairing correlations in the attractive Hubbard model above Tc, using the functional integral method. A cro…
Kondo effect in quantum dots coupled to ferromagnetic leads
J. Martinek, Y. Utsumi, H. Imamura +4
We study the Kondo effect in a quantum dot which is coupled to ferromagnetic leads and analyse its properties as a function of the spin polarization of the leads. Based on a scalin…
Non-Ergodicity of the 1D Heisenberg Model
M. Bak, A. Avella, F. Mancini
The relevance of zero-energy functions, coming from zero-energy modes and present in the structure of bosonic Green's functions, is often underestimated. Usually, their values are…
Multiparty d-dimensional quantum information splitting
Andrzej Grudka, Antoni Wojcik
Generalization of quantum information splitting protocol from qubits to qudits (quantum d-dimensional systems) is presented.
