Diatomic molecule as a quantum entanglement switch
Adam Rycerz
We investigate a pair entanglement of electrons in diatomic molecule, modeled as a correlated double quantum dot attached to the leads. The low-temperature properties are derived f…
The combined exact diagonalization - ab initio approach and its application to correlated electronic states and Mott-Hubbard localization in nanoscopic systems
J. Spalek, E. M. Gorlich, A. Rycerz +1
We overview the EDABI method developed recently and combining the exact diagonalization and ab initio aspects of electron states in correlated systems and apply it to nanoscopic sy…
Electronic structure and parity effects in correlated nanosystems
Adam Rycerz, Jozef Spalek
We discuss the spectral, transport and magnetic properties of quantum nanowires composed of N\leq 13 atoms and containing either even or odd numbers of valence electrons. In our ap…
Conductance of a double quantum dot with correlation-induced wave function renormalization
Adam Rycerz, Jozef Spalek
The zero-temperature conductance of diatomic molecule, modelled as a correlated double quantum dot attached to noninteracting leads is investigated. We utilize the Rejec-Ramsak for…
Entanglement and transport through correlated quantum dot
Adam Rycerz
We study quantum entanglement in a single-level quantum dot in the linear-response regime. The results show, that the maximal quantum value of the conductance 2e^2/h not always mat…
Fundamental properties, localization threshold, and the Tomonaga--Luttinger behavior of electrons in nanochains
Adam Rycerz, Jozef Spalek
We provide a fairly complete discussion of electronic properties of nanochains modelling the simplest quantum nanowires, within the recently proposed approach combining Exact Diago…
