Sub-Sharvin conductance and enhanced shot noise in doped graphene
Adam Rycerz, Piotr Witkowski
Ideal Sharvin contact in a multimode regime shows the conductance (with the conductance quantum, the Fermi momentum, and th…
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…
Pairwise entanglement and the Mott transition for correlated electrons in nanochains
Adam Rycerz
Pairwise entanglement, calculated separately for charge and spin degrees of freedom, is proposed as a ground-state signature of the Mott transition in correlated nanoscopic systems…
Wiedemann-Franz law for massless Dirac fermions with implications for graphene
Adam Rycerz
In the 2016 experiment by Crossno et al. [Science 351, 1058 (2016)], electronic contribution to the thermal conductivity of graphene was found to violate the well-known Wiedemann-F…
Magnetoconductance of the Corbino disk in graphene: Chiral tunneling and quantum interference in the bilayer case
Grzegorz Rut, Adam Rycerz
Quantum transport through an impurity-free Corbino disk in bilayer graphene is investigated analytically, by the mode-matching method for effective Dirac equation, in the presence…
Electron transport and quantum-dot energy levels in Z-shaped graphene nanoconstriction with zigzag edges
Adam Rycerz
Motivated by recent advances in fabricating graphene nanostructures, we find that an electron can be trapped in Z-shaped graphene nanoconstriction with zigzag edges. The central se…
