Mott transition in the Hubbard model on anisotropic honeycomb lattice with implications for strained graphene: Gutzwiller variational study
Grzegorz Rut, Maciej Fidrysiak, Danuta Goc-Jagło +1
Modification of interatomic distances due to high pressure leads to exotic phenomena, including metallicity, superconductivity and magnetism, observed in materials not showing such…
Conductivity scaling and the effects of symmetry-breaking terms in bilayer graphene Hamiltonian
Dominik Suszalski, Grzegorz Rut, Adam Rycerz
We study the ballistic conductivity of bilayer graphene in the presence of symmetry-breaking terms in effective Hamiltonian for low-energy excitations, such as the trigonal-warping…
Mesoscopic valley filter in graphene Corbino disk containing a p-n junction
Dominik Suszalski, Grzegorz Rut, Adam Rycerz
The Corbino geometry allows one to investigate the propagation of electric current along a p-n interface in ballistic graphene in the absence of edge states appearing for the famil…
Thermoelectric properties of gapped bilayer graphene
Dominik Suszalski, Grzegorz Rut, Adam Rycerz
Unlike in conventional semiconductors, both the chemical potential and the band gap in bilayer graphene (BLG) can be tuned via application of external electric field. Among numerou…
Lifshitz transition and thermoelectric properties of bilayer graphene
Dominik Suszalski, Grzegorz Rut, Adam Rycerz
This is a numerical study of thermoelectric properties of ballistic bilayer graphene in the presence of trigonal warping term in the effective Hamiltonian. We find, in the mesoscop…
Trigonal warping, pseudodiffusive transport, and finite-system version of the Lifshitz transition in magnetoconductance of bilayer-graphene Corbino disks
Grzegorz Rut, Adam Rycerz
Using the transfer matrix in the angular-momentum space we investigate the impact of trigonal warping on magnetotransport and scaling properties of a ballistic bilayer graphene in…
Minimal conductivity and signatures of quantum criticality in ballistic graphene bilayer
Grzegorz Rut, Adam Rycerz
We study the ballistic conductivity of graphene bilayer in the presence of next-nearest neighbor hoppings between the layers. An undoped and unbiased system was found in Ref. [1] t…
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…
Quantum-limited shot noise and quantum interference in graphene based Corbino disk
Grzegorz Rut, Adam Rycerz
This is a theoretical study of finite voltage effects on the conductance, the shot noise power, and the third charge-transfer cumulant for graphene-based Corbino disk in the presen…
Conditions for Conductance Quantization in Mesoscopic Dirac Systems on the Examples of Graphene Nanoconstrictions
Grzegorz Rut, Adam Rycerz
Ballistic transport through an impurity-free section of the Corbino disk in graphene is investigated by means of the Landauer-Büttiker formalism in the mesoscopic limit. In the lin…
Pseudodiffusive conductance, quantum-limited shot noise, and Landau-level hierarchy in biased graphene bilayer
Grzegorz Rut, Adam Rycerz
We discuss, by means of mode-matching analysis for the Dirac equation, how splittings of the Landau-level (LL) degeneracies associated with spin, valley, and layer degrees of freed…
