Molecular dynamics simulation of the self-retracting motion of a graphene flake
Andrei M. Popov, Irina V. Lebedeva, Andrey A. Knizhnik +2
The self-retracting motion of a graphene flake on a stack of graphene flakes is studied using molecular dynamics simulations. It is shown that in the case when the extended flake i…
Can Barrier to Relative Sliding of Carbon Nanotube Walls Be Measured?
Andrey M. Popov, Yurii E. Lozovik, Evgenii K. Krivorotov
Interwall interaction energies, as well as barriers to relative sliding of the walls along the nanotube axis, are first calculated for pairs of both armchair or both zigzag adjacen…
Influence of Landau level mixing on the properties of elementary excitations in graphene in strong magnetic field
Yu. E. Lozovik, A. A. Sokolik
Massless Dirac electrons in graphene fill Landau levels with energies scaled as square roots of their numbers. Coulomb interaction between electrons leads to mixing of different La…
Collective excitations on a surface of topological insulator
D. K. Efimkin, Yu. E. Lozovik, A. A. Sokolik
We study collective excitations in a helical electron liquid on a surface of three-dimensional topological insulator. Electron in helical liquid obeys Dirac-like equation for massl…
Commensurate-incommensurate phase transition in bilayer graphene
Andrey M. Popov, Irina V. Lebedeva, Andrey A. Knizhnik +2
A commensurate-incommensurate phase transition in bilayer graphene is investigated in the framework of the Frenkel-Kontorova model extended to the case of two interacting chains of…
Phase diagram of Rydberg atoms with repulsive van der Waals interaction
O. N. Osychenko, G. E. Astrakharchik, Y. Lutsyshyn +2
We report a quantum Monte Carlo calculation of the phase diagram of bosons interacting with a repulsive inverse sixth power pair potential, a model for assemblies of Rydberg atoms…
