Impurity effects in twisted carbon nanotubes
Yuriy G. Pogorelov, Volodymyr Turkowski, Vadim M. Loktev
We consider electronic spectra of twisted carbon nanotubes and their perturbation by impurity atoms absorbed at different positions on nanotube surface within the framework of Ande…
Impurity effects on Dirac modes in graphene armchair nanoribbons
Yuriy G. Pogorelov, Vadim M. Loktev
We consider finite ribbons of graphene with armchair orientation of their edges to study in detail impurity effects on specific Dirac-like modes. In the framework of Anderson hybri…
General solution vs spin invariant eigenstates of the Dirac equation with the Coulomb potential
L. S. Brizhik, A. A. Eremko, V. M. Loktev
Solutions of the Dirac equation for an electron in the Coulomb potential are obtained using operator invariants of the equation, namely the Dirac, Johnson-Lippmann and recently fou…
On the theory of ideal Bose-gas at a finite particle number
A. I. Bugrij, V. M. Loktev
The ideal Bose-gas with finite number of particles is investigated. The exact expressions for the partition functions and occupation numbers in the grand canonical, canonical a…
General solution of the Dirac equation with the Coulomb potential
A. A. Eremko, L. Brizhik, V. M. Loktev
The Dirac equation with the Coulomb potential is studied. It is shown that there exists a new invariant in addition to the known Dirac and Johnson-Lippman ones. The solution of the…
Orbital susceptibility of T-graphene: Interplay of high-order van Hove singularities and Dirac cones
D. O. Oriekhov, V. P. Gusynin, V. M. Loktev
Square-octagon lattice underlies the description of a family of two-dimensional materials such as tetragraphene. In the present paper we show that the tight-binding model of square…
