We consider the adsorbed benzene monolayer on graphene and show that the monolayer’s structure can be very complicated even for benzene, the simplest representative of the cyclic hydrocarbons. We base this on previous the first principal investigat

Structural phases in crystal BEDT-TTF under the influence of doping molecules were studied. The system demonstrates the transition from a parallel aligned molecular phase (β-phase) to a new equilibrium state, where the molecules are rotated at a cer

The simple model that can describe structure and charge ordering in complex doped organic crystals is proposed. We consider the quasione-dimensional model of a crystal with chains (stacks) of flat BEDT-TTF molecules. In a chain of large molecules, sm

The functionalization (adsorption) of graphene and carbon nanotubes (CNT) is investigated in the case of charge transfer between a functionalizing molecule (adatom) and a substrate (graphenes or CNT), and the first principles charge transfer calculat

The 180 $$^{\circ }$$ twin boundary (stacking fault) is investigated in the hexagonal close-packed (hcp) lattice. It is shown that the interatomic interaction between neighbors within the boundary lowers symmetry as compared with that in hcp phase. A

The phase transition between bcc and hcp in solid 4He has martensitic-like features. The phase transition was investigated theoretically in terms of coherent lattice transformations. A theory with three order parameters is developed to take into acco

Ferroelectric-ferromagnet with inhomogeneous exchange-relativistic magneto-electric interaction (Dzyaloshinskii-Moriya) is studied theoretically in external electric field. The domain wall combines properties of usual 180° one in ferroelectric and u

The mechanism of transition between bcc and hcp phases, which is applicable to both classical and quantum crystals, has been considered at the microscopic level. The relative orientations of the lattices that provide coherent phase matching are speci
