Symmetry restrictions in the chirality dependence of physical properties of single-wall nanotubes

, 2006
We investigate the chirality dependence of physical properties of nanotubes which are wrapped by the planar hexagonal lattice including graphite and boron nitride sheet, and reveal its symmetry origin.

Magnetoelectronic properties of graphene dressed by a high-frequency field

, 2016
Solving the Schrödinger problem for electrons in graphene subjected to both a stationary magnetic field and a strong high-frequency electromagnetic wave (dressing field), we found that the dressing field drastically changes the structure of Landau levels

Physical mechanisms relevant to flow resistance in textured microchannels [PDF]

, 2017
Flow resistance of liquids flowing through microchannels can be reduced by replacing flat, no-slip boundaries with boundaries adjacent to longitudinal grooves containing an inert gas, resulting in apparent slip.

Magnetic properties of a two-dimensional electron gas strongly coupled to light

, 2016
Considering the quantum dynamics of two-dimensional electron gas (2DEG) exposed to both a stationary magnetic field and an intense high-frequency electromagnetic wave, we found that the wave decreases the scattering-induced broadening of Landau levels ...
