Monolayer graphite films, or graphene, have quasiparticle excitations that can be described by (2+1)-dimensional Dirac theory. We demonstrate that this produces an unconventional form of theâ€¦ (More)

It is shown that in 3 + 1 dimensions, a constant magnetic field is a catalyst of dynamical chiral symmetry breaking, leading to generating a fermion mass even at the weakest attractive interactionâ€¦ (More)

It is shown that a constant magnetic field in 3+1 and 2+1 dimensions is a strong catalyst of dynamical chiral symmetry breaking, leading to the generation of a fermion dynamical mass even at theâ€¦ (More)

We consider the relationship between the tight-binding Hamiltonian of the two-dimensional honeycomb lattice of carbon atoms with nearest neighbor hopping only and the 2 + 1 dimensional Hamiltonian ofâ€¦ (More)

The quantum magnetic oscillations of electrical sShubnikovâ€“de Haas effectd and thermal conductivities are studied for graphene which represents a distinctive example of planar systems with a linear,â€¦ (More)

The intensity as well as position in energy of the absorption lines in the infrared conductivity of graphene, both exhibit features that are directly related to the Dirac nature of itsâ€¦ (More)

The latest experiments have confirmed the theoretically expected universal value Ï€e/2h of the ac conductivity of graphene and have revealed departures of the quasiparticle dynamics from predictionsâ€¦ (More)

Recent experiments have proven that the quasiparticles in graphene obey a Dirac equation. Here we show that microwaves are an excellent probe of their unusual dynamics. When the chemical potential isâ€¦ (More)

Selfconsistent equations which describe the order parameter and chemical potential behaviour in 2D metalic system as functions of external magnetic field, H, temperature, T , and carrier density, n,â€¦ (More)
