Principles of thermal design with nematic liquid crystals
S. Fumeron, E. Pereira, F. Moraes
Highly engineered materials are arousing great interest because of their ability to manipulate heat, as described by coordinate transformation approach. Based on the recently devel…
Inertial-Hall effect: the influence of rotation on the Hall conductivity
Julio E. Brandão, F. Moraes, M. M. Cunha +2
Inertial effects play an important role in classical mechanics but have been largely overlooked in quantum mechanics. Nevertheless, the analogy between inertial forces on mass part…
Indirect band gap in graphene from modulation of the Fermi velocity
Jonas R. F. Lima, F. Moraes
In this work we study theoretically the electronic properties of a sheet of graphene grown on a periodic heterostructure substrate. We write an effective Dirac equation, which incl…
Effects of rotation in the energy spectrum of
Jonas R. F. Lima, Julio Brandao, Marcio M. Cunha +1
In this paper, motivated by the experimental evidence of rapidly rotating molecules in fullerite, we study the low-energy electronic states of rotating fullerene within a…
Landau levels, self-adjoint extensions and Hall conductivity on a cone
A. Poux, L. R. S. Araujo, C. Filgueiras +1
In this work we obtain the Landau levels and the Hall conductivity at zero temperature of a two-dimensional electron gas on a conical surface. We investigate the integer quantum Ha…
Metric approach for sound propagation in nematic liquid crystals
E. Pereira, S. Fumeron, F. Moraes
In the eikonal approach, we describe sound propagation near to topological defects of nematic liquid crystal as geodesics of a non-euclidian manifold endowed with an effective metr…
