Phononic Topological States in 1D Quasicrystals
J. R. M. Silva, M. S. Vasconcelos, D. H. A. L. Anselmo +1
We theoretically analyze the spectrum of phonons of a one-dimensional quasiperiodic lattice. We simulate the quasicrystal from the classic system of spring-bound atoms with a force…
Logarithm corrections in the critical behavior of the Ising model on a triangular lattice modulated with the Fibonacci sequence
T. F. A. Alves, G. A. Alves, M. S. Vasconcelos
We investigated the critical behavior of the Ising model in a triangular lattice with ferro and anti-ferromagnetic interactions modulated by the Fibonacci sequence, by using finite…
Critical behavior of the 2D Ising model modulated by the Octonacci sequence
G. A. Alves, M. S. Vasconcelos, T. F. A. Alves
We investigated the Ising model on a square lattice with ferro and antiferromagnetic interactions modulated by the quasiperiodic Octonacci sequence in both directions of the lattic…
Influence of the Terbium film size for the magnetocaloric effect at low temperatures
V. D. Mello, D. H. A. L. Anselmo, M. S. Vasconcelos +1
Significative enhance in magnetocaloric effect due to finite size and surface effects is reported in Terbium(Tb) thin films in the helimagnetic phase (corresponding to a temperatur…
Octonacci Photonic Crystals with Negative Refraction Index Materials
E. R. Brandao, M. S. Vasconcelos, D. H. A. L. Anselmo
We investigate the optical transmission spectra for -polarized (TE) and -polarized (TM) waves in one-dimensional photonic quasicrystals on a quasiperiodic multilayer structur…
Magnetic Phases and Specific Heat of Ultra-Thin Holmium Films
L. J. Rodrigues, V. D. Mello, D. H. A. L. Anselmo +1
We report model calculations of the magnetic phases of very thin Ho films in the temperature interval between 20K and 132K, and show that slab size, surface effects and magnetic fi…
