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…
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 Quasicrystals
E. R. Brandão, C. H. Costa, M. S. Vasconcelos +2
We study theoretically the transmission spectra in one-dimensional photonic quasicrystals, made up of SiO() and TiO() materials, organized following the Octonacci seq…
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…
