We examine the transport of extended and localized excitations in one-dimensional linear chains populated by linear and nonlinear symmetric identical n-mers (with n = 3, 4, 5, and 6), randomly distributed. First, we examine ...

We report on the lattice evolution of BiFeO3 as function of temperature using far infrared emissivity, reflectivity, and x-ray absorption local structure. A power law fit to the lowest frequency soft phonon in the magnetic ...

The Contact Process is a continuous-time Markov process introduced by Ted Harris as a toy model for the spread of disease on a network composed of hosts that, when infected, can either recover from the disease or spread ...

The nanostructure and the oxygen storage capacity against reactive oxygen species (ROS) are essential features to take into account during the design of a new material that will be used as the basis of novel therapeutic ...

Lattice models (tight-binding) for many-body systems give a good theoretical and experimental framework to study quantum phase transitions presented in several strongly correlated materials at low temperature. In general, ...

Las mezclas de partículas que satisfacen diferentes estadísticas han sucitado gran interes tanto teórico como experimental en la últimas decadas, debido a la posibilidad de confinar y manipular gases cuánticos en redes ...
