Gravitational wave background from neutron star phase transition
J. C. N. de Araujo, G. F. Marranghello
We study the generation of a stochastic gravitational wave (GW) background produced by a population of neutron stars (NSs) which go over a hadron-quark phase transition in its inne…
On Universality in Human Correspondence Activity
R. Dean Malmgren, Daniel B. Stouffer, Andriana S. L. O. Campanharo +1
Identifying and modeling patterns of human activity has important ramifications in applications ranging from predicting disease spread to optimizing resource allocation. Because of…
Inflationary potentials in DBI models
Dennis Bessada, William H. Kinney, Konstantinos Tzirakis
We study DBI inflation based upon a general model characterized by a power-law flow parameter and speed of sound , where and are constant…
Spin-size disorder model for granular superconductors with charging effects
Enzo Granato, Giancarlo Jug
A quantum pseudo-spin model with random spin sizes is introduced to study the effects of charging-energy disorder on the superconducting transition in granular superconducting mate…
Stokes imaging of AM Her systems using 3D inhomogeneous models - I. Description of the code and an application to V834 Cen
J. E. R. Costa, C. V. Rodrigues
Polars (or AM Her systems) are cataclysmic variables without a disc due to the strong magnetic field of the white dwarf. Most of their emission comes from the region where the accr…
Thermal fluctuations and phase diagrams of the phase field crystal model with pinning
J. A. P. Ramos, E. Granato, C. V. Achim +3
We study the influence of thermal fluctuations in the phase diagram of a recently introduced two-dimensional phase field crystal model with an external pinning potential. The model…
