Wealth distribution and Pareto's law in the Hungarian medieval society
G. Hegyi, Z. Neda, M. A. Santos
The distribution of wealth in the Hungarian medieval aristocratic society is reported and studied. The number of serf families belonging to a noble is taken as a measure of the cor…
Disorder Induced Localized States in Graphene
Vitor M. Pereira, F. Guinea, J. M. B. Lopes dos Santos +2
We consider the electronic structure near vacancies in the half-filled honeycomb lattice. It is shown that vacancies induce the formation of localized states. When particle-hole sy…
Macroscopic thermal entanglement due to radiation pressure
A. Ferreira, A. Guerreiro, V. Vedral
Can entanglement and the quantum behavior in physical systems survive at arbitrary high temperatures? In this Letter we show that this is the case for a electromagnetic field mode…
Analytical study of tunneling times in flat histogram Monte Carlo
Miguel D. Costa, J. Viana Lopes, J. M. B. Lopes dos Santos
We present a model for the dynamics in energy space of multicanonical simulation methods that lends itself to a rather complete analytic characterization. The dynamics is completel…
Ranking Pages by Topology and Popularity within Web Sites
Jose Borges, Mark Levene
We compare two link analysis ranking methods of web pages in a site. The first, called Site Rank, is an adaptation of PageRank to the granularity of a web site and the second, call…
The Spectra of Lamplighter Groups and Cayley Machines
Mark Kambites, Pedro V. Silva, Benjamin Steinberg
We calculate the spectra and spectral measures associated to random walks on restricted wreath products of finite groups with the infinite cyclic group, by calculating the Kesten-v…
