Heat conduction in a chain of harmonic and anharmonic oscillators under the presence of an energy conserving noise
(Águas de Lindóia, 2014-01-28)
Reproducing Fourier's law of heat conduction from a microscopic stochastic model is a long standing challenge in statistical physics. As was shown by Rieder, Lebowitz and Lieb many years ago, a chain of harmonically coupled ...
Static kinks in chains of interacting atoms
(Molecular Diversity Preservation International, 2020-05-13)
We theoretically analyse the equation of topological solitons in a chain of particles interacting via a repulsive power-law potential and confined by a periodic lattice. Starting from the discrete model, we perform a ...
Fashion Law e a disseminação do trabalho análoga à escravidão: a prática do Law Shopping como facilitador para violação de direitos
(Universidade Federal de Santa MariaBrasilUFSMCentro de Ciências Sociais e Humanas, 2023-07-11)
The present work aims to verify the effects of the practice of law shopping by multinational
companies on society and its contribution to violations of rights and the suppression of
constitutional guarantees, more ...
Renyi entropy and parity oscillations of anisotropic spin-s Heisenberg chains in a magnetic field
(AMER PHYSICAL SOC, 2011)
Using the density matrix renormalization group, we investigate the Renyi entropy of the anisotropic spin-s Heisenberg chains in a z-magnetic field. We considered the half-odd-integer spin-s chains, with s = 1/2, 3/2, and ...
The thermodynamic cost of driving quantum systems by their boundaries
(2015)
The laws of thermodynamics put limits to the efficiencies of thermal machines. Analogues of these laws are now established for quantum engines weakly and passively coupled to the environment providing a framework to find ...

Magnetic investigations on liquid crystalline metallopolymers
(GORDON BREACH SCI PUBL LTD, 1995)
In this contribution, magnetic investigations on materials, which essentially combine mesogenic and polymeric properties, were presented. In the glassy and the smectic phase of a copper(II) containing polymer we observed ...
Análise de riscos envolvendo motosserristas de uma empresa de reflorestamento da região sul do Brasil
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2013-12-13)
Brazil is among the countries with the largest areas planted eucalyptus in the world and the most pervasive means for your cut is semi-mechanized with the use of chainsaws. The forest cut is set with an activity subject ...
A (in)constitucionalidade da quebra do sigilo bancário pela Administração Tributária – art. 6º da LC nº 105/2001
(Universidade Federal de Santa MariaCentro de Ciências Sociais e Humanas, 2012-12-17)
The interest on bank secrecy and it's implications on law are elements
that populate the doctrinal and jurisprudential discussions. The issue of
Complementary Law. º 105/2001 brought new dimensions to the issue, as ...
