Dissipation as a mechanism of energy gain

Abstract: Some properties of the annular billiard under the presence of weak dissipation are studied. We show, in a dissipative system, that the average energy of a particle acquires higher values than its average energy of the conservative case. The creation of attractors, associated with a chaotic dynamics in the conservative regime, both in appropriated regions of the phase space, constitute a generic mechanism to increase the average energy of dynamical systems.

“…This study is a natural sequence of previous papers [3,4,[20][21][22][23], but in the present work, we now consider a charged particle, which beyond being subject to the dynamic conditions of the PAB, is also subjected to the action of a constant magnetic field perpendicularly orientated in relation to the plane of the billiard. This system will be called as magnetic pulsating annular billiard (MPAB).…”

“…Uma vez estabelecido o modelo, em outro estudo foi abordado os efeitos de dissipação causado por colisões inelásticas da partícula com a fronteira [29]. Como resultado principal, nós apontamos a possibilidade de adquirir um ganho de energia médio através de fracas dissipações no sistema.…”

“…Alguns trabalhos reportam sobre a minimização ou eliminação dos efeitos dissipativos [19,20], enquanto outros tiram vantagens de sua presença [21,22]. Diferentes abordagens para os efeitos dissipativos em bilhares, foram estudadas em [29,23,24] A seção posterior, apresenta a motivação dessa dissertação como uma consequência de trabalhos desenvolvido anteriormente. As seções 1.2 e 1.3, abordam de uma maneira geral sobre o que são bilhares e a visualização da dinâmica completa por um espaço de configuração, respectivamente.…”
