Bardeen-AdS黑洞的热力学混沌及暗能量效应
Thermal chaos of Bardeen-AdS black hole and effects of quintessence dark energy
摘要
Abstract
Thermal chaos under temporally/spatially periodic perturbations in the extended phase space of Bardeen-Anti de Sitter black holes surrounded by quintessence dark energy is investigated.Occurring condition of chaos is obtained with Melnikov integral.Spatial chaos is always supposed to occur even for a tiny spatially periodic perturbation imposed on equilibrium configuration.However,temporal chaos will arise in unstable spinodal region only if the given perturbed amplitude γ is larger than a critical value γc.The value of γc is determined by magnetic monopole charge β,initial temperature T0,quintessence state parameter ω,and quintessence normalization parameter a.In particular,combining effects of ω and parameter a together,we find that the function of quintessence dark energy is similar to an enhancing/damped mechanism.关键词
