Effect of dark energy on Hawking–Page transition

Publication date: January 2020Source: Physics of the Dark Universe, Volume 27Author(s): Yao Wu, Wei XuAbstractIt is well known that there exists a Hawking–Page (HP) transition between Schwarzschild-AdS (SAdS) black hole and the thermal AdS vacuum. In this paper, we study a similar phase transition under the effect of dark energy, namely HP transition of AdS black hole surrounded by quintessence dark energy. It is shown that there always exists a HP transition between the quintessence AdS (qAdS) black hole and the thermal AdS vacuum. In contrast to Einstein gravity, we find that the high temperature phase can be dominated either by the qAdS black hole or the thermal AdS vacuum depending on the constants of quintessence dark energy, including the constant ωq for the equation of state and the constant a for the density of quintessence. The a−ωq parameter space for physical HP transition is presented. Besides, a always diminishes the HP temperature; while ωq enlarges the HP temperature when −1

Authors: Lisicki M, Schoenen J Abstract Introduction: Most preventive migraine treatments modify the brain's excitation/inhibition balance and/or serotonin metabolism, which likely accounts for their unfavourable adverse effect profile. Novel biological therapies blocking CGRP transmission are effective and much better tolerated, but they are expensive and may not influence brain dysfunctions upstream in the pathophysiological cascade of migraine, including premonitory and aura symptoms. Biochemical and clinical studies suggest that there may be another complimentary treatment strategy, the one that targets the undere...
