Joule-Thomson Expansion of d-Dimensional Charged Anti-de Sitter Black Holes Surrounded by Quintessence with a Cloud of Strings Background

Effects of the dimension on the Joule-Thomson expansion are investigated in details by considering the case of d-dimensional(d≥5)charged anti-de Sitter(AdS)black hole which is surrounded by the quintessence with a cloud of strings background.Firstly,the thermodynamic quantity of this black hole is reviewed.Secondly,three important features of the Joule-Thomson expansion in different dimensions are discussed,including the Joule-Thomson coefficients,inversion curves,and isenthalpic curves.Finally,the effects of the charge,the quintessence and strings cloud parameters on the Joule-Thomson expansion in the case of six-dimensional black hole are studied.

d维RN-AdS黑洞的弱宇宙审查猜想

阐述计算带电粒子被d维RN-AdS黑洞吸入时,视界附近的能量-动量关系,可以验证正常相空间和扩展相空间情况下黑洞的弱宇宙审查猜想是否满足。分析表明,在正常相空间中,极端黑洞和近极端黑洞的弱宇宙审查猜想均满足;另一方面,在扩展相空间中,只有极端黑洞的弱宇宙审查猜想才满足,而对于近极端d维RN-AdS黑洞受参数的影响,无法证明其弱宇宙审查猜想是否能够满足。
