非相对论性物质在Hoenava-Lifshitz引力中的凝聚

Condensation for non-relativistic matter in Hořava-Lifshitz gravity

Jiliang Jing, Songbai Chen, Qiyuan Pan

摘要:

本文研究了在没有细致平衡条件下的Hoenava-Lifshitz黑洞中非相对论性物质的凝聚。结果表明,对于固定的非相对论性参数$α_2$(或详细的平衡参数$ε$),随着参数$ε$(或$α_2$)的增大,标量头发更容易形成,但凝聚不受非相对论性参数$β_2$的影响.我们还发现电导率的带隙频率与临界温度的比值随$ε$和$α_2$的增加而减小,随$β_2$的增加而增大。在相对论性物质满足细致平衡的条件下,该比值可归约为Einstein引力中的Horowitz-Roberts关系式$ω_g/T_c\approx 8$和Cai在Hoenava-Lifshitz引力中的结果$ω_g/T_c\approx 13$。特别是,我们注意到通过适当地选取$ε$,$α_2$,$β_2$和$m$的值,该比值可以达到BCS理论的值$ω_g/T_c\approx 3.5$.

英文摘要:

We study condensation for non-relativistic matter in a Hořava-Lifshitz black hole without the condition of the detailed balance. We show that, for the fixed non-relativistic parameter $α_2$ (or the detailed balance parameter $ε$), it is easier for the scalar hair to form as the parameter $ε$ (or $α_2$) becomes larger, but the condensation is not affected by the non-relativistic parameter $β_2$. We also find that the ratio of the gap frequency in conductivity to the critical temperature decreases with the increase of $ε$ and $α_2$, but increases with the increase of $β_2$. The ratio can reduce to the Horowitz-Roberts relation $ω_g/T_c\approx 8$ obtained in the Einstein gravity and Cai's result $ω_g/T_c\approx 13$ found in a Hořava-Lifshitz gravity with the condition of the detailed balance for the relativistic matter. Especially, we note that the ratio can arrive at the value of the BCS theory $ω_g/T_c\approx 3.5$ by taking proper values of $ε$, $α_2$, $β_2$ and $m$.
