诱导引力理论中的Baby宇宙

本文讨论诱导引力理论中Baby宇宙的量子效应.我们证明了在诱导引力理论中Baby-Parent宇宙相互作用是非定域的,并论证了在低能极限下诱导的宇宙学常数为零.这一论证并不依赖于诱导势的细节.     

Holographic Insulator/Superconductor Phase Transition in Born–Infeld Electrodynamics

We study holographic insulator/superconductor phase transition in the framework of Born–Infeld electrodynamics both numerically and analytically. First we numerically study the efects of the Born–Infeld electrodynamics on the phase transition, find that when the Born–Infeld parameter increases, the critical chemical potential keeps invariant but the gap frequency becomes larger. Then we employ the variational method for the Sturm–Liouville eigenvalue problem to study the phase transition analytically. The analytical results obtained are found to be consistent with the numerical results.
