Query: Holographic insulator/superconductor phase transition in Born-Infeld
  electrodynamics   We studied holographic insulator/superconductor phase transition in the
framework of Born-Infeld electrodynamics both numerically and analytically.
First we numerically study the effects of the Born-Infeld electrodynamics on
the phase transition, find that the critical chemical potential is not changed
by the Born-Infeld parameter. Then we employ the variational method for the
Sturm-Liouville eigenvalue problem to analytically study the phase transition.
The analytical results obtained are found to be consistent with the numerical
results.
