First we numerically study the effects 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.展开更多
We study the scalar and fermionic retarded Green's function on the background with hyperscMing violation by means of the prescriptions proposed in [J. High Eergy Phys. 09 (2002) 042; Fortsch.

High Eergy Phys. 09 (2002) 042; Fortsch. Phys. 57 (2009) 367]. For scalar field, we consider both massless and massive cases, and for spinor field, we further calculate the finite temperature correlator with the black hole background.展开更多
