By introducing a pocket doping region near the source, ... More
d-Wave holographic superconductors with backreaction in external magnetic fieldsSep 19 2012Sep 26 2012We study the d-wave holographic superconductors (the d-wave model proposed in [arXiv:1003.2991[hep-th]]) immersed in constant external magnetic fields by using the analytic matching method and numerical computation. In the probe limit, we calculate the ... More
