Abstract
|
Motivated by recent developments in the field of topological superconductors, we show that there is a topological phase transition (TPT) for three dimensional Dirac superconductors (3DDS) in the presence of pseudoscalar superconducting order parameter which leads to the appearance of a two dimensional Majorana sea (2DMS) on its surface. The perfect Andreev–Klein transmission, resonant peak with robust character in the differential conductance and 4π periodic Josephson current are .experimental signatures of 2DMS
