Abstract
We study the temperature dependence of Coulomb Blockade peak conductance based on the unilateral coupled four quasi-Majoranas system in trivial phase. This non-local transport system is equivalent to an Andreev bound state (ABS) on the left side of the nanowire and a Majorana bound state (MBS) on the right side. In the low-temperature regime, we discover a coherent double Fu-teleportation (FT), where any independent tunneling process always involve two coherent FTs, and we also obtain a T2 conductance behavior. In the high-temperature regime, using the familiar rate equation method, we find that the conductance is proportional to the reciprocal of the temperature. The non-monotonic temperature-dependent characteristic can be distinguished from the traditional Coulomb block case. Finally, we study the 1e and 2e crossover regimes and find the unique double crossover points, this property can help us implement the detection of our proposed model in the experiment.
