Abstract

Aspects of Majorana Bound States in One-Dimensional Systems with and without Time-Reversal Symmetry

In this thesis we study Majorana bound states in one dimension both in the time-reversal symmetric and in the case of broken time-reversal symmetry. These bound states are interesting because they provide evidence of topological phases and may potentially be used for topological quantum computation. For the time-reversal-symmetric case we study its applicability to topological quantum computation and the effect interactions can have on the time-reversal-symmetric phase hosting Majorana bound states. For the case with broken time-reversal symmetry we study the influence of electric environments an probing them via a tunnel probe.
