Edge Modes of Zn Symmetric Chains
Stockholm University, Faculty of Science, Department of Physics.
2017 (English)Licentiate thesis, comprehensive summary (Other academic)
Abstract [en]

In this Licentiate Thesis we will study the topological phases of Z2 and Z3 symmetric chains.

We will present the Kitaev chain, a Z2 symmetric model of spinless fermions, and obtain all

the eigenstates of the model with an open boundary condition which hosts Majorana zero

modes in the topological phase. We will also present zero modes of the Kitaev chain with

phase gradient in the pairing term and longer range couplings. This model could host

Majorana zero modes as well as a 'one-sided' zero energy fermionic state. We will study the

role of interactions on the topological phase by considering a special model for which one can

obtain the ground states exactly. Similarly, for the Z3 case, we will present a 3-state clock

model as well as a solvable model for which the ground states are obtained exactly. We will

briefly address the presence of edge modes in these models as well.
