Trivial phase in Kitaev chain, trivial phase in what sense?

I am reading 1D p-wave SC proposed by Kiteav---Kitaev chain recently. This paramedic model somehow bothers me with the word "trivial." In this SE post, the answer pointed out what we mean by "...

Are there topological non-trivial states in zero dimension?

The periodic table of topological insulators and superconductors suggests that there can be topological non-trivial phases in zero dimension in non-interacting system with certain symmetries. A 0D ...

Vortices and chemical potential in topological superconductors

I am trying to read up some review articles about Majorana physics in topological material, but I am not really familiar with the condensed matter terminology (with condensed matter in general I ...
