A Are all edge states topological?

  1. Aug 1, 2017 #1
    Hey am new to this forum but I have a question regarding topologically protected states.. Lets suppose we have a 1D gapped system divided two to distinct regions that have different periodicity or different properties and that at the centre, where the two regions 'meet' states appear in the gap. The simplest example where this happens is the SSH model. But i was wondering whether this is generally true. Are these states always topological?
