Sequential topology: iterative topological phase transitions in finite chiral structures
Maxine M. McCarthy, D. M. Whittaker
We present theoretical and experimental results probing the rich topological structure of arbitrarily disordered finite tight binding Hamiltonians with chiral symmetry. We extend t…

Nut digraphs
Nino BaÅ¡iÄ, Patrick W. Fowler, Maxine M. McCarthy +1
A nut graph is a simple graph whose kernel is spanned by a single full vector (i.e. the adjacency matrix has a single zero eigenvalue and all non-zero kernel eigenvectors have no z…
