We examine different topological phases in three-dimensional non-centrosymmetric superconductors with time-reversal symmetry by using three different types of topological invariants. Due to the bulk b...

We consider the dimensional crossover in the topological matter, which involves the ransformation of different types of topologically protected zeroes in the fermionic spectrum. In the considered case...
