Fragile aspects of topological transition in lossy and parity-time symmetric quantum walks
Quantum walks often provide telling insights about the structure of the system on which they are performed. In [Formula: see text] -symmetric and lossy dimer lattices, the topological properties of the band structure manifest themselves in the quantization of the mean displacement of such a walker....
