Shannon Entropy and Diffusion Coefficient in Parity-Time Symmetric Quantum Walks
Non-Hermitian topological edge states have many intriguing properties, however, to date, they have mainly been discussed in terms of bulk–boundary correspondence. Here, we propose using a bulk property of diffusion coefficients for probing the topological states and exploring their dynamics. The dif...
