Spread complexity and localization in $\mathcal{P}\mathcal{T}$-symmetric systems

Aranya Bhattacharya, Rathindra Nath Das, Bidyut Dey +1

We present a framework for investigating wave function spreading in $\mathcal{P}\mathcal{T}$-symmetric quantum systems using spread complexity and spread entropy. We consider a tight-binding…
