Spectra and transport of probability and energy densities in a $\mathcal{P}\mathcal{T}$-symmetric square well with a delta-function potential

Francisco Ricardo Torres Arvizu, Adrian Ortega, Hernán Larralde

We study the spectrum, eigenstates and transport properties of a simple $\mathcal{P}\mathcal{T}$-symmetric model consisting in a finite, complex, square well potential with a delta…
