Non-Hermitian scattering on a tight-binding lattice
Phillip C. Burke, Jan Wiersig, Masudul Haque
We analyze the scattering dynamics and spectrum of a quantum particle on a tight-binding lattice subject to a non-Hermitian (purely imaginary) local potential. The reflection, tran…

Nonorthogonality constraints in open quantum and wave systems
Jan Wiersig
It is known that the overlap of two energy eigenstates in a decaying quantum system is bounded from above by a function of the energy detuning and the individual decay rates. This…
