Scattering from isospectral quantum graphs
Ram Band, Adam Sawicki, Uzy Smilansky
Quantum graphs can be extended to scattering systems when they are connected by leads to infinity. It is shown that for certain extensions, the scattering matrices of isospectral g…

Symplectic geometry of entanglement
Adam Sawicki, Alan Huckleberry, Marek Kuś
We present a description of entanglement in composite quantum systems in terms of symplectic geometry. We provide a symplectic characterization of sets of equally entangled states…
