Directional Ballistic Transport in Quantum Waveguides
Adam Black, David Damanik, Peter Kuchment +2
We study the transport properties of Schrödinger operators on with potentials that are periodic in some directions and compactly supported in the others. Such syste…

Directional Ballistic Transport for Partially Periodic Schrödinger Operators on
Adam Black, David Damanik, Tal Malinovitch +1
We study the transport properties of Schrödinger operators on with potentials that are periodic in one direction and compactly supported in the other. Such systems…

Spectral Multiplicity Bounds for Jacobi Operators on Star-Like Graphs
Netanel Levi, Tal Malinovitch
We study the spectral multiplicity of Jacobi operators on star-like graphs with branches. Recently, it was established that the multiplicity of the singular continuous spectrum…
