A unified approach to Schrödinger evolution of superoscillations and supershifts
Yakir Aharonov, Jussi Behrndt, Fabrizio Colombo +1
Superoscillating functions and supershifts appear naturally in weak measurements in physics. Their evolution as initial conditions in the time dependent Schrödinger equation is an…

Green's Function for the Schrödinger Equation with a Generalized Point Interaction and Stability of Superoscillations
Yakir Aharonov, Jussi Behrndt, Fabrizio Colombo +1
In this paper we study the time dependent Schrödinger equation with all possible self-adjoint singular interactions located at the origin, which include the and -potentials…
