Deriving the Kijowski Arrival-Time POVM from the Schrödinger Current: Minimal Positivity and Uniqueness
Avi Marchewka
Quantum backflow refers here to the appearance of a negative Schrödinger current for a state whose momentum support is entirely positive. We ask for the smallest modification of th…
The MS Unidirectional Current as a Generalization of the ABC Absorption Current
Avi Marchewka
For a free scalar particle in one spatial dimension, in a single-pass half-line geometry, we compare the absorbing Robin boundary condition with the generalized Marchewka--Schuss (…
The Unidirectional Current as First Arrival-Time POVM: An MS-Kijowski Identity, Physical Interpretation, and Mathematical Applications
Avi Marchewka
Detector-based first-arrival models and operator-based arrival-time observables provide two conceptually distinct approaches to the quantum time-of-arrival problem. Here we connect…
A direct test for instantaneous collapse of wave functions in configuration space
Avi Marchewka
Wavefunction collapse is a puzzling aspect of quantum mechanics. Designing a test to confirm the instantaneousness of collapse has turned out to be challenging, especially for coll…
Full Realization Scheme of the Tensor Product Space of N Distinguishable Photons in Two States
Avi Marchewka
The ability to control and hence to realize a given number of photons is of major interest from a fundamental point of view, e.g. Bell inequalities, photons bunching. In recent yea…
A bunching parameter interferometer: Generalization of HOM effect
Avi Marchewka
Are photons either bunched or unbunched, or are these particular cases of a wider phenomenon? Here we will show that bunched and unbunched photons are indeed two extreme cases of a…
