Tomography of many-body weak values: Mach-Zehnder interferometry
arXiv:0805.2737 · doi:10.1103/PhysRevLett.101.226802
Abstract
We propose and study a weak value (WV) protocol in the context of a solid state setup, specifically, an electronic Mach-Zehnder interferometer. This is the first specific proposal to measure both the real and imaginary part (i.e., complete tomography) of a WV. We also analyze the manifestation of many-body physics in the WV to be measured, including finite temperature and shot-noise-like contributions.
