Abstract: Two-dimensional Wigner distribution (2D WD) and ambiguity function (2D AF) are important tools for time–frequency analysis and signal processing, especially in the analysis of 2D chirp signals. In this paper, based on the classical 2D… read more here.

Abstract: The two-dimensional Wigner crystal (WC) occurs in the strongly interacting regime (r_{s}≫1) of the two-dimensional electron gas (2DEG). The magnetism of a pure WC is determined by tunneling processes that induce multispin ring-exchange interactions, resulting… read more here.
