We investigate the origin of exoticity in Fe-based systems via studying the fermiology of ${\mathrm{CaFe}}_{2}{\mathrm{As}}_{2}$ employing angle-resolved photoemission spectroscopy. While the Fermi surfaces (FSs) at 200 K and 31 K are observed to exhibit two-dimensional and three-dimensional (3D) to...
