Signature of Tomonaga-Luttinger Liquid State in Epitaxial CoSb Nanoribbons

ORAL

Abstract

Here, building upon molecular beam epitaxy, we have fabricated CoSb nanoribbons on SrTiO3(001) substrates, and investigated the electronic structures by in situ angle-resolved photoemission spectroscopy. Straight Fermi surface sheets containing multibands are observed to disperse without lateral undulations. The corresponding spectra exhibit power-law scaling with the energy and temperature in the vicinity of Fermi level, serving as a signature of Tomonaga-Luttinger liquid (TLL) state. We also reveal that this TLL system is stable against charge density wave and superconductivity down to low temperature.
