Abstract:While the vast majority of known physical realizations of the Tomonaga-Luttinger liquid (TLL) have repulsive interactions defined with the dimensionless interaction parameter Kc < 1, we here report that Rb2Mo3As3 is in the opposite TLL regime of attractive interactions. This is concluded from a TLL-characteristic power-law temperature dependence of the 87 Rb spin-lattice relaxation rates over broad temperature range yielding the TLL interaction parameter for charge collective modes Kc = 1.4. The TLL of the one… Show more
