## Description

- description: While Landau’s Fermi liquid theory provides the standard description
    for two- and three-dimensional (2D/3D) conductors, the physics of interacting
    one-dimensional (1D) conductors is governed by the distinct Luttinger liquid (LL)
    theory1,2. Can a LL-like state, in which low energy excitations are fractionalized
    electronic modes, emerge in a 2D system as a stable zero temperature ground phase?
    This long-standing question, first brought up by Anderson3–6 three decades ago,
    is crucial in the study of non-Fermi liquids7–11 but remains unsettled. A recent
    experiment12 identified a moiré superlattice of twisted bilayer tungsten ditelluride
    (tWTe2) with a small interlayer twist angle as a 2D host of the LL physics at
    temperatures of a few kelvins. In this work, we report experimental evidence for
    an anisotropic 2D LL state, down to at least 50 mK, spontaneously formed in a
    tWTe2 system with a twist angle of ~ 3o. While the system is metallic and nearly
    isotropic above 2 K, a dramatically enhanced electronic anisotropy develops in
    the millikelvin regime, featuring qualitatively distinct transport along two orthogonal
    in-plane directions. In the strongly anisotropic regime, we observe transport
    characteristics of a LL state, i.e., the universal power law scaling behaviors
    in conductance as a function of both temperature and voltage bias. Our results
    represent a major step forward in the search for stable LL physics beyond 1D,
    opening a new avenue for studying non-Fermi liquids and unconventional quantum
    matter.
