      "value": "We consider the emergence of a non-Fermi liquid fixed point in a two-dimensional metal, at the onset of a quantum phase transition from a Fermi liquid state to an incommensurate charge density wave (CDW) ordered phase. The momentum of the CDW boson is centred at the wavevector <math><mi>Q</mi></math>, which connects a single pair of antipodal points on the Fermi surface with antiparallel tangent vectors. We employ the dimensional regularization technique in which the co-dimension of the Fermi surface is extended to a generic value, while keeping the dimension of the Fermi surface itself fixed at one. Although the system is strongly coupled at dimension <math><mi>d</mi><mo>=</mo><mn>2</mn></math>, the interactions become marginal at the upper critical dimension <math><mi>d</mi><mo>=</mo><msub><mrow><mi>d</mi></mrow><mrow><mi>c</mi></mrow></msub></math>, whose value is found to be 5/2. Using a controlled perturbative expansion in the parameter <math><mi>\u03f5</mi><mo>=</mo><msub><mrow><mi>d</mi></mrow><mrow><mi>c</mi></mrow></msub><mo>\u2212</mo><mi>d</mi></math>, we compute the critical exponents of the stable infrared fixed point characterizing the quantum critical point. The scalings of the original theory are determined by setting <math><mi>\u03f5</mi><mo>=</mo><mn>1</mn><mo>/</mo><mn>2</mn></math>, where the fermion self-energy is seen to scale with the frequency with a fractional power law of 2/3, which is the telltale signature of a typical non-Fermi liquid phase."
