WebJan 29, 2015 · We revisit the problem of electrons on a square lattice below half filling close to an Ising-nematic quantum critical point. For Fermi surfaces with sufficiently strong antinodal nesting, the static nematic susceptibility is maximal at the antinodal nesting wave vector within a simple RPA calculation. We present a detailed analysis of the nematic … WebFermi surface nesting is revealed as a strong candidate for driving charge-density wave formation in these compounds. The nesting vector obtained from positron annihilation experiments on GdTe3 is determined to be q=s0.28±0.02 ,0,0da* sa*=2p/ad, in excellent agreement with previous experimental and theoretical studies. WebSep 1, 2024 · Notably, the wave vector q 3 shows a small mis-angle of ∼ 11° to the (1 × 1) wave vector (green dashed line), suggesting the existing of a hidden incommensurate CDW phase with period of ∼ 2a. Thus, the interference between the ( ) and the incommensurate ∼ 2 a CDW phases in fact results in the short-range ( ) and ( ) CDW reconstructions in real … cooking a pie shell
