Fig. 6: Local valley Hall marker for uniaxial strain.
From: Quantized valley Hall response from local bulk density variations
Spatial dependence of the kernel \({\mathfrak{S}}(x)\) for the same parameters as in Fig. 3 (ατ = 3.255 × 10−4) for a strained sample (solid lines) and for a lattice with a homogeneous external magnetic field \(B={B}_{\tau }^{K}\) (dashed lines). Green and blue colors correspond to chemical potentials μ1 = 0.02 t (first gap) and μ2 = 0.068 t (second gap), respectively.
