 Dear Experts,I need your help visualizing the spin texture.I want to plot spin texture in kx-ky plane after solving Rashba Hamiltonian as provided in the attached file. Kindly help. consider m= hbar = 1, alpha= 0.2 Range of kx and ky = [-1.5,1.5] or [-3,3] Clear[k, m, \[Alpha], \[HBar], \[Sigma]0, \[Sigma]x, \[Sigma]y, \ \[Sigma]z] (*Define symbolic variables*) \[HBar] = \[HBar]; (*The reduced Planck constant*) k = Sqrt[kx^2 + ky^2]; (*Magnitude of the wavevector*) m = m; (*Effective mass of electrons*) \[Alpha] = \[Alpha] ; (*Rashba spin-orbit coupling strength*) (*Define Pauli matrices*) \[Sigma]0 = PauliMatrix[0]; \[Sigma]x = PauliMatrix[1]; \[Sigma]y = PauliMatrix[2]; \[Sigma]z = PauliMatrix[3]; (*Define the Rashba Hamiltonian*) hamiltonian = (\[HBar]^2 k^2)/(2 m) \[Sigma]0 + \[Alpha] (\[Sigma]x \ ky - \[Sigma]y kx); (*Diagonalize the Hamiltonian*) {eigenvalues, eigenvectors} = Eigensystem[hamiltonian];
