The Effect of Noise on the Dirac Phase of Electron in The Presence of   Screw Dislocation
  The effect of noise on the Dirac phase of electron in the presence of screw dislocation is studied. An uncorrelated noise, which coincides with the nature of thermal fluctuations, is adopted. Results indicate that the Dirac phase is robust against existing noise in the system.
