In fact, as early as the 1960s, Koehler et al. (1962), Turch´anyi, G. et al. (1973), Whitworth (1975) found that edge dislocations in centrosymmetric materials, such as sodium chloride, carry charge. Later, Perenko &amp; Whitworth (1983) extended the observation to another kind of centrosymmetric material, ice.…</p><p><a href="https://hackerpaper.kaipfister.de/p/2212.00323/">Paper and discussion history</a>.
