Fractional corner charge of sodium chloride
WebHere, we put on the table a proposal of the three-dimensional octupole insulator with fractionally quantized corner charges +/-e/8: sodium chloride, commonly known as table salt. We further show that the electrostatic signature of the fractional charge is well-preserved even when the ideal crystal is sprinkled with defects.
