Observation of Fractional Disclination Charges Induced by Gain and Loss

Fractional charge, a hallmark of modern electric polarization theory, provides a topological framework for understanding quantized polarization. It has only recently been recognized that real-space topological defects, such as disclinations, can further modify charge fractionalization, as an interpl...
