A report on magnetic monopole from scientists of Stanford and Fudan

Inducing a Magnetic Monopole with Topological Surface States


Existence of the magnetic monopole is compatible with the fundamental laws of nature;
however, this elusive particle has yet to be detected experimentally. We show theoretically that an
electric charge near a topological surface state induces an image magnetic monopole charge due
to the topological magneto-electric effect. The magnetic field generated by the image magnetic
monopole may be experimentally measured, and the inverse square law of the field dependence
can be determined quantitatively. We propose that this effect can be used to experimentally realize
a gas of quantum particles carrying fractional statistics, consisting of the bound states of the
electric charge and the image magnetic monopole charge.
