A pointlike electric charge close to the surface of a three dimensional topological insulator induces a magnetic monopole mirror charge. We study the distance dependence of the statistical angle describing this induced dyon system. We find that the total angular momentum, which sometimes is used as signature of the statistical angle, for an electron outside a finite size spherical or tube shaped topological insulator is zero for any finite distance between the electron and the surface. However…

TLDR
The thermodynamics of the system is studied, finding a symmetry preserving compressible state at low temperatures, whose excitations exhibit hyperscaling violation, consistent with the expectation of gapless fermionic excitations forming a Fermi surface at finite density.
