THEORETICAL STUDY ON CORRELATION EFFECTS IN TOP...

This thesis elucidates electron correlation effects in topological matter whose electronic
states hold nontrivial topological properties robust against small perturbations. In addition
to a comprehensive introduction to topological matter  this thesis provides a new perspective
on correlated topological matter.The book comprises three subjects  in which electron
correlations in different forms are considered. The first focuses on Coulomb interactions for
massless Dirac fermions. Using a perturbative approach  the author reveals emergent Lorentz
invariance in a low-energy limit and discusses how to probe the Lorentz invariance
experimentally. The second subject aims to show a principle for synthesizing topological
insulators with common  light elements. The interplay between the spin-orbit interaction and
electron correlation is considered  and Hund's rule and electron filling are consequently found
to play a key role for a strong spin-orbit interaction important for topological insulators.
The last subject is classification of topological crystalline insulators in the presence of
electron correlation. Unlike non-interacting topological insulators  such two- and
three-dimensional correlated insulators with mirror symmetry are demonstrated to be
characterized  respectively  by the Z4 and Z8 group by using the bosonization technique and a
geometrical consideration.
