Field theory of symmetry-protected valence bond solid states in (2+1) dimensions
Shintaro Takayoshi, Pierre Pujol, Akihiro Tanaka
This paper describes a semiclassical field-theory approach to the topological properties of spatially featureless Affleck-Kennedy-Lieb-Tasaki type valence bond solid ground states…
A short guide to topological terms in the effective theories of condensed matter
Akihiro Tanaka, Shintaro Takayoshi
This article is meant as a gentle introduction to the "topological terms" that often play a decisive role in effective theories describing topological quantum effects in condensed…
Emergent gauge fields and their nonperturbative effects in correlated electrons
Ki-Seok Kim, Akihiro Tanaka
The history of modern condensed matter physics may be regarded as the competition and reconciliation between Stoner's and Anderson's physical pictures, where the former is based on…
Symmetry-protected topological order in magnetization plateau states of quantum spin chains
Shintaro Takayoshi, Keisuke Totsuka, Akihiro Tanaka
A symmetry-protected topologically ordered phase is a short-range entangled state, for which some imposed symmetry prohibits the adiabatic deformation into a trivial state which la…
Spin Berry phase in anisotropic topological insulators
Ken-Ichiro Imura, Yositake Takane, Akihiro Tanaka
Three-dimensional topological insulators are characterized by the presence of protected gapless spin helical surface states. In realistic samples these surface states are extended…
Weak topological insulator with protected gapless helical states
Ken-Ichiro Imura, Yositake Takane, Akihiro Tanaka
A workable model for describing dislocation lines introduced into a three-dimensional topological insulator is proposed. We show how fragile surface Dirac cones of a weak topologic…
