Coexistence of light and heavy surface states in a topological multi-band Kondo insulator
Robert Peters, Tsuneya Yoshida, Hirofumi Sakakibara +1
We analyze the impact of strong correlations on the surface states of a three-dimensional topological Kondo insulator. An important observation is that correlations are strongly in…
Bosonic symmetry protected topological phases with reflection symmetry
Tsuneya Yoshida, Takahiro Morimoto, Akira Furusaki
We study two-dimensional bosonic symmetry protected topological (SPT) phases which are protected by reflection symmetry and local symmetry [, , U(1)$\rti…
Restoration of topological properties at finite temperatures in a heavy-fermion system
Tsuneya Yoshida, Robert Peters, Norio Kawakami
We study how topological phases evolve in the Kane-Mele-Kondo lattice at finite temperatures and obtain the topological Doniach phase diagram. In particular, we find an intriguing…
Correlation effects on topological crystalline insulators
Tsuneya Yoshida, Akira Furusaki
We study interaction effects on the topological crystalline insulators protected by time-reversal () and reflection symmetry () in two and three spatial dimensions. From the…
