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…
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…
Spin fluctuations and superconductivity in layered -electron superlattices
Yasuhiro Tada, Robert Peters
We investigate magnetic and superconducting properties of layered -electron superlattices within the fluctuation exchange approximation (FLEX). We show that spin fluctuations, w…
Large and Small Fermi-Surface Spin Density Waves in the Kondo Lattice Model
Robert Peters, Norio Kawakami
We demonstrate the existence of metallic spin density waves (SDWs) in the Kondo lattice model on a square lattice for a wide range of parameters by means of real space dynamical me…
Local origin of the pseudogap in the attractive Hubbard model
Robert Peters, Johannes Bauer
We provide a new perspective on the pseudogap physics for attractive fermions as described by the three-dimensional Hubbard model. The pseudogap in the single-particle spectral fun…
