Quasi-flat plasmonic bands in twisted bilayer graphene
T. Stauber, H. Kohler
The charge susceptibility of twisted bilayer graphene is investigated in the Dirac cone, respectively random-phase approximation. For small enough twist angles …

Non-equilibrium dynamics of a system with Quantum Frustration
Heiner Kohler, Andreas Hackl, Stefan Kehrein
Using flow equations, equilibrium and non-equilibrium dynamics of a two-level system are investigated, which couples via non-commuting components to two independent oscillator bath…

Quantum frustration of dissipation by a spin bath
D. D. Bhaktavatsala Rao, Heiner Kohler, Fernando Sols
We investigate the evolution of a central spin coupled to a spin bath without internal dynamics. We compare the cases where the bath couples to one or two components of the spin. I…
