Pair binding and Hund's rule breaking in high-symmetry fullerenes
R. Rausch, C. Karrasch
Highly-symmetric molecules often exhibit degenerate tight-binding states at the Fermi edge. This typically results in a magnetic ground state if small interactions are introduced i…

Relaxation dynamics of a quantum spin coupled to a topological edge state
Qiyu Liu, Christoph Karrasch, Dante Marvin Kennes +1
A classical impurity spin coupled to the spinful Su-Schrieffer-Heeger (SSH) chain is known to exhibit complex switching dynamics with incomplete spin relaxation. Here, we study the…
