Order-by-disorder in magnets with frustrated spin interactions -- classical and large- limits via the spin functional integral
Peng Rao, Johannes Knolle
We investigate spin systems with extensive degeneracies in the classical ground states due to anisotropic frustrated spin interactions, where the degeneracy is not protected by sym…

Van-Hove singularities and competing instabilities in an altermagnetic metal
Peng Rao, Johannes Knolle, Laura Classen
Van-Hove (VH) singularities in the single-particle band spectrum are important for interaction-driven quantum phases. Whereas VH points are usually spin-degenerate, in newly propos…

Dynamical response theory of interacting Majorana fermions and its application to generic Kitaev quantum spin liquids in a field
Peng Rao, Roderich Moessner, Johannes Knolle
Motivated by the appearance of Majorana fermions in a broad range of correlated and topological electronic systems, we develop a general method to compute the dynamical response of…
