Diffusion and relaxation of topological excitations in layered spin liquids
Aprem P. Joy, Roman Lange, Achim Rosch
Relaxation processes in topological phases such as quantum spin liquids are controlled by the dynamics and interaction of fractionalized excitations. In layered materials hosting t…

Raman spectroscopy of anyons in generic Kitaev spin liquids
Aprem P. Joy, Achim Rosch
Optical probes have emerged as versatile tools for detecting exotic fractionalized phases in quantum materials. We calculate the low-energy Raman response arising from mobile, inte…

Projectively implemented altermagnetism in an exactly solvable quantum spin liquid
Avedis Neehus, Achim Rosch, Johannes Knolle +1
Altermagnets are a new class of symmetry-compensated magnets with large spin splittings. Here, we show that the notion of altermagnetism extends beyond the realm of Landau-type ord…
