Kinetically induced order from mobility-constrained excitations
Aprem P. Joy, Urban F. P. Seifert
A fascinating feature of strongly correlated systems is that excitations may carry nontrivial quantum numbers under emergent symmetries which, in some cases, may strongly constrain…

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…
