Spectral damping without quasiparticle decay: The dynamic structure factor of two-dimensional quantum Heisenberg antiferromagnets
Matthew C. O'Brien, Oleg P. Sushkov
Two-dimensional Heisenberg antiferromagnets play a central role in quantum magnetism, yet the nature of dynamic correlations in these systems at finite temperature has remained poo…

Colossal quasiparticle radiation in the Lifshitz spin liquid phase of a two-dimensional quantum antiferromagnet
Matthew C. O'Brien, Oleg P. Sushkov
Strong quantum fluctuations in magnetic systems can create disordered quantum spin liquid phases of matter which are not predicted by classical physics. The complexity of the exoti…

Anomalous thermal broadening from an infrared catastrophe in two-dimensional quantum antiferromagnets
Matthew C. O'Brien, Oleg P. Sushkov
The nature of quasiparticles in 2D quantum antiferromagnets at finite temperature remains an open question despite decades of theoretical work. In particular, it is not fully under…
