Thermodynamics of Kitaev magnets — •Bahareh Ghannad and Simon Trebst — University Of Cologne

Kitaev spin models are prototypical frustrated magnets that exhibit low-temperature spin liquid physics. This is true independent of whether the constituent spin degrees of freedom are classical O(3) Heisenberg spins or quantum SU(2) spin-1/2 spins. Here, we will discuss thermodynamic signatures of a variety of Kitaev spin models for different lattice geometries and contrast them for the classical and quantum case. Of particular interest are two-spin and four-spin correlation functions that reveal the nature of the spin liquid regime. We report results from both analytical approaches and large-scale numerical Monte Carlo simulations.
