Jahn-Teller effect in Mott insulators: Ground states and thermal fluctuations
Kathleen Hart, Ruairidh Sutcliffe, Arun Paramekanti
The interplay of strong atomic spin-orbit coupling with Jahn-Teller (JT) lattice distortions is an important theme in quantum materials hosting heavy atoms. A prototypical example…

Modified large- approach to gapless spin liquids, magnetic orders, and dynamics: Application to triangular lattice antiferromagnets
Anjishnu Bose, Kathleen Hart, Ruairidh Sutcliffe +1
Recent work has shown that the triangular lattice spin- - Heisenberg and XXZ antiferromagnets may exhibit coplanar or supersolid orders proximate to a gapless Dirac…

spin-phonon simulations of Floquet dynamics in spin Mott insulators
Ruairidh Sutcliffe, Kathleen Hart, Gil Refael +1
The dynamics of magnetic moments coupled to phonons is of great interest for understanding spin transport in solids as well as for our ability to control magnetism via tailored pho…
