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…
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…
Phonon-driven multipolar dynamics in a spin-orbit coupled Mott insulator
Kathleen Hart, Ruairidh Sutcliffe, Gil Refael +1
Motivated by advances in pump-probe experiments and light-driven phenomena, we theoretically study the impact of pumped and driven phonons in Mott insulators which host multipole m…
Pseudo-chiral phonon splitting from octupolar magnetic order
Ruairidh Sutcliffe, Kathleen Hart, Swati Chaudhary +1
Motivated by the recent discovery of anomalously large magnetic response of chiral phonons in dipolar magnets, we explore an extension to study Einstein quantum phonon modes couple…
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…
