Abstract

The honeycomb Mott insulator α−RuCl3 loses its low-temperature magnetic order by pressure. We report clear evidence for a dimerized structure at P>1 GPa and observe the breakdown of the relativistic jeff picture in this regime strongly affecting the electronic properties. A pressure-induced Kitaev quantum spin liquid cannot occur in this broken symmetry state. We shed light on the new phase by broadband infrared spectroscopy of the low-temperature properties of α−RuCl3 and ab initio density functional theory calculations, both under hydrostatic pressure.
