Field-induced first order transitions and phase coexistence in the Kitaev quantum spin liquid candidate BaCo2(AsO4)2
Tanner J. Legvold, Bin Gao, Rong-Zhu Lin +9
BaCo2(AsO4)2 (BCAO) is an insulating Kitaev quantum spin liquid candidate with a rich low-temperature phase diagram. Below 5 K, it exhibits double-zigzag magnetic order. Upon appli…

Chemical potential of magnon polarons
Violet Williams, Benedetta Flebus
Using a rotationally invariant formulation of spin-lattice coupling, we derive a rigorous definition of the chemical potential for magnon-polaron quasiparticles in collinear ferrom…

Angular Momentum Fluctuations in the Phonon Vacuum of Symmetric Crystals
Rule Yi, Violet Williams, Benedetta Flebus
Although time-reversal and inversion symmetry constrain the angular momentum of each phonon mode to vanish, we show that the vacuum state of crystals with such symmetries can never…
