Crystal-Field Symmetry Constraints in Layered Honeycomb ErBr $_{3}$

Biaoyan Hu, Mingyuan Hu, Franz Demmel +3

Crystal-field symmetry restricts the ground-state Kramers doublet of ErBr $_{3}$ to one of two classes. We show that the compressed octahedral environment selects the class with $\lan…

Zeeman split Kramers doublets in spin-supersolid candidate Na $_{2}$ BaCo(PO $_{4}$ ) $_{2}$

T. I. Popescu, N. Gora, F. Demmel +6

Na $_{2}$ BaCo(PO $_{4}$ ) $_{2}$ is a triangular antiferromagnet that displays highly efficient adiabatic demagnetization cooling (J. Xiang $et al.$ Nature $625$ , 270 (…

Non-linear soliton confinement in weakly coupled antiferromagnetic spin chains

H. Lane, C. Stock, S. -W. Cheong +3

We analyze the low-energy dynamics of quasi one dimensional, large- $S$ quantum antiferromagnets with easy-axis anisotropy, using a semi-classical non-linear sigma model. The saddle…

Spinon Confinement and a Sharp Longitudinal Mode in Yb $_{2}$ Pt $_{2}$ Pb in Magnetic Fields

W. J. Gannon, I. A. Zaliznyak, L. S. Wu +7

The fundamental excitations in an antiferromagnetic chain of spins-1/2 are spinons, de-confined fractional quasiparticles that when combined in pairs, form a triplet excitation con…

From Ising resonant fluctuations to static uniaxial order in antiferromagnetic and weakly superconducting CeCo(In $_{1 - x}$ Hg $_{x}$ ) $_{5}$ ( $x$ =0.01)

C. Stock, J. A. Rodriguez-Rivera, K. Schmalzl +5

CeCo(In $_{0.990}$ Hg $_{0.010}$ ) $_{5}$ is a charge doped variant of the $d$ -wave CoCoIn $_{5}$ superconductor with coexistent antiferromagnetic and superconducting transitions occurri…

Orphan spins and bound in-gap states in the $S = \frac{5}{2}$ antiferromagnet CaFe $_{2}$ O $_{4}$

C. Stock, E. E. Rodriguez, N. Lee +11

CaFe $_{2}$ O $_{4}$ is an anisotropic $S = \frac{5}{2}$ antiferromagnet with two competing $A$ ( $↑↑↓↓$ ) and $B$ ($\uparrow \downarrow \uparrow \downar…
