Dipolar spin ice regime proximate to an all-in-all-out Néel ground state in the dipolar-octupolar pyrochlore Ce $_{2}$ Sn $_{2}$ O $_{7}$

D. R. Yahne, B. Placke, R. Schäfer +11

The dipolar-octupolar (DO) pyrochlores, R $_{2}$ M $_{2}$ O $_{7}$ (R = Ce, Sm, Nd), are key players in the search for realizable novel quantum spin liquid (QSL) states as a large parameter s…

Abundance of hard-hexagon crystals in the quantum pyrochlore antiferromagnet

Robin Schäfer, Benedikt Placke, Owen Benton +1

We propose a simple family of valence-bond crystals as potential ground states of the $S = 1/2$ and $S = 1$ Heisenberg antiferromagnet on the pyrochlore lattice. Exponentially numerous…

Symmetry protected exceptional points of interacting fermions

Robin Schäfer, Jan C. Budich, David J. Luitz

Non-hermitian quantum systems can exhibit spectral degeneracies known as exceptional points, where two or more eigenvectors coalesce, leading to a non-diagonalizable Jordan block.…
