Two-Peak Heat Capacity Accounts for $R ln (2)$ Entropy and Ground State Access in the Dipole-Octupole Pyrochlore Ce $_{2}$ Hf $_{2}$ O $_{7}$

E. M. Smith, A. Fitterman, R. Schäfer +18

Magnetic heat capacity measurements of a high-quality single crystal of the dipole-octupole pyrochlore Ce $_{2}$ Hf $_{2}$ O $_{7}$ down to a temperature of $T = 0.02$ K are reported. These s…

Ising Fracton Spin Liquid on the Honeycomb Lattice

Benedikt Placke, Owen Benton, Roderich Moessner

We study a classical Ising model on the honeycomb lattice with local two-body interactions and present strong evidence that at low temperature it realizes a higher-rank Coulomb liq…

Quantum Spin Ice Response to a Magnetic Field in the Dipole-Octupole Pyrochlore Ce $_{2}$ Zr $_{2}$ O $_{7}$

E. M. Smith, J. Dudemaine, B. Placke +17

We report new heat capacity measurements on single crystal Ce $_{2}$ Zr $_{2}$ O $_{7}$ down to $\sim$ 0.1 K in a magnetic field along the $[1, 1 ˉ, 0]$ direction. These new measurements s…

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…

Reply to "Comment on: 'Case for a U(1) $_{π}$ Quantum Spin Liquid Ground State in the Dipole-Octupole Pyrochlore $Ce_{2} Zr_{2} O_{7}$ ' "

E. M. Smith, O. Benton, D. R. Yahne +20

In his comment [arXiv:2209.03235], S. W. Lovesey argues that our analysis of neutron scattering experiments performed on Ce $_{2}$ Zr $_{2}$ O $_{7}$ is invalid. Lovesey argues that we have n…

The case for a U(1) $_{π}$ Quantum Spin Liquid Ground State in the Dipole-Octupole Pyrochlore Ce $_{2}$ Zr $_{2}$ O $_{7}$

E. M. Smith, O. Benton, D. R. Yahne +20

The Ce $^{3 +}$ pseudospin- $\frac{1}{2}$ degrees of freedom in the pyrochlore magnet Ce $_{2}$ Zr $_{2}$ O $_{7}$ are known to possess dipole-octupole (DO) character, making it a candidate for…

Hierarchy of energy scales and field-tunable order by disorder in dipolar-octupolar pyrochlores

Benedikt Placke, Roderich Moessner, Owen Benton

Dipolar-octupolar pyrochlore magnets in a strong external magnet field applied in the [110] direction are known to form a `chain' state, with subextensive degeneracy. Magnetic mome…
