Crystal structure of the inversion-breaking metal Cd2Re2O7
M. R. Norman
Second harmonic generation (SHG) on the pyrochlore metal Cd2Re2O7 indicates the presence of three order parameters setting in below an inversion breaking transition. Here, we explo…
Evidence for a Parity Broken Monoclinic Ground State in the S = 1/2 Kagomé Antiferromagnet Herbertsmithite
N. J. Laurita, A. Ron, J. W. Han +9
Nearest-neighbor interacting S = 1/2 spins on the ideal Kagomé lattice are predicted to form a variety of novel quantum entangled states, including quantum spin-liquid (SL) and val…
Valence bond phases of herbertsmithite and related copper kagome materials
M. R. Norman, N. J. Laurita, D. Hsieh
Recent evidence from magnetic torque, electron spin resonance, and second harmonic generation indicate that the prototypical quantum spin liquid candidate, herbertsmithite, has a s…
Similarities and differences between infinite-layer nickelates and cuprates and implications for superconductivity
Antia S. Botana, Michael R. Norman
We have revisited the electronic structure of infinite-layer RNiO (R= La, Nd) in light of the recent discovery of superconductivity in Sr-doped NdNiO. From a comparison to…
Néel and stripe ordering from spin-orbital entanglement in -SrCrO
Z. H. Zhu, W. Hu, C. A. Occhialini +6
The rich phenomenology engendered by the coupling between the spin and orbital degrees of freedom has become appreciated as a key feature of many strongly-correlated electron syste…
Quantum Spin Liquids
C. Broholm, R. J. Cava, S. A. Kivelson +3
Spin liquids are quantum phases of matter that exhibit a variety of novel features associated with their topological character. These include various forms of fractionalization - e…
