Evidence for a spinon Fermi surface in the triangular S=1 quantum spin liquid BaNiSbO
B. Fak, S. Bieri, E. Canevet +7
Inelastic neutron scattering is used to study the low-energy magnetic excitations in the spin-1 triangular lattice of the 6H-B phase of BaNiSbO. We study two powder sam…
Antiferro-quadrupolar correlations in the quantum spin ice candidate Pr2Zr2O7
S. Petit, E. Lhotel, S. Guitteny O. Florea +9
We present an experimental study of the quantum spin ice candidate pyrochlore coumpound \przr\ by means of magnetization measurements, specific heat and neutron scattering up to 12…
Field driven magnetostructural transitions in GeCoO
X. Fabrèges, E. Ressouche, F. Duc +9
In the spinel compound GeCoO, the Co pyrochlore sublattice presents remarkable magnetic field-induced behaviors that we unveil through neutron and X-ray single-cryst…
Magnetic properties of the honeycomb oxide NaCoTeO
E. Lefrançois, M. Songvilay, J. Robert +8
We have studied the magnetic properties of NaCoTeO, which features a honeycomb lattice of magnetic Co ions, through macroscopic characterization and neutron diff…
Anatomy of quantum critical wave functions in dissipative impurity problems
Zach Blunden-Codd, Soumya Bera, Benedikt Bruognolo +5
Quantum phase transitions reflect singular changes taking place in a many-body ground state, however, computing and analyzing large-scale critical wave functions constitutes a form…
Fate of spinons at the Mott point
Tsung-Han Lee, Serge Florens, Vladimir Dobrosavljevic
Gapless spin liquids have recently been observed in several frustrated Mott insulators, with elementary spin excitations - "spinons" - reminiscent of degenerate Fermi systems. Howe…
