Topological band structure of excitons in octochlore KTbF: an analog of the Luttinger Semimetal
Olivier Demortier, Françoise Damay, Paul McClarty +3
Understanding the symmetry and topology of band structures in crystalline solids has been among the defining themes of a generation of condensed matter physicists, with implication…
Mesoscopic tunneling in strontium titanate
Benoît Fauqué, Philippe Bourges, Alaska Subedi +6
Spatial correlation between atoms can generate a depletion in the energy dispersion of acoustic phonons. Two well known examples are rotons in superfluid helium and the Kohn anomal…
Manifolds of magnetic ordered states and excitations in the almost Heisenberg pyrochlore antiferromagnet MgCr2O4
S. Gao, K. Guratinder, V. Tsurkan +18
In spinels ACr2O4 (A=Mg, Zn) realisation of the classical pyrochlore Heisenberg antiferromagnet model is complicated by a strong spin-lattice coupling: the extensive degeneracy of…
Elastic softness of hybrid lead halide perovskites
A. C. Ferreira, A. Létoublon, S. Paofai +10
Much recent attention has been devoted towards unravelling the microscopic optoelectronic properties of hybrid organic-inorganic perovskites (HOP). Here we investigate by coherent…
Longitudinal and Transverse Zeeman Ladders in the Ising-Like Chain Antiferromagnet BaCo2V2O8
B. Grenier, S. Petit, V. Simonet +6
We explore the spin dynamics emerging from the Néel phase of the chain compound antiferromagnet BaCo2V2O8. Our inelastic neutron scattering study reveals unconventional discrete sp…
