Magnetic and dielectric order in the kagomelike francisite Cu3Bi(SeO3)(2)O2Cl

We report a single-crystal neutron diffraction and inelastic neutron scattering study on the spin 1/2 cuprate Cu3Bi(SeO3)(2)O2Cl, complemented by dielectric and electric polarization measurements. The study clarifies a number of open issues concerning this ...

Anomalous spin dynamics in the coupled spin tetramer system CuSeO3

Helmuth Berger

We report high-field magnetization, high-frequency electron spin resonance (ESR), and Se-77 nuclear magnetic resonance (NMR) measurements on the linear spin tetramer system CuSeO3, consisting of strongly interacting Cu(1) dimers and weakly coupled Cu(2) sp ...

Coherent generation of symmetry-forbidden phonons by light-induced electron-phonon interactions in magnetite

Oleg Yazyev, Fabrizio Carbone, Frank van Mourik, Christopher Alexander Arrell, Edoardo Baldini, Andreas Helmut Christian Mann, Simone Borroni

Symmetry breaking across phase transitions often causes changes in selection rules and emergence of optical modes which can be detected via spectroscopic techniques or generated coherently in pump-probe experiments. In second-order or weakly first-order tr ...

Spiral spin-liquid and the emergence of a vortex-like state in MnSc2S4

Jonathan White, Gregory Scott Tucker, Romain Sibille, Shang Gao

Spirals and helices are common motifs of long-range order in magnetic solids, and they may also be organized into more complex emergent structures such as magnetic skyrmions and vortices. A new type of spiral state, the spiral spin-liquid, in which spins f ...

Clocking the onset of bilayer coherence in a high- Tc cuprate

Fabrizio Carbone, Frank van Mourik, Christopher Alexander Arrell, Edoardo Baldini, Andreas Helmut Christian Mann, Dragan Mihailovic

In cuprates, a precursor state of superconductivity is speculated to exist above the critical temperature TC. Here we show via a combination of far-infrared ellipsometry and ultrafast broadband optical spectroscopy that signatures of such a state can be ob ...

Multi-triplet bound states and finite-temperature dynamics in highly frustrated quantum spin ladders

Frédéric Mila, Bruce Normand

Low-dimensional quantum magnets at finite temperatures present a complex interplay of quantum and thermal fluctuation effects in a restricted phase space. While some information about dynamical response functions is available from theoretical studies of th ...

Spontaneous dimerization, critical lines, and short-range correlations in a frustrated spin-1 chain

Frédéric Mila, Natalia Chepiga

We report on a detailed investigation of the spin-1 J1−J2−J3 Heisenberg model, a frustrated model with nearest-neighbor coupling J1, next-nearest neighbor coupling J2, and a three-site interaction J3[(Si−1⋅Si)(Si⋅Si+1)+H.c.] previously studied in [Phys. Re ...
