Topological Triplon Modes and Bound States in a Shastry-Sutherland Magnet
P. A. McClarty, F. Krüger, T. Guidi +5
The twin discoveries of the quantum Hall effect, in the 1980's, and of topological band insulators, in the 2000's, were landmarks in physics that enriched our view of the electroni…
Bound states and field-polarized Haldane modes in a quantum spin ladder
S. Ward, P. Bouillot, C. Kollath +10
The challenge of one-dimensional systems is to understand their physics beyond the level of known elementary excitations. By high-resolution neutron spectroscopy in a quantum spin…
Finite-temperature scaling of spin correlations in an experimental realization of the one-dimensional Ising quantum critical point
M. Hälg, D. Hüvonen, T. Guidi +5
Inelastic neutron scattering is used to study the finite-temperature scaling behavior of the local dynamic structure factor in the quasi-one-dimensional quantum antiferromagnet NTE…
Two-dimensional magnetic interactions in LaFeAsO
M. Ramazanoglu, 1, 2 J. Lamsal +14
Inelastic neutron scattering measurements demonstrate that the magnetic interactions in antiferromagnetic LaFeAsO are two-dimensional. Spin wave velocities within the Fe layer and…
Emergence of highly degenerate excited states in frustrated magnet MgCrO
K. Tomiyasu, T. Yokobori, Y. Kousaka +5
High degeneracy in ground states leads to the generation of exotic zero-energy modes, a representative example of which is the formation of molecular spin liquid-like fluctuations…
Spin wave measurements over the full Brillouin zone of multiferroic BiFeO3
Jaehong Jeong, E. A. Goremychkin, T. Guidi +9
Using inelastic neutron scattering technique, we measured the spin wave dispersion over the entire Brillouin zone of room temperature multiferroic BiFeO3 single crystals with magne…
