Duality and domain wall dynamics in a twisted Kitaev chain
C. M. Morris, Nisheeta Desai, J. Viirok +9
The Ising chain in transverse field is a paradigmatic model for a host of physical phenomena, including spontaneous symmetry breaking, topological defects, quantum criticality, and…
Magnetic Excitations and Continuum of a Field-Induced Quantum Spin Liquid in -RuCl
Zhe Wang, S. Reschke, D. Hüvonen +6
We report on terahertz spectroscopy of quantum spin dynamics in -RuCl, a system proximate to the Kitaev honeycomb model, as a function of temperature and magnetic field. An…
Finite-temperature scaling of spin correlations in a partially magnetized Heisenberg chain
M. Hälg, D. Hüvonen, N. P. Butch +2
Inelastic neutron scattering is employed to study transverse spin correlations of a Heisenberg chain compound in a magnetic field of 7.5 T. The target compound is the antif…
Spin dynamics in pressure-induced magnetically-ordered phases in PHCC
G. Perren, J. S. Möller, D. Hüvonen +2
We present inelastic neutron scattering experiments on the frustrated gapped quantum magnet piperazinium hexachlorodicuprate under applied hydrostatic pressure. These resul…
Dynamics of a bond-disordered quantum magnet near criticality
K. Yu. Povarov, E. Wulf, D. Hüvonen +3
Neutron scattering is used to study NiClBr4SC(NH), , a bond-disordered modification of the well-known gapped antiferromagnetic quantum sp…
Critical exponents and intrinsic broadening of the field-induced transition in NiCl4SC(NH)
E. Wulf, D. Hüvonen, R. Schönemann +7
The field-induced ordering transition in the quantum spin system NiCl4SC(NH) is studied by means of neutron diffraction, AC magnetometry and relaxation calorimet…
