Field stability of Majorana spin liquids in antiferromagnetic Kitaev models
Christoph Berke, Simon Trebst, Ciarán Hickey
Magnetic fields can give rise to a plethora of phenomena in Kitaev spin systems, such as the formation of non-trivial spin liquids in two and three spatial dimensions. For the orig…
Field-Driven Gapless Spin Liquid in the Spin-1 Kitaev Honeycomb Model
Ciarán Hickey, Christoph Berke, Panagiotis Peter Stavropoulos +2
Recent proposals for spin-1 Kitaev materials, such as honeycomb Ni oxides with heavy elements of Bi and Sb, have shown that these compounds naturally give rise to antiferromagnetic…
High-Field Quantum Disordered State in -RuCl3: Spin Flips, Bound States, and a Multi-Particle Continuum
A. Sahasrabudhe, D. A. S. Kaib, S. Reschke +15
Layered -RuCl3 has been discussed as a proximate Kitaev spin liquid compound. Raman and THz spectroscopy of magnetic excitations confirm that the low-temperature antiferromagnet…
Emergence and stability of spin-valley entangled quantum liquids in moiré heterostructures
Dominik Kiese, Finn Lasse Buessen, Ciarán Hickey +2
Twisting moiré heterostructures to the flatband regime allows for the formation of strongly correlated quantum states, since the dramatic reduction of the bandwidth can cause the r…
Thermal Hall signatures of non-Kitaev spin liquids in honeycomb Kitaev materials
Yong Hao Gao, Ciarán Hickey, Tao Xiang +2
Motivated by the recent surge of field-driven phenomena discussed for Kitaev materials, in particular the experimental observation of a finite thermal Hall effect and theoretical p…
Quantum skyrmions in frustrated ferromagnets
Vivek Lohani, Ciarán Hickey, Jan Masell +1
We develop a quantum theory of magnetic skyrmions and antiskyrmions in a spin-1/2 Heisenberg magnet with frustrating next-nearest neighbor interactions. Using exact diagonalization…
