Zig-Zag magnetic order and potential Kitaev interactions in the spin-1 honeycomb lattice KNiAsO
K. M. Taddei, V. O. Garlea, A. M. Samarakoon +6
Despite the exciting implications of the Kitaev spin-Hamiltonian, finding and confirming the quantum spin liquid state has proven incredibly difficult. Recently the applicability o…
Bootstrapped Dimensional Crossover of a Spin Density Wave
Anjana M. Samarakoon, J. Strempfer, Junjie Zhang +8
Quantum materials display rich and myriad types of magnetic, electronic, and structural ordering, often with these ordering modes either competing with one another or 'intertwining…
Extraction of the interaction parameters for RuCl from neutron data using machine learning
Anjana M. Samarakoon, Pontus Laurell, Christian Balz +6
Single crystal inelastic neutron scattering data contain rich information about the structure and dynamics of a material. Yet the challenge of matching sophisticated theoretical mo…
Anomalous magnetic noise in imperfect flat bands in the topological magnet Dy2Ti2O7
Anjana M. Samarakoon, S. A. Grigera, D. Alan Tennant +8
The spin ice compound Dy_2Ti_2O_7 stands out as the first topological magnet in three dimensions, with its tell-tale emergent fractionalized magnetic monopole excitations. Its real…
Structural magnetic glassiness in spin ice DyTiO
Anjana M. Samarakoon, Andre Sokolowski, Bastian Klemke +14
The spin ice compound DyTiO is well-known to realise a three-dimensional Coulomb spin liquid with magnetically charged monopole excitations. Its fate at low temperature…
Static and dynamic magnetic properties of honeycomb lattice antiferromagnets NaTeO, = Co and Ni
Anjana M. Samarakoon, Qiang Chen, Haidong Zhou +1
The magnetic structures and spin dynamics of NaCoTeO and NaNiTeO are investigated by means of elastic and inelastic neutron scattering measureme…
Witnessing entanglement in quantum magnets using neutron scattering
A. Scheie, Pontus Laurell, A. M. Samarakoon +6
We demonstrate how quantum entanglement can be directly witnessed in the quasi-1D Heisenberg antiferromagnet KCuF. We apply three entanglement witnesses --- one-tangle, two-tan…
Machine Learning Assisted Insight to Spin Ice DyTiO
Anjana M Samarakoon, Kipton Barros, Ying Wai Li +8
Complex behavior poses challenges in extracting models from experiment. An example is spin liquid formation in frustrated magnets like DyTiO. Understanding has been hin…
Constraining the Parameter Space of a Quantum Spin Liquid Candidate in Applied Field with Iterative Optimization
William M. Steinhardt, Zhenzhong Shi, Anjana Samarakoon +7
The quantum spin liquid (QSL) state is an exotic state of matter featuring a high degree of entanglement and lack of long-range magnetic order in the zero-temperature limit. The tr…
Exotic magnetic field-induced spin-superstructures in a mixed honeycomb triangular lattice system
V. Ovidiu Garlea, Liurukara D. Sanjeewa, Michael A. McGuire +7
The temperature-magnetic-field phase diagram of the mixed honeycomb triangular lattice system KMn(VO)CO is investigated by means of magnetization, hea…
Comprehensive study of the dynamics of a classical Kitaev spin liquid
A. M. Samarakoon, A. Banerjee, S. -S. Zhang +5
We study the spin- Kitaev model in the classical () limit using Monte Carlo simulations combined with semi-classical spin dynamics. We discuss differences and simi…
Spin Jam: a quantum-fluctuation-induced glassy state of a frustrated magnet
Junjie Yang, Anjana Samarakoon, Sachith Dissanayake +8
Since the discovery of spin glasses in dilute magnetic systems, their study has been largely focused on understanding randomness and defects as the driving mechanism. The same para…
