- Approaches for Low-Energy Spin Hamiltonians
Kira Riedl, Ying Li, Roser Valenti +1
Implicit in the study of magnetic materials is the concept of spin Hamiltonians, which emerge as the low-energy theories of correlation-driven insulators. In order to predict and e…
On the saw-tooth torque in anisotropic magnets: Application to -RuCl
Kira Riedl, Ying Li, Stephen M. Winter +1
The so-called "Kitaev candidate" materials based on and metals have recently emerged as magnetic systems displaying strongly anisotropic exchange interactions reminis…
Data-driven Local Control Design using Optimization and Machine Learning Techniques
Stavros Karagiannopoulos, Petros Aristidou, Gabriela Hug
The optimal control of distribution networks often requires monitoring and communication infrastructure, either centralized or distributed. However, most of the current distributio…
Role of Hydrogen in the spin-orbital-entangled quantum liquid candidate HLiIrO
Ying Li, Stephen M. Winter, Roser Valenti
Motivated by recent reports of HLiIrO as a spin-orbital-entangled quantum liquid, we investigate via a combination of density functional theory and non-perturbative exa…
Relaxation dynamics in the one-dimensional organic charge-transfer salt δ-(EDT-TTF-CONMe)Br
J. K. H. Fischer, P. Lunkenheimer, C. Leva +6
A detailed investigation of the charge-ordered charge-transfer salt δ-(EDT-TTF-CONMe)Br by thermal-expansion measurements and dielectric spectroscopy reveals three dyna…
Detuning the Honeycomb of -RuCl: Pressure-Dependent Optical Studies Reveal Broken Symmetry
Tobias Biesner, Sananda Biswas, Weiwu Li +10
The honeycomb Mott insulator -RuCl loses its low-temperature magnetic order by pressure. We report clear evidence for a dimerized structure at GPa and observe the brea…
