Tuning Incommensurate Charge Order in BaSrAl and BaEuAl
Prathum Saraf, Eleanor M. Clements, Danila Sokratov +14
The BaAl-type structure family is home to a vast landscape of interesting and exotic properties, with descendant crystal structures hosting a variety of electronic ground state…
Resolving Intervalley Gaps and Many-Body Resonances in Moiré Superconductor
Hyunjin Kim, Gautam Rai, Lorenzo Crippa +15
Magic-angle twisted multilayer graphene stands out as a highly tunable class of moiré materials that exhibit strong electronic correlations and robust superconductivity. However, u…
Altermagnetic splitting of magnons in hematite (-FeO)
Rhea Hoyer, P. Peter Stavropoulos, Aleksandar Razpopov +3
We develop a four-sublattice spin-wave theory for the -wave altermagnet candidate hematite (-FeO), considering both its easy-axis phase below and its weak ferromagnet…
Band representations in Strongly Correlated Settings: The Kitaev Honeycomb Model
Axel Fünfhaus, Mikel García-Díez, M. G. Vergniory +3
In the study of quantum spin liquids, the Kitaev model plays a pivotal role due to the fact that its ground state is exactly known as well as the fact that it may be realized in st…
Origin of the insulating state in the Kitaev candidate CuIrO
Ying Li, Roger D. Johnson, Yogesh Singh +2
Through a combination of crystal symmetry analysis and density functional theory calculations we unveil a possible microscopic origin of the unexpected insulating behavior reported…
