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…
Exact downfolding and its perturbative approximation
Jonas B. Profe, Jakša Vučičević, P. Peter Stavropoulos +3
Solving the many-electron problem, even approximately, is one of the most challenging and simultaneously most important problems in contemporary condensed matter physics with vario…
Site-polarized Mott phases competing with a correlated metal in twisted WSe
Siheon Ryee, Lennart Klebl, Gautam Rai +9
Twisted WSe hosts superconductivity, metal-insulator phase transitions, and field-controllable Fermi-liquid to non-Fermi-liquid transport properties. In this work, we use dynam…
Microscopic origin of the magnetic interactions and their experimental signatures in altermagnetic LaOMnSe
Laura Garcia-Gassull, Aleksandar Razpopov, Panagiotis Peter Stavropoulos +2
Altermagnets (AM) are a recently introduced type of magnets, with no net magnetization like antiferromagnets, but displaying a non-relativistic Zeeman splitting in reciprocal space…
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…
