Misfit layer compounds: a platform for heavily-doped two-dimensional transition metal dichalcogenides
Raphaël T. Leriche, Alexandra Palacio-Morales, Marco Campetella +14
Transition metal dichalcogenides (TMDs) display a rich variety of instabilities such as spin and charge orders, Ising superconductivity and topological properties. Their physical p…
Probing topological spin structures using light-polarization and magnetic microscopy
Till Lenz, Georgios Chatzidrosos, Zhiyuan Wang +12
We present an imaging modality that enables detection of magnetic moments and their resulting stray magnetic fields. We use wide-field magnetic imaging that employs a diamond-based…
Landau Theory for Non-Symmetry-Breaking Electronic Instability Coupled to Symmetry-Breaking Applied to Prussian Blue Analogue
Giovanni Azzolina, Roman Bertoni, Claude Ecolivet +3
Different types of ordering phenomena may occur during phase transitions, described within the universal framework of the Landau theory through the evolution of one, or several, sy…
Perturbation approach to ab initio effective mass calculations
Oleg Rubel, Fabien Tran, Xavier Rocquefelte +1
A degenerate perturbation approach for effective mass calculations is implemented in the all-electron density functional theory (DFT) package WIEN2k. The accuracy is tes…
First principles modeling of exciton-polaritons in polydiacetylene chains
Antonios M. Alvertis, Raj Pandya, Claudio Quarti +7
Exciton-polaritons in organic materials are hybrid states that result from the strong interaction of photons and the bound excitons that these materials host. Organic polaritons ho…
Shortcomings of meta-GGA functionals when describing magnetism
Fabien Tran, Guillaume Baudesson, Jesús Carrete +4
Several recent studies have shown that SCAN, a functional belonging to the meta-generalized gradient approximation (MGGA) family, leads to significantly overestimated magnetic mome…
