Charge transfer empties the flat band in 4H-TaS -- except at the surface
Mihir Date, Hyeonhu Bae, Alex Louat +5
The 4H\textsubscript{b} polytype of TaS is a natural heterostructure of H and T-type layers. Intriguing recent evidence points towards a possibly chiral superconducting ground…

Tunable Octdong and Spindle-Torus Fermi Surfaces in Kramers Nodal Line Metals
Gabriele Domaine, Moritz H. Hirschmann, Kirill Parshukov +9
It has recently been proposed that all achiral non-centrosymmetric crystals host so-called Kramers nodal lines, which are doubly degenerate band crossings connecting time-reversal…

Momentum-Resolved Fingerprint of Mottness in Layer-Dimerized NbBr
Mihir Date, Francesco Petocchi, Yun Yen +20
In a well-ordered crystalline solid, insulating behaviour can arise from two mechanisms: electrons can either scatter off a periodic potential, thus forming band gaps that can lead…
