`Interaction annealing' to determine effective quantized valence and orbital structure: an illustration with ferro-orbital order in WTe
Ruoshi Jiang, Fangyuan Gu, Wei Ku
Correlated materials are known to display qualitatively distinct emergent behaviors at low energy. Conveniently, upon absorbing rapid quantum fluctuations, these rich low-energy be…

2D ferroelectricity accompanying antiferro-orbital order in semi-metallic WTe
Fangyuan Gu, Ruoshi Jiang, Wei Ku
The first switchable electric polarization in metals was recently discovered in bilayer and trilayer WTe2. Strangely, despite the tininess of the ordered polarization, the ferroele…
