Orbital dimerization-induced first-order structural phase transition: a case study in La $_{3}$ Ni $_{2}$ O $_{7}$

Xingchen Shen, Wei Ku

First-order structural phase transition is a common phenomenon in materials that qualitatively alters their physical properties. Yet, the abrupt first-order nature is usually unexp…

Charge order through crystallization of Frenkel excitons: realization in kagome metals

Ruoshi Jiang, Bartomeu Monserrat, Wei Ku

Charge order is a widely observed and representative example of spontaneous broken symmetries in quantum states of matter. Owing to the large intra-atomic Coulomb energy, the charg…

`Interaction annealing' to determine effective quantized valence and orbital structure: an illustration with ferro-orbital order in WTe $_{2}$

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…
