Supercell-size scaling of moiré band flatness
Peilong Hong, Yuge Qiu, Wenjing Li +9
In moiré superlattices, the band flatness governs the degree of wave localization, which is central to harnessing emergent phenomena and designing functional meta-devices. While re…

Correlation Matrix Method for Phonon Quasiparticles
Wenjing Li, Yong Lu, Fawei Zheng
Phonon anharmonicity is ubiquitous in real materials and is crucial for understanding thermal properties and phase stability. In this work, we show that anharmonic phonon modes can…
