Unconventional phonon spectra and obstructed edge phonon modes
Ruihan Zhang, Haohao Sheng, Junze Deng +3
Based on the elementary band representations (EBR), some topologically trivial materials are classified as unconventional ones (obstructed atomic limit), where the EBR decompositio…

Ferroelectric metals in 1T/1T'-phase transition metal dichalcogenide MTe2 bilayers (M = Pt, Pd, and Ni)
Haohao Sheng, Zhong Fang, Zhijun Wang
Ferroelectricity and metallicity cannot coexist due to the screening effect of conducting electrons, and a large number of stable monolayers with 1T/1T phase lack sponta…

Hinge Majorana Flat Band in Type-II Dirac Semimetals
Yue Xie, Xianxin Wu, Zhong Fang +1
Type-II Dirac semimetals exhibit a unique Fermi surface topology, which allows them to host novel topological superconductivity (TSC). We reveal a novel inter-orbital superconducti…
