Majorana corner modes in unconventional monolayers of the 1T-PtSe2 family
Haohao Sheng, Yue Xie, Quansheng Wu +5
In this work, we propose that Majorana zero modes can be realized at the corners of the two-dimensional unconventional insulator. We demonstrate that 1T-PtSe2 is a symmetry indicat…
Interfering Josephson diode effect in Ta2Pd3Te5 asymmetric edge interferometer
Yupeng Li, Dayu Yan, Yu Hong +17
Edge states in topological systems have attracted great interest due to their robustness and linear dispersions. Here a superconducting-proximitized edge interferometer is engineer…
Superconductivity in unconventional metals
Zhilong Yang, Haohao Sheng, Zhaopeng Guo +5
Based on first-principles calculations, we demonstrate that 1H/2H-phase transition metal dichalcogenides MX2 (M=Nb,Ta; X=S,Se,Te) are unconventional metals, which have an empty-sit…
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…
Magnetic field filtering of the hinge supercurrent in unconventional metal NiTe-based Josephson junctions
Tian Le, Ruihan Zhang, Changcun Li +11
Topological materials with boundary (surface/edge/hinge) states have attracted tremendous research interest. Besides, unconventional (obstructed atomic) materials have recently dra…
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…
