Machine Learning of Topological Insulator and Anderson Insulator in One-Dimensional Extended Su-Schrieffer-Heeger Chain
Zhekai Yin, C. K. Ong
We study disorder effects in the extended Su-Schrieffer-Heeger (SSH) model using a convolutional neural network (CNN) trained on reduced correlation matrices (RCMs) of disorder-fre…
Accurate Nanoscale Mapping of Electric Fields across Random Grain Boundaries in Polycrystalline Oxides Using Precession-Assisted 4D-STEM
Sangjun Kang, Hyeyoung Cho, Maximilian Töllner +12
Space charge layers (SCLs) at grain boundaries play a crucial role in modulating local electric fields and influencing the functional properties of materials, such as oxygen vacanc…
Photoabsorption Cross Sections studied within the axially deformed Relativistic Quasiparticle Finite Amplitude Framework
C. Chen, Y. F. Niu, R. Xu +1
Photoabsorption cross sections for 235 stable nuclei, ranging from Ca to Bi, were investigated by the quasiparticle finite amplitude method (QFAM) based on the axial…
Transmission of low energy electrons through a polyethylene terephthalate 800-nm diameter nanocapillary
Li Pengfei, Liu Wanqi, Ha Shuai +14
The transmission of 2-keV electrons through a polyethylene terephthalate (PET) nanocapillary with a diameter of 800 nm and a length of 10 μm is studied. The transmitted electrons…
