Anionic Character of the Conduction Band of Sodium Chloride
Christopher C. Leon, Abhishek Grewal, Klaus Kuhnke +2
The alkali halides are ionic compounds. Each alkali atom donates an electron to a halogen atom, leading to ions with full shells. The valence band is mainly located on halogen atom…
Character of electronic states in the transport gap of molecules on surfaces
Abhishek Grewal, Christopher C. Leon, Klaus Kuhnke +2
We report on scanning tunneling microscopy (STM) topographs of individual metal phthalocyanines (MPc) on a thin salt (NaCl) film on a gold substrate, at tunneling energies within t…
Machine-learning-inspired quantum optimal control of nonadiabatic geometric quantum computation via reverse engineering
Meng-Yun Mao, Zheng Cheng, Yan Xia +2
Quantum control plays an irreplaceable role in practical use of quantum computers. However, some challenges have to be overcome to find more suitable and diverse control parameters…
Rich Magnetic Phase Diagram of Putative Helimagnet SrFeO
Nikita D. Andriushin, Justus Grumbach, Jung-Hwa Kim +14
The cubic perovskite SrFeO was recently reported to host hedgehog- and skyrmion-lattice phases in a highly symmetric crystal structure which does not support the Dzyaloshinskii…
Single crystal synthesis, structure, and magnetism of PbCu(PO)O
P. Puphal, M. Y. P. Akbar, M. Hepting +4
The recent claim of superconductivity above room temperature in PbCu(PO)O with 0.9 < < 1 (referred to as LK-99) has sparked considerable interest. To minim…
Orbitally controlled quantum Hall states in decoupled two-bilayer graphene sheets
Soyun Kim, Dohun Kim, Kenji Watanabe +3
We report on integer and fractional quantum Hall states in a stack of two twisted Bernal bilayer graphene sheets. By exploiting the momentum mismatch in reciprocal space, we suppre…
