A team of scientists, led by Dr. David Hsieh from the California Institute of Technology, have observed evidence of stable Hubbard excitons in a photo-doped antiferromagnetic Mott insulator. The findings of their study are ...
Mott insulators are a peculiar class of materials with structures that should theoretically conduct electricity, but that are instead insulators. These materials contain strongly correlated electrons, which can generate highly ...
Physicists have observed a novel quantum effect termed "hybrid topology" in a crystalline material. This finding opens up a new range of possibilities for the development of efficient materials and technologies for next-generation ...
