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 ...
High-voltage direct current cables which can efficiently transport electricity over long distances play a vital role in our electricity supply. Optimizing their performance is therefore an important challenge. With that aim ...
