DOI: 10.1021/acsnano.9b02399
Abstract: Solid-state thermoelectrics are of great interest because they directly convert between thermal and electrical energy. However, wider application of thermoelectrics is dependent upon improving their performance. Anderson localization of charge carriers has been generally perceived… read more here.

DOI: 10.1038/s42005-017-0001-4
Abstract: In quantum systems, signatures of multifractality are rare. They have been found only in the multiscaling of eigenfunctions at critical points. Here we demonstrate multifractality in the magnetic field-induced universal conductance fluctuations of the conductance… read more here.
