A single and isolated electron has a clear electrical charge, magnetic moment and mass, and its free movement can be precisely predicted. Spanish scientists fabricated a nanoscale artificial material manipulating atoms one after the other and discovered that electrons can become heavier. Heavy electrons are promising particles which endow new functionalities to novel materials. This study is the result of an international collaboration lead by the Instituto de Nanociencia de Aragón and the Instituto de Ciencia de Materiales de Aragón (ICMA), in which scientists at CIC nanoGUNE participated, together with members of the Centro de Física de Materiales (CFM) in San Sebastian, and the Charles University and Czech Academy of Sciences, in the Czech Republic.
