Single electron devices as Maxwell’s demons

Vous êtes cordialement invités à la conférence de Jonne KOSKI, Enliss Group, Nanophysics, ETH, Zürich, Switzerland, organisée par l'IPCMS.

Résumé :

The second law of thermodynamics dictates that entropy, the measure of disorder,
cannot decrease. One of the direct implications of the law is the impossibility of
machines of perpetual motion. In 1867 J. C. Maxwell introduced a simple thought
experiment, today known as Maxwell’s demon, to challenge this law. Further
theoretical work by L. Szilard in 1929 and R. Landauer in 1961 led to the
understanding of the role of information in thermodynamics. Yet only since the
beginning of this decade, first quantitative experiments on Maxwell’s demons were
demonstrated. This presentation will cover such experiments, specifically focusing
on ones based on single-electron transport in low temperature nanoelectronics.
