Quantum engines must break down
London UK (SPX) Jun 28, 2013
Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and needs to be modified, according to new research from University College London (UCL) and the University of Gdansk. The work establishes new laws in the rapidly emerging field of quantum thermodynamics. The findings, published in Nature Communications, have wide applications in small systems, from nanoscale engines and quantum technologies, to biological motors and systems found in the body. ... read more
