%0 Journal Article %T Reflections on Friction in Quantum Mechanics %A Yair Rezek %J Entropy %D 2010 %I MDPI AG %R 10.3390/e12081885 %X Distinctly quantum friction effects of three types are surveyed: internalfriction, measurement-induced friction, and quantum-fluctuation-induced friction. We demonstrate that external driving will lead to quantum internal friction, and critique the measurement-based interpretation of friction. We conclude that in general systems will experience internal and external quantum friction over and beyond the classical frictional contributions. %K quantum friction %K dissipation %K open system %U http://www.mdpi.com/1099-4300/12/8/1885
