Along with Robert Betts Laughlin and Daniel C. Tsui, who else was awarded the 1998 Nobel Prize in physics for their explanation of the fractional quantum Hall effect?
Daniel C. Tsui Daniel Chee Tsui (, born February 28, 1939, Henan Province, China) is a Chinese-born American physicist whose areas of research included electrical properties of thin films and microstructures of semiconductors and solid-state physics. He was previously the Arthur LeGrand Doty Professor of Electrical Engineering at Princeton University and adjunct senior research scientist in the Department of Physics at Columbia University, where he was a visiting professor from 2006 to 2008. Currently, he is a research professor at Boston University. In 1998, along with Horst L. Störmer of Columbia and Robert Laughlin of Stanford, Tsui was awarded the Nobel Prize in Physics for his contributions to the discovery of the fractional quantum Hall effect.
CHSH inequality In physics, the CHSH inequality can be used in the proof of Bell's theorem, which states that certain consequences of entanglement in quantum mechanics cannot be reproduced by local hidden variable theories. Experimental verification of violation of the inequalities is seen as experimental confirmation that nature cannot be described by local hidden variables theories. CHSH stands for John Clauser, Michael Horne, Abner Shimony, and Richard Holt, who described it in a much-cited paper published in 1969 (Clauser "et al.", 1969). They derived the CHSH inequality, which, as with John Bell's original inequality (Bell, 1964), is a constraint on the statistics of "coincidences" in a Bell test experiment which is necessarily true if there exist underlying local hidden variables (local realism). This constraint can, on the other hand, be infringed by quantum mechanics.
