Robert Betts Laughlin (born November 1, 1950) is an American physicist. He is the Anne T. andRobert M. Bass Professor ofPhysics andApplied Physics atStanford University.[1] Along withHorst L. Störmer ofColumbia University andDaniel C. Tsui ofPrinceton University, he was awarded a share of the 1998Nobel Prize inphysics for their explanation of thefractional quantum Hall effect.

In 1983, Laughlin was first to provide amany bodywave function, now known as theLaughlin wavefunction, for thefractional quantum Hall effect, which was able to correctly explain the fractionalized charge observed in experiments. This state has since been interpreted as the integer quantum Hall effect of thecomposite fermion.[2]

His 2017 paper, "Pumped thermal grid storage with heat exchange"[3] inspired Project Malta atGoogle X and subsequently Malta inc.[4]

Biography

[edit]

Laughlin was born inVisalia, California. He earned aB.A. inmathematics at theUniversity of California, Berkeley in 1972, and hisPh.D. in physics in 1979 at theMassachusetts Institute of Technology (MIT). Between 2004 and 2006,[5] he served as the president ofKAIST inDaejeon,South Korea.

Laughlin published a book entitledA Different Universe: Reinventing Physics from the Bottom Down in 2005. The book argues foremergence as a replacement forreductionism, in addition to general commentary on hot-topic issues.
