Encyclopedia
Keith Schwab is an American
physicist
born in St. Louis, Missouri
. His contributions are in the areas of nanoscience, ultra-low temperature physics, and quantum effects.
in 1990 and a Ph.D. in Physics from University of California, Berkeley
in 1996. He wrote a dissertation “Experiments with Superfluid Oscillators" under advisor Richard Packard, where he demonstrated an ultra-sensitive gyroscope based on the quantum properties of superfluid
helium. He joined the California Institute of Technology
in 1996 as a Sherman Fairchild Distinguished Postdoctoral Scholar. There he made the first observation of the quantum of thermal conductance which is the quantum mechanical limit for energy flow through single quantum channels An electron micrograph from this work resides in the permanent collection of the Museum of Modern Art
.
Schwab joined the U.S. National Security Agency
in 2000, and lead a group to study the quantum limits of mechanical structures. During which time he was named as a promising young innovator by Technology Review
.
In 2002, Schwab was named to the MIT
Technology Review
TR100
as one of the top 100 innovators in the world under the age of 35. In 2005, he was named a Young Global Leader by the World Economic Forum and attended the annual meeting in Davos, Switzerland in 2005, 2007, and 2008.
In 2006, Schwab moved to Cornell
as an associate professor of physics where his group focused on both the cooling of mechanical structures to near the quantum ground state, and the observation of motion which fundamentally avoids the Heisenberg Uncertainty Principle.
In 2009 he joined Caltech
as a professor of applied physics. His group explores the following topics: producing squeezed states of motion, exploring ultra-low dissipation superfluid resonators, ultra-sensitive microwave detection using graphene-based bolometers, and developing wide-band parametric amplifiers.

Superfluid
Superfluidity is a state of matter in which the matter behaves like a fluid without viscosity and with extremely high thermal conductivity. The substance, which appears to be a normal liquid, will flow without friction past any surface, which allows it to continue to circulate over obstructions and...
