Prof. Garcia's experiments at Queens College
with photons and microwave radiation offered a
powerful demonstration of the resemblance
between light and matter established by
quantum theory. In their experiments, the
researchers showed that it was possible to
momentarily trap photons, the elemental
components of light and all electromagnetic
radiation, in a disordered medium. By shooting
microwave radiation through a tube filled with
aluminum and Teflon balls and monitoring the
energy signature that passed through them,
they found that some of the photons were
briefly "localized," stored in the pellets.
Prof. Hans Christian von Baeyer, an author and
physics professor at the College of William
and Mary, assessed the discovery in the
May-June 1992 issue of the magazine The
Sciences. Prof. von Baeyer said the finding
capped a decades-long effort to show that the
theories of Prof. Phillip Warren Anderson, who
won the 1977 Nobel Prize in Physics, were
"applicable not only to electron waves but
also to light waves and even sound." In 1958,
Prof. Anderson predicted that electrons could
be trapped in a crystal impregnated with
randomly spaced impurity atoms. The effect is
now known at Anderson localization.
Along with Arthur Damask, a colleague at
Queens College, Prof. Garcia was co-author of
a popular textbook, "Physics for Computer
Science Students" (Springer-Verlag, New York),
which examines classical and quantum physics,
then uses those concepts to explain the inner
workings of the microprocessors at the heart
of computers and other electronic devices.
Prof. Narciso Garcia was born on September 4,
1940 in Burgos, Spain, and came to the United
States to study at Marist College in
Poughkeepsie, NY, where he earned a bachelor's
degree in 1963. In 1969, he received a Ph.D.
in physics from the State University of New
York at Stony Brook. He joined the faculty of
Queens College that year and became a driving
force in the creation of a graduate physics
program there. He was adviser to the program's
students until his death in 1996 at the age of
55.
