Mannque Rho
Encyclopedia
Mannque Rho (December 14, 1936 -) is a Korean theoretical physicist.
He has been contributed to theoretical nuclear/hadron physics and suggested Brown-Rho Scaling with Gerald E. Brown
which predicts how the masses of the hadrons disappear in hot and dense environments.

in 1936. He graduated from Kyunggi High School
and started
his college study at the political science department of Seoul National University
. And soon he moved to the United States
and
entered Clark University
. At first he registred for the pre-med study but later changed his major to chemistry and received his bachelor's degree in 1960.
During his college studies, he attended some lectures about the structure of nuclear by Ben Roy Mottelson
and Niels Bohr
who were visiting the university at that time. He was affected by them and this led him to study hadron physics. He received his Ph.D in nuclear physics
from University of California, Berkeley
in 1965. Next year he visited CEA Saclay
, France and met his future wife (German) and decided to settle down in France. And became a professor of that institute and has been there ever since.
He held many inviting positions and has been a visiting professor four times at State University of New York at Stony Brook
during 1973 to 1989.
He was a professor in School of Physics at Korea Institute for Advanced Study
from 2002 to 2003.
Currently, he is a research professor of theoretical physics, 'Expert Senior du CEA' and scientific counselor at CEA Saclay
, France and also a chair professor of Hanyang University
, South Korea from 2009.

in nuclear medium. QCD was poorly understood at that time and he explained how chiral symmetry appears in nuclear structure. In 1979 he and Gerald E. Brown
implemented chiral symmetry in an effective theory of the nucleon
in the form of chiral bag model according to which quarks exist freely in a bag surrounded by a pion
cloud. In 1991 Rho and Brown derived a scaling property of hadrons in hot and dense medium, now known as Brown-Rho scaling which predicted how the masses of the hadrons disappear in hot (early universe) and dense (neutron star
) environments.
The BR scaling has been tested experimentally in several electro-weak processes involving heavy nuclei. It has explained the CERN
heavy-ion experiments on dilepton production and is expected to explain some features from the experiments at RHIC. For the astro-hadron physics, it has possibilities to explain the supernovae explosions and the structure of compact stars. Rho is currently working on superdense hadronic QCD properties and astro-hadron physics.
