Eric Cornell and the Achievement of Bose-Einstein Condensation
Eric Allin Cornell is a distinguished American physicist whose work has fundamentally altered our understanding of matter at ultra-low temperatures. He is most renowned for synthesizing the first Bose-Einstein condensate (BEC)—a unique state of matter where atoms are cooled to temperatures near absolute zero, causing them to collapse into a single quantum state.
This groundbreaking achievement, realized in 1995 alongside colleague Carl E. Wieman, earned Cornell a share of the 2001 Nobel Prize in Physics. The prize was awarded to Cornell, Wieman, and Wolfgang Ketterle for their work on the condensation of dilute gases of alkali atoms and their subsequent studies into the properties of these condensates.

Early Life and Academic Journey
Born on December 19, 1961, in Palo Alto, California, Eric Cornell grew up in an academic environment. His father was a professor of civil engineering at the Massachusetts Institute of Technology (MIT), leading the family to move to Cambridge, Massachusetts, during his childhood. Cornell's early education took place at the Cambridge Rindge and Latin School before he returned to California to graduate from Lowell High School, a magnet school for academically gifted students.
Cornell pursued his undergraduate studies at Stanford University, where he worked as an assistant in various low-temperature physics groups. Despite his success in the lab, he briefly explored interests in literature and politics, including a nine-month period volunteering as an English teacher and studying Chinese in China and Taiwan. He eventually returned to physics, graduating with honors and distinction in 1985.
For his doctoral studies, Cornell returned to MIT under the guidance of David E. Pritchard. His PhD thesis, completed in 1990, focused on mass spectroscopy (the study of the mass-to-charge ratio of ions) using single ion cyclotron resonance. While his research aimed to measure the mass of the electron neutrino from the beta decay of tritium, he did not ultimately determine the neutrino's mass.
The Path to the Nobel Prize
Following his PhD, Cornell joined Carl Wieman at the University of Colorado Boulder as a postdoctoral researcher. While working on a small laser cooling experiment, Cornell developed a strategy to combine laser cooling (using light to slow down atoms) and evaporative cooling (removing the hottest atoms from a trap) within a magnetic trap.
This innovative approach led to the successful creation of a Bose-Einstein condensate in 1995. This discovery provided the first experimental evidence of a state of matter predicted decades earlier, leading to Cornell's permanent appointment at JILA and the National Institute of Standards and Technology (NIST).
Cornell's research continued to evolve; in 1997, Deborah S. Jin joined his group at JILA, eventually leading the team that produced the first fermionic condensate in 2003.
Professional Recognition and Personal Life
Throughout his career, Cornell has received numerous prestigious accolades, including the Lorentz Medal (1998), the Benjamin Franklin Medal in Physics (2000), and the King Faisal International Prize in Science (1997). He is a Fellow of the American Academy of Arts and Sciences and the American Physical Society.
On a personal note, Cornell married Celeste Landry in 1995. In 2004, he faced a significant health crisis when he contracted necrotizing fasciitis (a severe bacterial infection of the deep fascia), which resulted in the amputation of his left arm and shoulder. Despite this, he returned to his professional work by April 2005 and remains active in his community, including participating in the Bolder Boulder road race.

Frequently Asked Questions
What is a Bose-Einstein condensate?
A Bose-Einstein condensate is a state of matter formed when a gas of bosons is cooled to temperatures very close to absolute zero, causing a large fraction of the atoms to occupy the lowest quantum state, effectively behaving as a single quantum entity.
Who shared the Nobel Prize with Eric Cornell?
Eric Cornell shared the 2001 Nobel Prize in Physics with Carl E. Wieman and Wolfgang Ketterle.
Where does Eric Cornell currently conduct his research?
He is a professor at the University of Colorado Boulder and a NIST fellow, with his laboratory located at JILA.
What techniques were used to create the first BEC?
The first BEC was created by combining laser cooling and evaporative cooling within a magnetic trap to reach the necessary ultra-low temperatures.
What was the focus of Eric Cornell's PhD thesis?
His 1990 thesis focused on mass spectroscopy using single ion cyclotron resonance, specifically attempting to measure the mass of the electron neutrino.
