Why this life matters
His work connects experimental preparation with multiple signatures of a new quantum state, rather than identifying condensation with low temperature alone.
Timeline

Cornell was born on 19 December.
Rubidium condensate
The Boulder team observed the dilute-gas condensate.
Physics Nobel
Shared the award with Carl Wieman and Wolfgang Ketterle.
From university training to single-ion measurements
Eric Allin Cornell was born in Palo Alto, California, in 1961 and grew up largely in Cambridge, Massachusetts. After undergraduate study at Stanford, he returned to Cambridge for graduate work at MIT. There he joined David Pritchard’s group, working on precision measurements using trapped ions. His autobiography describes the practical difficulty of detecting and comparing individual ions. This was valuable preparation for a career in atomic physics, but it did not yet supply the laser techniques that he wanted to learn in a postdoctoral position.
A Boulder opportunity and a new collaboration
Cornell’s search for postdoctoral work brought him to Boulder, where a visit to NIST led to an introduction to Carl Wieman at JILA. Cornell was drawn to Wieman’s laser-cooling experiment and joined the work on ultracold atoms. The collaboration combined different experiences within a larger team. Its eventual 1995 paper named Michael Anderson, Jason Ensher, Michael Matthews, Wieman and Cornell. The result should therefore be described as an experimental group achievement, rather than a condensate created by two prizewinning researchers without students or colleagues.
A condensate identified through several signatures
The team confined rubidium-87 atoms magnetically and used evaporative cooling. The 1995 report identified a narrow low-velocity component above a broader thermal distribution, an abrupt increase of that component with further cooling and an anisotropic expansion consistent with the trapped ground state. These observations supplied more than a claim of an extremely low temperature. Their joint lecture later explains why seeing different behaviour in the condensate and thermal portions was an important cross-check using the same imaging system.
Recognition and the meaning of the experiment
Cornell shared the 2001 Nobel Prize in Physics with Wieman and Wolfgang Ketterle for dilute-gas condensation and early studies of the condensates. The achievement opened an experimental way to study a collective quantum state with controllable atomic gases. Its significance does not depend on imagining that the atoms stopped moving altogether. A condensate occupies a quantum state, with behaviour constrained by its trap and interactions. Cornell’s career is a useful example of how careful apparatus work and several mutually reinforcing observations can turn a long-standing theoretical possibility into an experimental research field.
Quick answers
Frequently asked questions about Eric Cornell
- Who collaborated with Eric Cornell on the 1995 condensate?
- The original paper names Michael Anderson, Jason Ensher, Michael Matthews, Carl Wieman and Eric Cornell.
- Was the condensate identified only by its low temperature?
- No. The report combined a narrow component, its changing population and a nonthermal anisotropic velocity distribution.
