Marvin D. Girardeau is a quantum

Quantum

In physics, a quantum is the minimum amount of any physical entity involved in an interaction. Behind this, one finds the fundamental notion that a physical property may be "quantized," referred to as "the hypothesis of quantization". This means that the magnitude can take on only certain discrete...

Physicist

A physicist is a scientist who studies or practices physics. Physicists study a wide range of physical phenomena in many branches of physics spanning all length scales: from sub-atomic particles of which all ordinary matter is made to the behavior of the material Universe as a whole...

. One of Girardeau's achievements was to predict the existence of the Tonks-Girardeau gas

Tonks-Girardeau gas

In physics, a Tonks–Girardeau gas is a quantum degenerate Bose Gas in which the repulsive interactions between bosonic particles confined to one dimension dominate the physics of the system. It is named after physicists Marvin D. Girardeau and Lewi Tonks...

 in 1960. A Tonks-Girardeau gas was created in 2004, and its measured properties strikingly confirmed Girardeau's original predictions.

His research interests include the dynamics

Dynamics (mechanics)

In the field of physics, the study of the causes of motion and changes in motion is dynamics. In other words the study of forces and why objects are in motion. Dynamics includes the study of the effect of torques on motion...
