Definition

Proper noun A Soviet theoretical physicist who made fundamental contributions to many areas of physics, including low-temperature physics (superfluidity), quantum field theory, and condensed matter physics. He was awarded the Nobel Prize in Physics in 1962.

Usage

This term is used exclusively as a proper noun to refer to the historical figure, his work, or concepts and theories named after him. * Lev Davidovich Landau is considered one of the most influential theoretical physicists of the 20th century. * The textbook explained the Landau theory of second-order phase transitions. * Her research focuses on Landau levels in two-dimensional electron systems.

Advanced Usage
