in nonrelativistic quantum mechanics

L. I. Mandelshtam, I. E. Tamm

1945

Comments

The main result of the paper is the inequality (11), which is called now Mandelshtam-Tamm inequality.
This fundamental inequality is a special case of the certainty principle, applied to the quantum evolution in the Schrödinger representation.
