What was Ettore Majorana's profession?
Landau–Zener formula: The Landau–Zener formula is an analytic solution to the equations of motion governing the transition dynamics of a 2-level quantum mechanical system, with a time-dependent Hamiltonian varying such that the energy separation of the two states is a linear function of time. Ettore Majorana: Ettore Majorana ( ; ] ; born on 5 August 1906 – probably died after 1959) was an Italian theoretical physicist who worked on neutrino masses.
