41. This is the so-called method of little groups of Wigner and Mackey. 42. They also describe the static Wigner functions of oscillator systems in 3D isotropic harmonic oscillator. 43. This method was originally formulated for studying resonances in nuclear scattering by Wigner and Eisenbud. 44. In 2010 he received the Wigner Medal. 45. For the harmonic oscillator, the time evolution of an arbitrary Wigner distribution is simple. 46. This unknown excitation was later dubbed " isospin " by Eugene Wigner in 1937. 47. So is the Jordan Wigner transformation. 48. Weinberg became a prot�g?of Wigner . 49. A refined version of the Weyl-Wigner association rule is proposed by Groenewold and Stratonovich. 50. In particular, Wigner 's theorem is a cornerstone in the mathematical formulation of quantum mechanics.
