Entropy and the uncertainty principle
Get PDFWe generalize, improve and unify theorems of Rumin, and Maassen--Uffink about
classical entropies associated to quantum density matrices. These theorems
refer to the classical entropies of the diagonals of a density matrix in two
different bases. Thus they provide a kind of uncertainty principle. Our
inequalities are sharp because they are exact in the high-temperature or
semi-classical limit.Comment: 6 page

No full textSSRAT is a computer program for two-dimensional sociometric status determination with rating scales. For each person assessed, SSRAT computes probability distributions of the total scores for ‘sympathy’ (S), ‘antipathy’ (A), ‘social preference’ (P) and ‘social impact’ (I), and applies the criteria for sociometric status categorization
