Moshinsky Física, Astronomía y Matemáticas Transition from quantum to classical behavior There is an increasing interest in the question of why typical quantum mechanical properties, such as those connected with the superpositionof states or diffraction patterns for material systems, are not observed on the classical macroscopic level. By discussing two simple modelproblems connected via the free-particle propagator, we show under what circumstances typical quantum effects that show up in these systemscan attain significant magnitudes so as to have a chance to be observable. The influence of the interaction with a dissipative environment willalso be considered, and the time scale where the effects reach their maximum and how they decay afterwards will be discussed. Furthermore,a comparison with recent scattering experiments will be given. 2005 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57064112 https://www.redalyc.org/journal/570/57064112/ https://www.redalyc.org/journal/570/57064112/html/ https://www.redalyc.org/journal/570/57064112/57064112.epub https://www.redalyc.org/journal/570/57064112/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
