Dr. Osvaldo Civitarese is an Emeritus Professor of Theoretical Physics at the University of La Plata, Argentina. He is an expert in nuclear structure and neutrino physics. During his tenure, he gave lectures in statistical mechanics, electromagnetism, quantum mechanics, and nuclear structure. He has published more than 300 research papers, 50 conference articles, and one book on modern physics for undergraduate students. He got national and international awards like the J. S. Guggenheim Foundation prize. He is a member of the Mexican Academy of Science and a former Alexander von Humboldt fellow. Dr. Manuel Gadella is a Professor of Physics at the University of Valladolid, Spain. He is an expert in mathematical physics. He is author of about 150 research papers and two books for undergraduate students. In collaboration with Prof. Arno Bohm (University of Texas at Austin), he wrote the book entitled "Dirac kets, Gamow vectors and Gelfand triplets" published in the Springer Lecture Notes in Physics.
