Eliade Stefanescu, graduate of Faculty of Electronics, Section of Physicist Engineers in 1970, and PhD in Theoretical Physics in 1990, is a professional with multidisciplinary openness. In 1975 he followed a specialization course in physics of semiconductor devices, and, as a Scientist from 1976, and a Senior Scientist III from 1978, he worked in the field of dynamical characterization of semiconductor devices. From 1978, he worked in physics of optoelectronic devices, especially in optical bistability. From 1987, and from 1990 as a Senior Scientist II, he worked in the field of open quantum physics. In 1989 he predicted a phenomenon of amplification of a coherent electromagnetic field on the account of the environmental heat, and in 1991 discovered that the penetrability of a potential barrier can be increased by coupling to a dissipative system – thus, he described the decay spectrum of some cold fission modes. As a Senior Scientist I, from 1997 he developed a microscopic theory of open quantum systems, discovered a physical principle for the heat conversion into usable energy, invented semiconductor devices, and gave an analytical, microscopic description of the involved phenomena. In 2014, he produced a unitary relativistic quantum theory. In the years 1995-2000, he held a course called Dissipative Systems, in a program of the Polytechnic University of Bucharest for the master degree. He collaborated with scientists from the Institute of Theoretical Physics in Giessen, Germany, and the Department of Theoretical Nuclear Physics of the Royal Institute of Technology in Stockholm, Sweden.
