Our vision:

To address the need for a fundamental and interdisciplinary approach to modern science

We offer a full range of services addressed to develop synergistic relations with the existing areas of research experience at an organization and/or to enhance complementarities as well as to broaden the scope of research to include fundamental aspects.

Our services include designing and conceiving research, making theoretical studies, developing theories and performing exploratory fundamental work, as well as delivering solutions to challenging problems through analytical methods, quantum formulations and mathematical modelling, including simulation. On the experimental strand we deliver consultancy services related to interpretation of experimental results, evaluation of experiments in terms of consistency with the theories being explored, and to building theoretical creativity backing experimental work.

On the strategic side we investigate and assess new applications of running R & D - including high-risk R & D, and their market potential; formulate and develop commercialization strategies; explore and analyze scientific topics that will be relevant to the industry; formulate strategic plans and build research agendas; work on transference of fundamental research to practical ways of applying it; and plan/implement strong dissemination and communication strategies of the knowledge produced in scientific & technology efforts addressed and tailored to a variety of targets: policy makers, scientists not directly involved with the matter under study, industry, business community, and general public. And conduct project management. At Sapienza we offer high added value since we are imbedded in both research and in getting this research managed the best in favour of the scientific, industry and business communities.

We also provide educational material, courses, seminars, and documentation on both specific and general matters - we transparently search/scan a variety of relevant reliable sources, compile the information and concisely communicate it to support R & D operation.

Our credentials:

At Sapienza we maintain long term research and productivity trends. We have developed theoretical research programs and have obtained important results over a wide range of topics within the frontier physics and related technologies, some of them are: optical electrical and magnetic properties of semiconductors; amorphous semiconductors; laser diodes -noise and quantum concerns; photodetectors - plasma optical effect, operation speed, refractive index; gasdynamic lasers; interaction of atoms with laser; optical solitons arising from the highly nonlinear Schroedinger equation and solitons in BECs; photon mass; quantum phenomena in electronic components; fundamental limits of interaction of radiation with matter; formalisms to model physical processes; itinerant-electron metamagnetic materials; electron optics -relativistic motion of an electron submitted to a perpendicular field. And we have successfully tackled a series of themes in nanoscience: carbon nanotubes, nanowires, quantum dots, and STM. The results of this research work have been published in recognized peer-reviewed international journals as Modern Physics Letters B or Optik among others: we have published over 140 papers always in peer reviewed international journals. Our papers rank among the Top25 Hottest Articles of Sciencedirect-Optik: in the last quarter of 2005 we have one paper dealing with carbon nanotubes and the other with photonics (photon mass studies) and in the first quarter of 2006 one paper on materials with negative refractive index appears in the third position and also in the rest of 2006 quarters in different positions. Sapienza calls on existing relationships with other major research universities and research labs for partners to treat large and complex problems where complementary expertise is required.
