Research Topic: Fluctuationinduced Phenomena

Short description: 
Fluctuationinduced interactions are phenomena arising from classical and quantum fluctuations. In the simplest form,
they consist in mesoscopic forces between two or more electrically neutral objects, the sign and the strength of which
strongly depend on the system and its geometry. A paradigmatic example is the Casimir effect between two parallel mirrors
at zero temperature. In this case, the force arises from electromagnetic quantum vacuum fluctuations: the outward radiation
pressure exerted by virtual photons between the mirrors is smaller than the inward pressure produced by virtual photons outside,
resulting in a net attractive force.
Fluctuations are also known for being responsible for the appearance of nonconservative forces between moving objects as well as
for the exchange of heat via radiation between vacuumseparated bodies at different temperatures.
Despite the fact that theories describing this kind of interactions were already formulated a long time ago, some relevant
controversies still exist. Different approaches have been used and several contradictory results are found in the literature
predicting not only different expressions with different dependencies on the physical parameters but also, in some cases,
querying the mere existence of these interactions. All theoretical methods are complicated by features such as nonadditivity
and the fact of dealing with macroscopic objects.
These, and other dispersive phenomena are of great importance in different areas of physics, ranging from quantum computation to
gravity, and their exact knowledge is rapidly becoming important for the characterization of modern experimental setups and for
the opportunities and challenges that they offer to nanotechnology. Solutions to problems and new ideas proposed by this research
hugely impact on all nanodisciplines and, in general, on all sciences that deal with nanotechnologies.
In our group we pursue an intensive theoretical and computational investigation of the role of equilibrium and nonequilibrium
fluctuationsinduced interactions in physical systems, providing new understanding and designs of new interesting setups. This
research leads to an increase of knowledge on fluctuationinduced interactions which is essential for designing and controlling
future performant devices. Starting from recent theoretical and experimental investigations showing that such interactions are
tunable in strength and sign, this work will also open new perspectives to investigate aspects of quantum field theory and
condensedmatter physics.
