The Laboratory Pierre Aigrain (LPA – UMR 8551) is a leading physics institute in the field of condensed matter. The main research domains are related to the optical (from the terahertz to the ultraviolet) and electrical properties (from DC to gigahertz frequencies) of semiconductor and metallic nanostructures, ranging from quantum dots to carbon nano-materials. These fundamental studies are equally developed experimentally and theoretically and target the exploitation the emerging quantum properties (both optically and electrically) of matter on the nanometer scale. These investigations open the path towards a range of diverse applications such as quantum information and molecular electronics.

The LPA is affiliated to the CNRS, the Ecole Normale Superieure (ENS), University Pierre and Marie Curie (UPMC) and University Paris Diderot (UPD). The LPA, directed by Jean-Marc Berroir, currently has typically 70 members which includes 24 permanent academic staff members, 5 emeritus professors, 8 supporting staff, 10 postdoctoral research associates and 20 postgraduate students.

Collaborations

The LPA investigations on nanostructered condensed matter systems is implicated in a network of collaborations on a national (in particular through ANR contracts) and international level. The latter includes research with leading universities in Berlin, Vienna, Geneva, Cambridge, Tokyo, New York and Helinski. The research at the LPA is supported by access to a network of clean rooms in the Paris area as well as a partnership with the nanotechnology national center at the "Laboratoire de Photonique et Nanostructures (LPN)"

Recent research at the LPA

1) The mesoscopic physics team has recently shown that two independent single electron sources can emit indistinguishable electrons on-demand, opening up the possibility of new architectures for quantum cryptography and calculus.

2) The coherent and nonlinear optic team has successfully measured for the first time how the atomic coil angle (or chirality) of a carbon nanotube can modify its’ optical absorption.
