After the first demonstration of Bose Einstein condensation in the solid state in 2006 and the establishment of exciton polariton condensates in the wider scientific community, an intense interest has been attracted by this phenomenon at both theoretical and experimental level. This book presents in detail the different aspects of fundamental importance related to the polariton condensation. After an overview of the basic concepts for excitons, polaritons and condensates in and out of equilibrium, the book then considers a variety of experimental methods used in their study. A detailed theoretical analysis that supports observed experimental findings is also provided.

Konstantinos Lagoudakis obtained a BSc in Physics at the National Kapodistrian University of Athens in 2005 followed by an MSc in Optics and Photonics at Imperial College London in 2006. In 2010 he completed his PhD in Photonics at the Ecole polytechnique fédérale de Lausanne (EPFL) in the Laboratory of Quantum Optoelectronics, where he stayed for another year as a post-doctoral fellow. The outstanding quality of his PhD thesis led to the EPFL Doctorate Award and EPFL Press Distinction. Since 2012, he has been working on on-chip non-classical light sources and developing new technologies for quantum information processing in the Nanoscale and Quantum Photonics Laboratory at Stanford University as the recipient of the Swiss National Foundation advanced researcher fellowship.
