Abstract

The research project is focused on quantum effects in networks for identical particles. This area of research shows an exponential growth phase due to two factors: (i) technological development in the last decade has allowed to manufacture microscopic photonic networks and (ii) recent years have seen the rise of the concept called BosonSampling followed by spectacular proof of principle experiments.In recent years we have developed an approach to study the behavior of identical particles (bosons and fermions) in linear networks, which puts us on the forefront of research in this area. We will continue to deepen our understanding of behavior identical particles in quantum networks, use and generalize our approach, and search for new effects.We are witnessing the establishment of networks of international collaboration in the project area. Therefore, a significant part of the project involves collaborations with foreign researchers.The main lines of research, interconnected to each other, are:1. Behavior of partially distinguishable identical particles in unitary linear networks and the Boson Sampling; 2. Dissipative networks for identical particles, loss of particles and the ``Permanent on top" conjecture; 3. Characterizing of M-mode network with N arbitrary sources and detectors of the on/off type; 4. Effects of interaction on the dynamics of N identical particles in quantum M-mode networks in the dilute regime when N is much less than M. (AU)
