Cavity-free photon blockade induced by many-body bound states.
Abstract
The manipulation of individual, mobile quanta is a key goal of quantum communication;
to achieve this, nonlinear phenomena in open systems can play a critical role. We
show theoretically that a variety of strong quantum nonlinear phenomena occur in a
completely open one-dimensional waveguide coupled to an N-type four-level system.
We focus on photon blockade and the creation of single-photon states in the absence
of a cavity. Many-body bound states appear due to the strong photon-photon correlation
mediated by the four-level system. These bound states cause photon blockade, which
can generate a sub-Poissonian single-photon source.

Harold U. Baranger
Professor of Physics
The broad focus of Prof. Baranger's group is quantum open systems at the nanoscale,
particularly the generation of correlation between particles in such systems. Fundamental
interest in nanophysics-- the physics of small, nanometer scale, bits of solid-- stems
from the ability to control and probe systems on length scales larger than atoms but
small enough that the averaging inherent in bulk properties has not yet occurred.
Using this ability, entirely unanticipated phenomena ca
Daniel J. Gauthier
Research Professor of Physics
Prof. Gauthier is interested in a broad range of topics in the fields of nonlinear
and quantum optics, and nonlinear dynamical systems.
In the area of optical physics, his group is studying the fundamental characteristics
of highly nonlinear light-matter interactions at both the classical and quantum levels
and is using this understanding to develop practical devices.
At the quantum level, his group has three major efforts in the area of quantum communication
and networking. I
