Light propagation in systems involving two-dimensional atomic lattices
Juha Javanainen, Renuka Rajapakse
We study the optical response of a 2D square lattice of atoms using classical electrodynamics. Due to dipole-dipole interactions, the lattice atoms polarize as if the lattice were…
Arrays of strongly-coupled atoms in a one-dimensional waveguide
Janne Ruostekoski, Juha Javanainen
We study the cooperative optical coupling between regularly spaced atoms in a one-dimensional waveguide using decompositions to subradiant and superradiant collective excitation ei…
Exact electrodynamics versus standard optics for a slab of cold dense gas
Juha Javanainen, Janne Ruostekoski, Yi Li +1
We study light propagation through a slab of cold gas using both the standard electrodynamics of polarizable media, and massive atom-by-atom simulations of the electrodynamics. The…
The Software Atom
Juha Javanainen
By putting together an abstract view on quantum mechanics and a quantum-optics picture of the interactions of an atom with light, we develop a corresponding set of C++ classes that…
Collective resonance fluorescence in small and dense atom clouds: Comparison between theory and experiment
S. D. Jenkins, J. Ruostekoski, J. Javanainen +5
We study the emergence of a collective optical response of a cold and dense Rb atomic cloud to a near-resonant low-intensity light when the atom number is gradually increase…
Emergence of correlated optics in one-dimensional waveguides for classical and quantum atomic gases
Janne Ruostekoski, Juha Javanainen
We analyze the emergence of correlated optical phenomena in the transmission of light through a waveguide that confines classical or ultracold quantum degenerate atomic ensembles.…
