Exotic atoms

In this paper I review a number of recent results in the field of exotic atoms. Recent experiments or ongoing experiments with muonic, pionic and antiprotonic hydrogen, as well as recent measurement of the pion mass are described. These experiments provide information about nucleon-pion or nucleonantinucleon interaction as well as information on the proton structure (charge or magnetic moment d...

Exotic superfluidity in cold atoms

We derived the low energy effective action for the collective modes in asymmetric fermionic systems with attractive interaction. We obtained the phase diagram in terms of the chemical potentials. It features a stable gapless superfluidity with one Fermi surface on the BEC side of the resonance. Also we predict a sharp increase in outer core of a vortex, i.e. vortex size, upon entering into the ...

Travelling to exotic places with ultracold atoms

We review and speculate on two recent developments of quantum optics and ultracold atoms. First, we discuss a possible realization of “phonon” physics, or as we call it refracton physics with optical lattices. To this aim we combine the physics of cold atoms with cavity QED, and investigate superfluid – Mott insulator quantum phase transition. The systems can exhibit cavity mode modifications d...

Scattering of light exotic atoms in excited states

The differential and total cross sections for the scattering of muonic, pionic, kaonic and antipro-tonic hydrogen in excited states from atomic hydrogen have been calculated for the purpose of atomic cascade calculations. The scattering problem is treated in a fully quantum mechanical framework which takes the energy shifts and, in the case of the hadronic atoms, the widths of the ns states int...
