Quantum Mechanics and Applications

We consider a physical process that leads to the generation of atomic Schr\"odinger cat states for a system of two level atoms. The effective interaction between atoms in a dispersive cavity leads to the superposition of atomic coherent states. We study in detail the quasidistributions for these states and demonstrate how the Schr\"odinger cat states can lead to interesting interferences over the surface of a sphere.
