We investigate, both theoretically and experimentally, the phenomenon of polarization rotation of a weak, linearly-polarized optical (probe) field in an atomic system with multiple three-level electromagnetically induced transparency (EIT) sub-systems. The polarization rotation angle can be controlled by a circularly-polarized coupling beam, which breaks the symmetry in number of EIT subsystems...

Calibrating the strength of light-matter interaction is an important experimental task in quantum information and state engineering protocols. The off-resonant multi-atom spin oscillators can be characterized by readout rate Γ S . Here we introduce method named Coherently Induced FAraday Rotation (CIFAR) for determining rate. suited both continuous pulsed oscillator, relying only on applying a ...

We examine the generation of a magnetic field in a solar-like star and its effects on the internal distribution of the angular velocity. We suggest that the evolution of a rotating star with magnetic fields leads to an equilibrium value of the differential rotation. This equilibrium is determined by the magnetic coupling, which favours a constant rotation profile, and meridional circulation whi...
