Nonmonotonic field dependence of damping and reappearance of Rabi oscillations in quantum dots.
TLDR
It is found that the phonon-induced damping of Rabi rotations is a nonmonotonic function of the laser field that is increasing at low fields and decreasing at high fields, which results in a reappearance of RBI rotations at high field.

Extended Ginzburg-Landau formalism for two-band superconductors.
TLDR
The extended version of the two-band Ginzburg-Landau GL formalism improves the validity of GL theory below T(c) and suggests revisiting the earlier calculations based on the standard model.
