Resonances in light scattering from nonequilibrium dipoles pairs

This paper demonstrates that light scattering from pairs of point-like dipoles exhibits exact resonances when the dipoles violate the optical theorem (indicating nonequilibrium or active conditions), leading to potentially infinite scattering amplitudes, while similar but finite resonances in equilibrium systems can still yield significant amplification factors.

Hierarchy of quantum correlations in qubit-qutrit axially symmetric states

This paper investigates quantum correlations in an axially symmetric qubit-qutrit system and establishes a robustness hierarchy where Bell nonlocality is the most fragile, followed by entanglement (Negativity), while Measurement-Induced Non-locality (MIN) and Uncertainty-Induced Nonlocality (UIN) prove to be the most resilient resources against thermal noise and anisotropy.
