TL;DR: A vibrational spectroscopy technique that measures the electric field emitted from organic molecules following infrared illumination allows their molecular fingerprints to be separated from the excitation background, even in complex biological samples, and promises improved molecular sensitivity and molecular coverage for probing complex, real-world biological and medical settings.

TL;DR: In this article, the authors investigate the strain-induced coupling between a nitrogen-vacancy impurity and a resonant vibrational mode of a diamond nanoresonator and derive a semiclassical model to describe the stationary state of the resonator mode under various driving conditions.

TL;DR: In this article, a new type of symmetry breaking, which occurs in the steady-state energy distribution of open systems with balanced gain and loss, is described, where the combination of nonlinear saturation effects and the presence of thermal or quantum noise in actual experiments results in unexpected behavior that differs significantly from the usual dynamical picture.

TL;DR: In this paper, a diamond beam bending above a magnetic tip is considered, where the defect experiences a varying magnetic field which may flip its spin by absorbing mechanical energy from the low-frequency flexural motion of the beam.
