The key electronic and phononic processes governing hot carrier cooling dynamics in perovskite nanosystems can be tuned through Pb-Sn alloying.

This work demonstrates versatile light manipulation of various excitons in WSe₂ via contrasting exciton-photon coupling with dipole-orientation, diffusion and chirality dependences.

Combining photoacoustic excitation with optomechanics enables the mechanical modes associated with entire microorganisms to be detected, demonstrating that mechanical spectroscopy allows us to identify microorganisms and characterize their life stages.

Event-based detectors, which respond to local changes in light intensity rather than producing images, enable super-resolution single-molecule localization microscopy with sensitivity and resolution comparable to conventional methods.
