• Abstract summary: We observe how a focused laser beam can shift by hundreds-time their natural linewidth at the single molecule scale. Results are interpreted as effects of a photo-ionization cascade, leading to a stable electric field. System enables fabrication-free, independent tuning of multiple molecules integrated on the same photonic chip.

• Abstract: The local interaction of charges and light in organic solids is the basis of distinct and fundamental effects. We here observe, at the single molecule scale, how a focused laser beam can locally shift by hundreds-time their natural linewidth and in a persistent way the transition frequency of organic chromophores, cooled at liquid helium temperatures in different host matrices. Supported by quantum chemistry calculations, the results are interpreted as effects of a photo-ionization cascade, leading to a stable electric field, which Stark-shifts the molecular electronic levels. The experimental method is then applied to a common challenge in quantum photonics, i.e. the independent tuning and synchronization of close-by quantum emitters, which is desirable for multi-photon experiments. Five molecules that are spatially separated by about 50 microns and originally 20 GHz apart are brought into resonance within twice their linewidth. Combining this ability with an emission linewidth that is only limited by the spontaneous decay, the system enables fabrication-free, independent tuning of multiple molecules integrated on the same photonic chip.

  coherent control of a two-level system is among the most essential challenges in modern quantum optics. We use a mechanically isolated quantum emitter in hexagonal boron nitride to explore the individual mechanisms which affect the coherence of an optical transition under resonant drive. New insights on the underlying physical decoherence mechanisms reveals a limit in temperature until which coherent driving of the system is possible.

  Quantum coherence between electronic states of a photoionized molecule and the resulting process of ultrafast electron-hole migration has been put forward as a possible quantum mechanism of charge-directed reactivity governing the photoionization-induced molecular decomposition. Here, we use x-rays both to create and to directly probe quantum coherence in the photoionized amino acid glycine. Delayed x-ray pulses track the induced coherence through resonant x-ray absorption that induces Auger decay and by the photoelectron emission from sequential double photoionization.
