In recent years, action-detected ultrafast spectroscopies have gained popularity offering distinct advantages over their coherently detected counterparts, such as spatially resolved and operando measurements with high sensitivity. However, there are also fundamental limitations connected to the process of signal generation in action-detected experiments. Here we perform fluorescence-detected two-dimensional electronic spectroscopy (F-2DES) of the light-harvesting II (LH2) complex from purple bacteria.

- The study examines the link between childhood maltreatment (CM) reported to authorities and the risk of psychiatric diagnoses by age 30, comparing those with agency-reported CM to the general population.
- Using comprehensive data from birth cohorts in Queensland, Australia, the researchers followed over 83,000 individuals, focusing on psychiatric admissions and types of maltreatment.
- Findings indicate that individuals with agency-reported CM are significantly more likely to receive hospital diagnoses for various psychiatric disorders, especially post-traumatic stress disorder (PTSD), highlighting the importance of early intervention and support for affected individuals.
We present a phase-modulated approach for ultrabroadband Fourier transform electronic spectroscopy. To overcome the bandwidth limitations and spatial chirp introduced by acousto-optic modulators (AOMs), pulses from a 1 µm laser are modulated using AOMs prior to continuum generation. This phase modulation is transferred to the continuum generated in a yttrium aluminum garnet crystal.

- Coherence involves the correlations between waves and is crucial in understanding molecular behaviors in chemistry research.
- The review highlights varying definitions and concepts of "coherence" and "quantum coherence," linking them to interference patterns and their complex nature.
- By clarifying these definitions, the aim is to improve communication and understanding in the diverse field of molecular sciences.
