Practical witness for electronic coherences.

The origin of the coherences in two-dimensional spectroscopy of photosynthetic complexes remains disputed. Recently, it has been shown that in the ultrashort-pulse limit, oscillations in a frequency-integrated pump-probe signal correspond exclusively to electronic coherences, and thus such experiments can be used to form a test for electronic vs. vibrational oscillations in such systems. Here, ...

Disentangling electronic and vibronic coherences in two-dimensional echo spectra.

The prevalence of long-lasting oscillatory signals in two-dimensional (2D) echo spectroscopy of light-harvesting complexes has led to a search for possible mechanisms. We investigate how two causes of oscillatory signals are intertwined: (i) electronic coherences supporting delocalized wavelike motion and (ii) narrow bands in the vibronic spectral density. To disentangle the vibronic and electr...

Resolving Vibrational from Electronic Coherences in Two-Dimensional Electronic Spectroscopy: The Role of the Laser Spectrum.

The observation of coherent quantum effects in photosynthetic light-harvesting complexes prompted the question whether quantum coherence could be exploited to improve the efficiency in new energy materials. The detailed characterization of coherent effects relies on sensitive methods such as two-dimensional electronic spectroscopy (2D-ES). However, the interpretation of the results produced by ...

Should relatives witness resuscitation? Ethical issues and practical considerations.

In winning second prize in the Logie Medical Ethics Essay Contest in 1997, Carolyn Rosenczweig raised questions about the role patients' family members should be allowed to play during resuscitative efforts by medical staff. She concluded that even though their presence might complicate resuscitation attempts, "blanket policies that exclude all relatives from being present seem a knee-jerk reac...
