We challenge the misconception that Bloch-Redfield equations are a less powerful tool than phenomenological Lindblad equations for modeling exciton transport in photosynthetic complexes. This view predominantly originates from an indiscriminate use of the secular approximation. We provide a detailed description of how to model both coherent oscillations and(More)

Organizations pursuing development of their competences must balance the pursuit of mastery in the present against the potential of innovations that may enable success in the future. In the present, key competences can be identified as work practices essential to the satisfaction of customers and other stakeholders. These competences may be improved(More)
We investigate how correlated fluctuations affect oscillatory features in rephasing and non-rephasing two-dimensional (2D) electronic spectra of a model dimer system. Based on a beating map analysis, we show that non-secular environmental couplings induced by uncorrelated fluctuations lead to oscillations centered at both cross- and diagonal-peaks in(More)

The development of modern, highly interactive AJAX Web applications that enable dynamic visualization of data requires writing a great deal of tedious "plumbing code" to interface data between browser-based DOM and AJAX components, the application server, and the SQL database. Worse, each of these layers utilizes a different language. Further, much code is(More)
