Researchers publish review article on the physics of interacting particles

#Scientific articles in the field of physics are mostly very short and deal with a very restricted topic. A remarkable exception to this is an article published recently by physicists from the #Universities of Münster and Düsseldorf. The article is 127 pages long, cites a total of 1075 sources and deals with a wide range of branches of physics—from biophysics to quantum mechanics.

The article is a so-called review article and was written by physicists #Michael te #Vrugt and #Prof. #Raphael #Wittkowski from the #Institute of Theoretical #Physics and the #Center for #Soft #Nanoscience at the #University of Münster, together with #Prof. #Hartmut Löwen from the #Institute for Theoretical #Physics II at the #University of Düsseldorf. The aim of such review articles is to provide an introduction to a certain subject area and to summarize and evaluate the current state of research in this area for the benefit of other researchers. “#In our case we deal with a theory used in very many areas—the so-called dynamical density functional theory (DDFT),” explains last author #Raphael #Wittkowski. “#Since we deal with all aspects of the subject, the article turned out to be very long and wide-ranging.”

DDFT is a method for describing systems consisting of a large number of interacting particles such as are found in liquids, for example. #Understanding these systems is important in numerous fields of research such as chemistry, solid state physics or biophysics. #This in turn leads to a large variety of applications for DDFT, for example in materials science and biology. “DDFT and related methods have been developed and applied by a number of researchers in a variety of contexts,” says lead author #Michael te #Vrugt. “#We investigated which approaches there are and how they are connected—and for this purpose we needed to do a lot of work acting as historians and detectives,” he adds.

The article has been published in the journal #Advances in #Physics, which has an impact factor of 30.91—making it the most important journal in the field of condensed matter physics. #It only publishes four to six articles per year. The first article on DDFT, written by #Robert #Evans, was also published in #Advances in #Physics, in 1979. “#This makes it especially gratifying that our review has also been published in this journal,” says secondary author #Hartmut Löwen. “#It deals with all the important theoretical aspects and fields of application of DDFT and will probably become a standard work in our field of research.”
