Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Book Chapter Description
In the ordinary mean field theory, the effective field is static. If one allows temporal variation of the effective field, fluctuation effects of the corresponding field can be included. The correlation problem in a large system is then replaced by a single-site problem surrounded by a dynamical effective medium. The effective impurity system is regarded as zero-dimensional. It can be shown that the replacement by an effective impurity is exact in the limit of large number of neighboring sites, which is the case in infinite dimensions. Hence the zero and infinite dimensions are connected continuously. In this way the dynamical mean field theory (DMFT) approaches actual three-dimensional systems from the infinite-dimensional limit. The DMFT has achieved remarkable success in understanding those many-body effects which come from strong local correlations. This chapter explains the DMFT starting with the background of its development.
