| May 1, 2023 at 4:50 | comment | added | Michael Engelhardt | I also find the characterization of the mean field approximation as describing collective dynamics questionable. Isn't the whole point of the approximation that one continues to treat the individual particle as an appropriate degree of freedom rather than passing to collective degrees of freedom? | |
| May 1, 2023 at 4:48 | comment | added | Michael Engelhardt | There seems to be an implicit premise in this post that the mean field approximation becomes accurate for large systems. That is usually not the case. Since this approximation truncates correlations, its appropriateness critically depends on the type and strength of interactions rather than on system size, and has to be assessed case by case. | |
