Most taxpayers now qualify for the standard deduction, but there are some important details involving itemized deductions that people should keep in mind. WebMay 11, 2024 · Mean-field theory approximates the effect of the environment on any given individual degree of freedom by a single, averaged effect, and thus reduces a many-body problem to an (effective) one-body problem. This is a drastic approximation.
