Hi everyone,
          Question: Is there any systematic way to decompose the first-order
 density matirx in real space? Apparently people use the localized
 nature of density matrix as in insulators or use the so called 'divide and
 conquer' approach to divide it. I guess it would be very hard if not impossible
 to find a systematic way to decompose it for any system. But any suggestion,
 reference will be highly appreciated
