pydmqmc.utils.integer_to_bitarray(iba, norb)

Generate a bitarray given an integer representation.

Parameters:

ibaint

The integer representation of the bitarray.

norbint

The total number of spin-orbitals for the system.

Returns:

array

The array of integer bits representing the determinant.

Notes

A bitarray is shorthand for an array of 1’s and 0’s. More traditionally referred to as “bitstrings,” these are used to represent Slater determinants.
