update citations to match the linked whitepaper

[djwadhwa]

Description: There are a few inline documentation citations that are not correct. I have used the associated whitepaper links provided to update the citation (including author and year)

Check list:

• New tests are added (if a new feature is added)
• New doc strings: description and/or example code are in RST format
• Documentation is updated (if required)
