Should I bring work samples to an interview?

Let’s say I have an interview with a financial company that helps issue bonds. I have some knowledge of bonds. Should I bring work samples, such as interest rate sensitivity analyses or bond valuations, to the interview? If so, when would be an appropriate time for me to show the work samples? If not, how else could I demonstrate my skills in working with bonds aside from simply stating that I have skills?

By the way, let’s assume that the company has no set requirement on work samples. They do not even mention work samples in the interview invitation.
