Abstract
Optical traps are useful for micro- and nano-scale manipulation of a wide range of objects. Our modeling of the forces on an object within an optical trap aims to implement the Maxwell stress tensor formalism, via numerical computational methods. There are a number of choices to be made in implementing such an approach. We plan to highlight choices that are well suited to assessing the degree to which the electromagnetic forces are conservative, for a given experimental situation, which can prove useful for assessing thermodynamic tests.
