I want to find the Abs square of this complex expression.
I tried using Abs command and then squaring it but nothing happened, it just showed 'Abs' in the output. I also tried multiplying it with its conjugate but to no avail.
I think the problem is that it doesn't know which terms are complex and which are real. Here everything is real except the Iota part of course.
I do not know how to specify others as real or find its Absolute value in general. May anyone suggest something?
