Mathematica: Solving Linear Complex Systems

SUMMARY

The discussion focuses on using Mathematica to solve a set of complex linear equations symbolically. The specific problem involves a matrix equation equating two complex matrices, with variables a(p), b(p), c(p), and d(p) dependent on the real constants μ, Re(Δ), Im(Δ), and t. A participant suggests that simplifying the problem by setting sin(p) to zero can facilitate the solution process. The consensus is that the problem is solvable in Mathematica, despite initial difficulties.

Good evening,

I am currently trying to use Mathematica to find the symbolic solutions to a set of complex linear equations. I have never used Mathematica for such a task before and am finding it quite difficult. Let me state the problem:

\begin{pmatrix}a^{*}a-b^{*}b&ac^{*}-bd^{*}\\a^{*}c-b^{*}d&c^{*}c-d^{*}d\end{pmatrix}=\begin{pmatrix}-(\mu+2tcos(p))&2(\Re(\Delta)-i\Im(\Delta))sin(p)\\2(\Re(\Delta)+i\Im(\Delta))sin(p)&\mu+2tcos(p)\end{pmatrix}; \qquad \text{ where } \mu, \Re(\Delta), \Im(\Delta), t \text{ are real constants }; p\inℝ

I am attempting to solve for the complex functions a(p), b(p), c(p), d(p) Is this even possible or am I wasting my time?

Thanks

By inspection, assuming your j(delta) is not equal to zero, that sin(p) is equal to zero.

That substantially simplifies your task, but, like many things in Mathematica, at the moment it is resisting doing something that is simple to describe.
