That is a complex question. A complex number is anything that is the square root of a negative number. These are most prominent and useful in quantum physics. What do you mean by system?

A complex number is generally the addition of a real number and an imaginary number. An imaginary number is the square root of a negative real number, and the square root of -1 is called i. A complex number c takes the general form: c = a + bi Complex numbers are usually plotted on a 2D graph with the horizontal axis representing real numbers and the vertical axis representing imaginary numbers. So, the complex number c has the coordinates (a,b). If you represent the complex number in circular coordinates, where r=sqrt(a^2+b^2) is the vector magnitude and t=atan(b/a) is the angle, you get a really nice result: c = r*e^(it) = r*cos(t) + i*r*sin(t) And thats just the start...
