Schrodinger’s time dependent equation (H (t) = - i (h/2 ) d( (t))/dt) Allows us to solve for dc j /dt, d/dt (c j c k *) = c j (dc k */dt) + (dc j /dt) c … Web22), a diagonal matrix. Density is “random” in the x-y plane. When take a slice parallel to x-y, you get a circle. When r = .75, Σ is not a diagonal . Density is not random in x-y plane. There is a linear tilt (ie., density is concentrated on a line). When you take a slice you get an ellipse that’s tilted.
