Talk:Bloch equations

Clockwise vs. Counterclockwise
Actually, Mxy rotates in clockwise direction:

$$e^{-i\varphi} = \cos\varphi - \sin\varphi$$

When $$\varphi$$ grows, the apex of the Mxy moves down and to the left -- clockwise.

Moreover, I think that writing $$\omega_0 = -\gamma B_0$$ would be somewhat better because it is easier to draw the parallel with the notion of Larmor frequency in this way.

I will only change "counterclockwise" to "clockwise" and wait for comments on the negative circular frequency idea.

bloch-equation quantum theory
the block-equation, or rather a bloch-action that induces the (plain) bloch equation, also arises in quantum field theory, when constructing a feynman path integral (euklidean) for spin degrees of freedom [condensed matter field theory, altland/simons, 3.3.5]. this might be interesting fact to add. 217.93.151.103 (talk) 13:50, 4 May 2011 (UTC)

Bz and the change of Mz
According to the equation, Bz does not directly affect the change of Mz, this is very weird. Jackzhp (talk) 17:18, 9 November 2013 (UTC)
