Hello,
In most of the papers like
http://eprints.qut.edu.au/4763/1/4763.pdf
one sees the raman spectra of crystals or molecules and the peaks are not further described (if they are stokes or antistokes). Do all the Peaks belong to the Anti-stokes-lines? And if it is so, why don't we see any...
No, i just assume that the magnetization is small enough in the normal state, because the sample is not diamagnetic in normal state. The diamagnetism is only seen in the superconducting state with $$M=H,$$ and hence can not be assumed to be small enough to be neglected
Hello,
I consider an ideal superconductor with the gibbs-energy $$ d G=-SdT + VdP - \mu_0 M V dH$$
and helmholtz energy $$ dF = -SdT -P dV + \mu_0 V H dM$$
Assuming, that in the normal state the magnetization is too small, so that G_n(H) = G_n(H=0) and at the transition point H_c the...
The question is to show, that if \phi solves the equation {1\over{c^2}} {\partial^2 ( r \phi) \over{\partial t^2}} = {\partial^2 (r \phi) \over{\partial r^2}}
than so should every partial derivative $$\frac{\partial\phi}{\partial x }, \frac{\partial\phi}{\partial y }...
I would like to show, that if \phi is a solution to the equation than each partial derivative of \phi is also a solution.
I am failing to show that just by plugging the derivative in. How can i do that?
Hello!
The wave equation given: {1\over{c^2}} {\partial^2 \phi\over{\partial t^2}} = \Delta \phi with r = \sqrt{x^2+y^2+z^2} needs to be rearranged, so that {1\over{c^2}} {\partial^2 ( r \phi) \over{\partial t^2}} = {\partial^2 (r \phi) \over{\partial r^2}} .
Are there any tricks to obtain...
