I wish to do DFT calculations and use the frozen phonon approach via Phonopy. Should I pay attention to the magnetic moments?
Sometimes, individual atoms in a crystal have different magnetic moments. Does this have any additional effect?
Hi Hitanshu Sachania :
Correct me if I'am wrong but, I don't think the magnetic moment of phonons could be a relevant part in the dispersion relations, or in another properties of phonons, like its density of states, etc...
Phonons, if the have a magnetic moment, this should be very tiny, since Phonons are quasiparticles of zero spin.
Regards !
Dear P. Contreras :
But the transverse modes also have spin=0 . Or am I wrong ?
In my view of classical particle physics, for a particle to have Magnetic Moment, this should have some quantity of spin, or some intrinsic angular momentum,
... But not sure of the right answer.
Kind Regards !
Hello Franklin Uriel Parás Hernández and P. Contreras, thank you for your replies. I apologise for not being clear earlier but I meant to ask if the electronic magnetic moment will have a (profound) effect on the phonon band structure or density of states?
I see Hitanshu Sachania , yep that is something different, no worries.
I don't think so, since phonons doesn't have electric charge nor magnetic moment.
Dear P. Contreras :
Photons does n't have electric charge , and yes they do have spin.
They have a spin equals to 1 and this is why they are bosonic particles.
Regards ! :)
Dear P. Contreras
The transverse modes does n't have intrinsic angular momentum neither.
To tell the truth, I don't know the reason why this is.
Regards !
Dear P. Contreras :
Phononics is the field of nanotechnology about trying to implement (phononic) devices in circuits like computer chips, power circuits, sensors , etc. But these devices instead of giving up a signal driven by the flow of electrons, they do so driven by the flow of heat.
Normally with these devices we are interesting in Heat Fluxes and charge transport at the nanoscale.
Phononics, we can say; is the analogy of electronics but with Heat, instead of Charge Transport.
Devices as the Thermal Diode (or thermal rectifier) , the Thermal Transistor, etc ...
Regards !
