Thanks. I have always had the same view that the coupling of the electric field to spin would be very small hence negligible. Recently I came across an article discussing the effects of an electric field on spin wave dispersion relation in multiferriocs.(doi:10.4236/wjcmp.2012.24037 Published...
Hi PF members. I have got a little worry
I am familiar with the Zeeman term that always appears in the Hamiltonian of a spin chain representing the influence of an external magnetic field. I don't know if there is a similar term if the spin was rather in he presence of an electric field ( I...
Well I'm just very curious about the giant experiment which is to be tested this month about the one superstring .I have studied quantum mech. but not the string theory so I don't seem to understand what its all about so could some one just brief me on string theory
