How I got to work with Feynman on the covariant quark model
Finn Ravndal
In the period 1968 - 1974 I was a graduate student and then a postdoc at Caltech and was involved with the developments of the quark and parton models. Most of this time I worked i…
Oskar Klein and the fifth dimension
Finn Ravndal
After a short biographical summary of the scientific life of Oskar Klein, a more detailed and hopefully didactic presentation of his derivation of the relativistic Klein-Gordon wav…
Symmetric and conserved energy-momentum tensors in moving media
Finn Ravndal
A symmetric and conserved energy-momentum tensor for a scalar field in a moving medium is derived using the Gordon metric. When applied to an electromagnetic field, the method give…
A dispersive correction to the Casimir force
Finn Ravndal, Lee-Peng Teo
Using perturbation theory the first order dispersive correction to the Casimir energy between two plates separated by a dielectric material is calculated. It falls off with the pla…
On the Casimir effect in a continuous medium
Finn Ravndal
It is pointed out that the Casimir energy in a medium can be obtained most directly from the zero-point energy of the electromagnetic field because of its reduced propagation veloc…
Electromagnetism and photons in continuous media
Finn Ravndal
Different theoretical and experimental aspects of electromagnetic phenomena in media is reviewed. The 100 year old Minkowski theory is in agreement with most experiments, but has t…
