"The Sagnac effect in General Relativity"


     címmel tartandó szemináriumára.


Kivonat:



The Sagnac effect can be described as the difference in travel time 
between two photons traveling along the same path in opposite 
directions. In this talk we explore the consequences of this 
characterisation in the context of General Relativity. We derive a 
general expression for this time difference in an arbitrary space-time 
for arbitrary paths. In general, this formula is not very useful since 
it involves solving a differential equation along the path. However, we 
also present special cases where a closed form expression for the time 
difference can be given. We discuss the effect in a small neighbourhood 
of an arbitrarily moving observer in their arbitrarily rotating 
reference frame. We may also discuss the special case of stationary 
space-times and point out the relationship between the Sagnac effect and 
Fizeau's `aether-drag' experiment.
