In summary, Special Relativity introduced the concept of spacetime as a continuum and an invariant interval to explain how the same event can be perceived differently by different observers depending on their frame of reference. The formula s^2=dx^2-dct^2 represents this concept and shows ...

Moreover, in this limit, much like the spectral dimension, the density of state parameter is not well defined, which again reinforces the fact that this approximate method of adding a zero-point length to the geodesic interval works only in the mesoscopic region near the Planck scale and at...
The response of the Unruh-DeWitt type monopole detectors which were coupledto the quantum field only for a finite proper time interval is studied forinertial and accelerated trajectories, in the Minkowski vacuum in (3+1)dimensions. Such a detector will respond even while on an inertial trajctory...
LetAandBbe two points (i.e. events) in spacetime, and letVbe the displacement vector,V:=B−A. IfVis spacelike, we define thechord lengthto be √V·V, which is also called theinvariant spatial interval. If on the other handVis timelike, we define thechord timeto be √−V·V, ...
Now, if the interval of time that S embraces is large enough so as to explore the minimum frequency in the spectrum (now we can really call ωn[t˜] a frequency), then it is clear that we can talk about the modes (17) as forming an orthonormal basis of modes with well-defined ...
the observation event pO on the worldline γO of the observer with the emission event pS on the worldline γS of the light source, one considers a neighboring lightlike geodesic that meets γO at a proper time interval ΔτO from pO and γS at a proper time interval ΔτS from pS. ...
