Propagators are powerful theoretical tools that were first developed within the nonrelativistic (NR) regime and were applied to calculate atomic and molecular properties more than 30 years ago. The recent relativistic ...

Electromagnetic waves propagation on either rotating or anisotropic spacetime backgrounds (such as Kerr and Godel metrics, or Bianchi-I metric) produce a reduction of the magnitude of Casimir forces between plates. These ...

This Letter proposes a new optical architecture based on a double-sideband filter, simultaneously applied at the Fourier plane, for inline digital holography. The proposed architecture not only allows removal of the conjugate ...

The pulsed electric acoustic technique, PEA, have been usually applied to probe space charge profiles in polymers. In this work we show preliminary results obtained with lead zirconate-titanate and niobium, PZTN, ferroelectric ...
