Test of some Fundamental Principles in Physics via Quantum Interference with Neutrons and Photons

Understand

The limitations and possibilities that the concept of quantum interference offers as a tool for testing fundamental physics are explored here.

• The use of neutron interference as an instrument to confront against measurement readouts some of the principles behind metric theories of gravity will be analyzed, as well as some discrepancies between theory and experiment.
• The main restrictions that this model embodies for the study of some of the features of the structure of space--time will be explicitly pointed out.
• For instance, the conditions imposed by the necessary use of the semiclassical approximation.
