The EPR Paradox and Bell’s Theorem are two related concepts in quantum mechanics that deal with the idea of entanglement. In the EPR Paradox, two particles are considered to be “entangled” if the state of one particle can be determined by measuring the state of the other particle, even if the two particles are separated by a large distance. This is a violation of the traditional notion of “local realism”, where each particle has its own independent state.

Bell’s Theorem is an extension of the EPR Paradox that states that when two particles are entangled, any measurement performed on one particle will affect the measurement performed on the other particle, regardless of the distance between them. This theorem has since been confirmed by numerous experiments and is considered to be one of the foundations of quantum mechanics.

 

When an atom interacts with a bounded electromagnetic field, some of the radiative properties of the atom will differ in contrast to that in free space. The field of physics that studies bounded interaction is cavity quantum electrodynamics (Cavity QED). This seminar will give an introduction to perturbative cavity QED by studying atom-photon system in free space, and when the system is bounded by mirrors. It will illustrate the effects on spontaneous radiation and energy level shift (Lamb shift).

All faculty, researchers and students are invited to attend.
