Performance of a Sagnac interferometer to observe vacuum optical nonlinearity
Aurélie Max Mailliet, Adrien E. Kraych, François Couchot +8
In Quantum Electrodynamics, vacuum becomes a nonlinear optical medium: its optical index should be modified in the presence of intense external electromagnetic fields. The DeLLight…
