“…Previous experiments have mainly focused on controlling birefringent effects in the context of linearly polarized light [18,19]. It will be an experimental question whether or not these effects can be sufficiently suppressed as to be a subdominant source of noise.…”

We propose using interferometry of circularly polarized light as a mechanism by which to test for axion dark matter. These interferometers differ from standard interferometers only by the addition of a few quarter wave plates to preserve the polarization of light upon reflection. We show that using current technology, interferometers can probe new regions of axion parameter space up to a couple orders of magnitude beyond current constraints.

“…The effective interactions can in particular impact photon propagation and give rise to remarkable effects such as vacuum birefringence experienced by probe photons traversing a classical electromagnetic field [16][17][18][19]; for ongoing experimental efforts aiming at the verification of vacuum birefringence using macroscopic fields, see [20][21][22][23][24][25]; for theoretical proposals advocating dedicated high-intensity laser experiments, see [26][27][28][29][30][31][32][33][34][35]. Recently, indications have been reported for the relevance of QED vacuum birefringence for optical polarimetry of a neutron star [36].…”

Abstract:We study the effective interactions of external electromagnetic fields induced by fluctuations of virtual particles in the vacuum of quantum electrodynamics. Our main focus is on these interactions at two-loop order. We discuss in detail the emergence of the renowned Heisenberg-Euler effective action from the underlying microscopic theory of quantum electrodynamics, emphasizing its distinction from a standard one-particle irreducible effective action. In our explicit calculations we limit ourselves to constant and slowly varying external fields, allowing us to adopt a locally constant field approximation. One of our main findings is that at two-loop order there is a finite one-particle reducible contribution to the Heisenberg-Euler effective action in constant fields, which was previously assumed to vanish. In addition to their conceptual significance, our results are relevant for high-precision probes of quantum vacuum nonlinearity in strong electromagnetic fields.

“…Presently published results on ∆n (vac) u determined from ellipsometric experiments are reported in Table I. [25] In this letter we report on a significant improvement obtained after the commissioning of the new PVLAS experimental setup installed at the INFN section of Ferrara. The principle of the experiment is explained in [13,16].…”

First results from the new PVLAS apparatus: A new limit on vacuum magnetic birefringence

Several groups are carrying out experiments to observe and measure vacuum magnetic birefringence, predicted by Quantum Electrodynamics (QED). We have started running the new PVLAS apparatus installed in Ferrara, Italy, and have measured a noise floor value for the unitary field magnetic birefringence of vacuum ∆n= (4 ± 20) × 10 −23 T −2 (the error represents a 1σ deviation). This measurement is compatible with zero and hence represents a new limit on vacuum magnetic birefringence deriving from non linear electrodynamics. This result reduces to a factor 50 the gap to be overcome to measure for the first time the value of ∆n (vac,QED) u predicted by QED: ∆n (vac,QED) u = 4 × 10 −24 T −2 . These birefringence measurements also yield improved modelindependent bounds on the coupling constant of axion-like particles to two photons, for masses greater than 1 meV, along with a factor two improvement of the fractional charge limit on millicharged particles (fermions and scalars), including neutrinos.
