Polarimetry for measuring the vacuum magnetic birefringence with quasi-static fields: a systematics study for the VMB@CERN experiment
G. Zavattini, F. Della Valle, A. M Soflau +9
We present an experimental systematics study of the polarimetric method for measuring the vacuum magnetic birefringence based on a pair of rotating half-wave plates. The presence o…
The PVLAS experiment: a 25 year effort to measure vacuum magnetic birefringence
A. Ejlli, F. Della Valle, U. Gastaldi +4
This paper describes the 25 year effort to measure vacuum magnetic birefringence and dichroism with the PVLAS experiment. The experiment went through two main phases: the first usi…
Polarisation dynamics of a birefringent Fabry-Perot cavity
Aldo Ejlli, Federico Della Valle, Guido Zavattini
Optical Fabry-Perot cavities always show a non-degeneracy of two orthogonal polarisation states. This is due to the unavoidable birefringence of dielectric mirrors whose effects ar…
A polarisation modulation scheme for measuring vacuum magnetic birefringence with static fields
G. Zavattini, F. Della Valle, A. Ejlli +1
A novel polarisation modulation scheme for polarimeters based on Fabry-Perot cavities is presented. The application to the proposed HERA-X experiment aiming to measuring the magnet…
The PVLAS experiment: measuring vacuum magnetic birefringence and dichroism with a birefringent Fabry-Perot cavity
F. Della Valle, E. Milotti, A. Ejlli +5
Vacuum magnetic birefringence was predicted long time ago and is still lacking a direct experimental confirmation. Several experimental efforts are striving to reach this goal, and…
New PVLAS model independent limit for the axion coupling to for axion masses above 1meV
F. Della Valle, A. Ejlli, U. Gastaldi +6
During 2014 the PVLAS experiment has started data taking with a new apparatus installed at the INFN Section of Ferrara, Italy. The main target of the experiment is the observation…
First results from the new PVLAS apparatus: a new limit on vacuum magnetic birefringence
F. Della Valle, E. Milotti, A. Ejlli +6
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…
Measurement of the Cotton Mouton effect of water vapour
F. Della Valle, A. Ejlli, U. Gastaldi +6
In this paper we report on a measurement of the Cotton Mouton effect of water vapour. Measurement performed at room temperature ( K) with a wavelength of 1064 nm gave the va…
Measurements of vacuum magnetic birefringence using permanent dipole magnets: the PVLAS experiment
F. Della Valle, U. Gastaldi, G. Messineo +5
The PVLAS collaboration is presently assembling a new apparatus (at the INFN section of Ferrara, Italy) to detect vacuum magnetic birefringence (VMB). VMB is related to the structu…
Measuring the magnetic birefringence of vacuum: the PVLAS experiment
Guido Zavattini, Ugo Gastaldi, Ruggero Pengo +3
We describe the principle and the status of the PVLAS experiment which is presently running at the INFN section of Ferrara, Italy, to detect the magnetic birefringence of vacuum. T…
Testing the neutrality of matter by acoustic means in a spherical resonator
G. Bressi, G. Carugno, F. Della Valle +3
New measurements to test the neutrality of matter by acoustic means are reported. The apparatus is based on a spherical capacitor filled with gaseous SF excited by an oscillati…
Towards a direct measurement of vacuum magnetic birefringence: PVLAS achievements
F. Della Valle, G. Di Domenico, U. Gastaldi +4
Nonlinear effects in vacuum have been predicted but never observed yet directly. The PVLAS collaboration has long been working on an apparatus aimed at detecting such effects by me…
Frequency locking to a high-finesse Fabry-Perot cavity of a Frequency doubled Nd:YAG laser used as the optical phase modulator
M. Bregant, G. Cantatore, F. Della Valle +2
We report on the frequency locking of a frequency doubled Nd:YAG laser to a 45 000 finesse, 87-cm-long, Fabry-Perot cavity using a modified form of the Pound-Drever-Hall technique.…
Optical production and detection of dark matter candidates
F. Brandi, M. Bregant, G. Cantatore +11
The PVLAS collaboration is at present running, at the Laboratori Nazionali di Legnaro of I.N.F.N., Padova, Italy, a very sensitive optical ellipsometer capable of measuring the sma…
