1. Experimental limit on Spontaneous Parametric Up Conversion

Abstract

We present a first experimental test of the existence of Spontaneus Parametric Up Conversion, predicted by a specific local realistic model based on Wigner function formalism. The measurement has been made using a ccd camera on the emission of a LiIO3 crystal pumped by a 351 nm and/or a 789 (1064) nm lasers. We obtain an upper limit of 160 times on the ratio between intensity of Spontaneus Parametric Up Conversion and Spontaneous Parametric Down conversion.

Abstract

We discuss if experimental tests of Bell inequalities performed with pseudoscalar mesons (K or B) can be definitive. Our conclusion is that this is not the case, for the efficiency loophole cannot be eliminated., submitted for publication

3. First experimental test of Bell inequalities performed using a non-maximally entangled state

Abstract

We report on the realisation of a new test of Bell inequalities using the superposition of type I parametric down conversion produced in two different non-linear crystals pumped by the same laser, but with different polarisation. The produced state is non-maximally entangled. We discuss the advantages and the possible developments of this configuration.

4. Quantum non-demolition (QND) modulation of quantum interference

Author

M. Genovese and C. Novero

Subjects
Physics, Interferometry, Quantum Physics, Modulation, Realisation, Quantum mechanics, Quantum interference, FOS: Physical sciences, Quantum Physics (quant-ph), Quantum, Atomic and Molecular Physics, and Optics, Optics (physics.optics), Physics - Optics
Abstract

We propose an experiment where quantum interference between two different paths is modulated by means of a QND measurement on one or both the arm of the interferometer. The QND measurement is achieved in a Kerr cell. We illustrate a scheme for the realisation of this experiment and some further developments., accepted for publication

9. Isotopic shift measurements of the (3)S(3sns)-(3)P(3s3p) transitions of Mg I.

Author

Novero C and Godone A

Abstract

We have measured the isotopic shifts of the (3)S(3s6s)-(3)P(3s3p) and (3)S(3s7s)-(3)P(3s3p) transitions of Mg I and the values of the hyperfine-structure constant A((3)S(1)) for the 3s6s and 3s7s terms of (25)Mg. The absolute wavelengths have been measured at an accuracy level of +/-3 x 10(-7), mainly limited by the Doppler broadening of the I(2) transitions used as a reference and by the precision of the knowledge of the related wavelengths. The measurements have been performed in an atomic beam rich in metastable atoms by scanning a ring dye laser and observing simultaneously the fluorescence of the beam.

10. Evidence for laser cooling in a magnesium atomic beam.

Author

Beverini N, De Pascalis S, Maccioni E, Pereira D, Strumia F, Vissani G, Wang YZ, and Novero C

Abstract

Laser cooling in a Mg atomic beam is reported for the first time to our knowledge. Previous cooling experiments were performed by using visible or infrared lasers. The Mg atoms were cooled by using an intracavity frequency-doubled dye laser at 285 nm to reach the resonant (1)S(0)-(1)P(1) transition. Evidence of laser cooling was obtained even with the limited available laser power ( approximately 1-2 mW).
