CMB Polarization Systematics, Cosmological Birefringence and the Gravitational Waves Background
Luca Pagano, Paolo de Bernardis, Grazia De Troia +6
Cosmic Microwave Background experiments must achieve very accurate calibration of their polarization reference frame to avoid biasing the cosmological parameters. In particular, a…
A Constraint on Planck-scale Modifications to Electrodynamics with CMB polarization data
Giulia Gubitosi, Luca Pagano, Giovanni Amelino-Camelia +2
We show that the Cosmic Microwave Background (CMB) polarization data gathered by the BOOMERanG 2003 flight and WMAP provide an opportunity to investigate {\it in-vacuo} birefringen…
Discreteness of area in noncommutative space
Giovanni Amelino-Camelia, Giulia Gubitosi, Flavio Mercati
We introduce an area operator for the Moyal noncommutative plane. We find that the spectrum is discrete, but, contrary to the expectation formulated by other authors, not character…
On the distance observable in the Moyal plane and in a novel two-dimensional space with string-theory pregeometry
Giovanni Amelino-Camelia, Giulia Gubitosi, Flavio Mercati
Motivation for the study of spacetime noncommutativity comes primarily from its possible use in investigations of (Planck-scale) spacetime fuzziness, but most work focuses on S-mat…
A no-pure-boost uncertainty principle from spacetime noncommutativity
Giovanni Amelino-Camelia, Giulia Gubitosi, Antonino Marcianó +2
We study boost and space-rotation transformations in kappa-Minkowski noncommutative spacetime, using the techniques that some of us had previously developed (hep-th/0607221) for a…
