Multimode Trapped Interferometer with Ideal Bose-Einstein Condensates
Leonardo Masi, Tommaso Petrucciani, Alessia Burchianti +8
We experimentally demonstrate a multi-mode interferometer comprising a Bose-Einstein condensate of K atoms trapped in a harmonic potential, where the interatomic interaction…
Effect of interactions in the interference pattern of Bose Einstein condensates
A. Burchianti, C. D'Errico, L. Marconi +3
Understanding the effect of interactions in the phase evolution of expanding atomic Bose Einstein condensates is fundamental to describe the basic phenomenon of matter wave interfe…
Quantum nondemolition measurement of optical field fluctuations by optomechanical interaction
A. Pontin, M. Bonaldi, A. Borrielli +7
According to quantum mechanics, if we keep observing a continuous variable we generally disturb its evolution. For a class of observables, however, it is possible to implement a so…
Control of Recoil Losses in Nanomechanical SiN Membrane Resonators
A. Borrielli, L. Marconi, F. Marin +8
In the context of a recoil damping analysis, we have designed and produced a membrane resonator equipped with a specific on-chip structure working as a "loss shield" for a circular…
Microfabrication of large area high-stress silicon nitride membranes for optomechanical devices
E. Serra, M. Bawaj, A. Borrielli +16
In view of the integration of membrane resonators with more complex MEMS structures, we developed a general fabrication procedure for circular shape SiN membranes using Deep Re…
Dynamical two-mode squeezing of thermal fluctuations in a cavity opto-mechanical system
A. Pontin, M. Bonaldi, A. Borrielli +7
We report the experimental observation of two-mode squeezing in the oscillation quadratures of a thermal micro-oscillator. This effect is obtained by parametric modulation of the o…
Probing deformed commutators with macroscopic harmonic oscillators
Mateusz Bawaj, Ciro Biancofiore, Michele Bonaldi +11
A minimal observable length is a common feature of theories that aim to merge quantum physics and gravity. Quantum mechanically, this concept is associated to a nonzero minimal unc…
Torsion pendulum revisited
Massimo Bassan, Fabrizio De Marchi, Lorenzo Marconi +3
We present an analysis of the motion of a simple torsion pendulum and we describe how, with straightforward extensions to the usual basic dynamical model, we succeed in explaining…
A quasi-complete mechanical model for a double torsion pendulum
Fabrizio De Marchi, Giuseppe Pucacco, Massimo Bassan +8
We present a dynamical model for the double torsion pendulum nicknamed PETER, where one torsion pendulum hangs in cascade, but off-axis, from the other. The dynamics of interest in…
The linear BESS model and the double Higgs-strahlung production
R. Casalbuoni, L. Marconi
In this paper we evaluate, in the context of the linear BESS model the cross-section for the double Higgs-strahlung process. We find that, within the bounds given by the actual exp…
