"Testing the limits of quantum mechanics using micro-magnetomechanical 
systems"

Friday April 10 2015 - 2:30 pm
Lecture room 204, 2nd floor, Leonardo Building

ABSTRACT
I propose to experimentally investigate micro-magnetomechanical systems 
made of superconducting particles with size in the micron range, 
levitated in a magnetic trap. These systems have been recently suggested 
as a possible platform for the exploration of the macroscopic limits of 
quantum mechanics. I will illustrate the advantages of this approach, 
compared to other techniques like matter-wave interferometry or 
optically levitated nanoparticles. In particular, it is argued that 
conventional decoherence can be radically suppressed by operation at 
subkelvin temperature, enabling to achieve a regime where spontaneous 
wavefunction collapse models may become testable in a relevant range of 
parameters. I will introduce some specific levitation schemes and 
discuss experimental prospects and potential issues.


Everyone interested in the topic is welcome
