DESCRIPTION:by Prof. Angelo Bassi\nUniversità degli Studi di Trieste\n\n
Abstract:\n\nTo make quantum theory consistent\, models of spontaneous wav
e function collapse (collapse models) propose to modify the Schrödinger e
quation by including nonlinear and stochastic terms\, which describe the c
ollapse of the wave function in space. These spontaneous collapses are “
rare” for microscopic systems\, hence their quantum properties are left
almost unaltered. At the same time\, since the collapses add coherently in
composite systems\, macroscopic spatial superpositions of macro-objects a
re rapidly suppressed. I will review the main features of collapse models\
, and will present an update of the most promising ways of testing them in
interferometric and non-interferometric experiments\, showing the current
lower and upper bounds on their parameters. Next\, I will discuss ideas t
o connect the collapse of the wave function to gravity: The Diosi-Penrose
model\, Adler’s model and the Schroedinger-Newton equation. I will also
show how collapse models can possibly shed a light on some cosmological pr
oblems. \n\nhttp://indico.smi.oeaw.ac.at/event/302/
