14. Time Measurement as Test of Quantum Mechanics

Mr Nicola Vona (LMU Munich)

21/06/2012, 09:30

Although time measurements are very often performed in experiments, their theoretical description is largely unclear. Several proposals have been put forward, two of which will be presented in this talk: the one resulting from the application of the orthodox quantum formalism, and that corresponding to the use of Bohmian Mechanics. A situation in which these two approaches lead to different...

15. Numerical Solutions of Quantum Problems via Bohmian Trajectories

Damiano Marian (GE)

The aim of the talk is to give an overview of the present status of numerical methods to solve quantum problems via Bohmian trajectories. Particularly I will focus on three relevant approaches for the numerical solution of the Time Dependent Schroedinger Equation (TDSE). The first, called Quantum Trajectory Methods (QTM), developed by Wyatt [1], provides a precise description of quantum...

16. Quantum-classical transition in optical twin beams and experimental applications to quantum metrology

Dr Ivano Ruo Berchera (INRIM)

The discrimination between quantum and classical states, besides its very important and deep conceptual relevance, has also recently received much attention due to the development of quantum technologies. On one side, it represents a fundamental point for the studies concerning the transition between quantum and classical world, one of the most intriguing research sectors in the foundations of...

17. The informational approach to quantum theory: probabilistic theories, quantum principles, and hidden variable models

Paolo Perinotti (PV)

21/06/2012, 11:30

We will briefly review the operational-probabilistic framework in which quantum theory can be formulated as a theory of information processing. The six principles constituting the axioms that lead to the Hilbert space formalism will be introduced. Relaxing any of these principles opens a wider and largely unexplored scenario, in which alternate theories are allowed. The possibility of...

18. Bohmian solution to the measurement of many-body systems: Sequential current in mesoscopic electron devices

Dr XAVIER ORIOLS (UNIVERSITAT AUTONOMA DE BARCELONA)

21/06/2012, 12:00

X.Oriols, F. L.Traversa, G. Albareda Departament d’ Enginyeria Electronica, Universitat Autonoma de Barcelona, 08193, Bellaterra, SPAIN Electronic industry is pushing devices into the few-nanometer (mesoscopic) limit, where mainly pure quantum e_ects determine the current owing through them. However, the accurate prediction of their multi-time current correlations is a very challenging...

19. Particle oscillations in collapse models

Sandro Donadi (TS)

21/06/2012, 12:30

Collapse models are phenomenological models developed to solve the measurement problem in Quantum Mechanics. In these models one assumes that the evolution of the wave function is driven by an equation obtained introducing new non-linear and stochastic terms in the Schr?dinger equation. Accordingly, collapse models make different predictions than Quantum Mechanics, so they can be tested. A...
