Prof. Detlef Duerr (Mathematisches Institut LMU)28/04/2014, 10:00Nature is not strange or mysterious or non understandable. Our modern theories are. Quantum Mechanics is often presented as such and that need not be. The talk addresses young researchers who have not been yet disillusioned that a reasonable physics description of nature is possible.Go to contribution page

Giacomo D'Ariano (PV)28/04/2014, 11:15ABSTRACT The Quantum Theory (QT) of abstract systems (qubits, fields, ?)has been recently derived from six axioms of pure information-theoretic nature. All these axioms have a strong epistemological connotation, and cannot be easily modified without reducing the practical experimental feasibility and epistemological power of the whole physics. On the other hand, as regards the ?Mechanics? of...Go to contribution page

Angelo Bassi (TS)28/04/2014, 12:00Abstract: We will introduce models of spontaneous wave function collapse (collapse models) as an alternative to standard quantum theory. The Schroedinger equation is modified by adding nonlinear and stochastic terms, which induce the collapse of the wave function. We will review the general properties of such models, in the light of the most recent results. We will present an overview of where...Go to contribution page

Dr Luca Ferialdi (LMU München)28/04/2014, 14:15Abstract: Open quantum systems are often described by a relevant system linearly coupled to an environment of independent harmonic oscillators. We show that, considering the collective motion of these oscillators, one can give an equivalent description where the environment is modeled by a chain of "collective modes" with first neighbors interaction. Such chain representation allows for a...Go to contribution page

Mr Dustin Lazarovici (Ludwig-Maximilians-University Munich)28/04/2014, 14:45Abstract Bell?s theorem manifests a tension between quantum non-locality and relativity by asserting that any realistic account of EPR-type correlations must admit non-local influences between distant events. We want to explore the possibility to mitigate this tension by admitting microscopic interactions that are both advanced and retarded, thus drawing exclusively on the resources of...Go to contribution page

Dr Mohammad Bahrami (research fellow)28/04/2014, 16:10Unification of gravity and quantum theory is still an unattained problem of modern physics. The traditional approach of quantizing the gravitational field has not yet provided us with a satisfying theory of quantum gravity. A different resolution is to modify quantum dynamics by adding nonlinear terms with gravitational origins. This line of research is highly motivated by semi-classical...Go to contribution page

Mr Kristian Piscicchia (LNF)28/04/2014, 16:40Our work is concerned with the investigation of the spontaneous emission, form orbital electrons and nuclear protons in Germanium atoms. The spontaneous emission of free electrons was first predicted and quantified by Q. Fu, as a consequence of electrons interaction with the stochastic field introduced in the non-relativistic Continuous Spontaneous Localization models. An innovative Bayesian...Go to contribution page

Dr Juan Leon (Instituto de Física Fundamental (CSIC))28/04/2014, 17:10LEON, Juan (Instituto de Fisica Fundamental (CSIC)) Creation and annihilation operators adding or subtracting well-defined amounts of energy and momentum to the field canonically describe particles, the elementary excitations of the fields, in QFT. These operators create quanta completely delocalized in space, at odds with the idea of particles as minute subdivisions of matter of finite...Go to contribution page

Dr Pierantonio Zanghi (Dipartimento di Fisica, Università di Genova INFN- Sezione di Genova)29/04/2014, 10:15The most puzzling issue in the foundations of quantum mechanics is perhaps that of the status of the wave function of a system in a quantum universe. Is the wave function objective or subjective? Does it represent the physical state of the system or merely our information about the system? And if the former, does it provide a complete description of the system or only a partial description? ...Go to contribution page

Dr marco gramegna (INRiM)29/04/2014, 11:30Time as an emergent property deriving from quantum correlations remains an open and controversial question among physicists. In fact, the ?problem of time? in essence stems from the fact that a canonical quantization of general relativity yields the Wheeler-DeWitt equation predicting a static state of the universe, contrary to obvious everyday evidence. Page and Wootters speculated that by...Go to contribution page

Prof. Lajos Diosi (Wigner Research Center for Physics)29/04/2014, 12:15Spontaneous collapses are thought to be masked by environmental decoherence. We refine this view and discuss the magnitude of spontaneous collapses under natural circumstances in elastic/hydrodynamic degrees of freedom of bulk matter.Go to contribution page

Dr Petros Wallden (Heriot-Watt University)29/04/2014, 15:00Abstract: Quantum theory allows sets of probabilities between spacelike separated parties that cannot be recovered from a local (realistic) theory as it is shown by violations of Bell's inequalities. The violation of Bell's inequalities is equivalent with proving that there does not exist a joint probability distribution for all the different (unrealised) alternatives. The non-existence...Go to contribution page

Tomer Barnea (Université de Genève)29/04/2014, 16:50The talk will explore the possibility to explain quantum correlations via (possibly) unknown causal influences propagating gradually and continuously at a finite speed v > c. This framework goes beyond quantum theory in the sense that it tries to provide an explanation for Bell inequality violating correlations that remains local and continuous in space and time. In previous work it could...Go to contribution page

Andre Grossardt (University of Trieste)30/04/2014, 11:30That gravity has to be quantised is usually considered an accepted truth among most physicists. However, there is virtually no conclusive evidence for this. The most obvious way to merge Quantum Mechanics with fundamentally classical gravity is provided by semi-classical gravity. For non-relativistic quantum systems this approach yields the Schr?dinger-Newton equation, a non-linear,...Go to contribution page

Mr Nathan Cooper (University of Southampton)30/04/2014, 12:00Abstract Matter-wave interferometry is well understood, and there have been several experimental demonstrations | even with particles as large and complex as molecules. While the centre of mass (COM) motion of such particles is controlled very precisely, internal spin properties can aect the motion if both degrees of freedom are coupled. This can be used in a twofold way: it can map the...Go to contribution page

Andrea Smirne (TS)30/04/2014, 12:30In this talk, I present a possible extension of the GRW collapse model [1,2], which avoids the infinite growth of the energy of the system. New jump operators are introduced, while the other defining features of the model are left unchanged. The jump operators correspond to the Fourier transform of the Lindblad operators of a model for collisional decoherence [3] and they depend on the...Go to contribution page
