Nature 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.

Abstract: 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...

Abstract
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...

Unification 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...

Our 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...

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...

The 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? ...

Time 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...

Spontaneous 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.

Abstract: 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...

The 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...

MAQRO is a proposed fundamental science mission to test the foundations of quantum physics. Over the last decades, the technology available in space has reached a level that will soon allow performing quantum experiments in space. Although, space experiments are an expensive and time-consuming business, the technological developnent may soon render space interesting as an environment for...

That 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,...

Abstract
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...
