0. New experimental limit on the Pauli Exclusion Principle violation by electrons - the VIP experiment

Entanglement, Symmetrisation Principle

The Pauli Exclusion Principle (PEP), reflecting the spin-statistics connection, represents a fundamental principle of the modern physics. Even if today there are no compelling reasons to doubt its validity, it still spurs a lively debate on its possible limits, as testified by the abundant contributions found in the literature and in topical conferences. We present a method of searching for...

Entanglement, Symmetrisation Principle

The characterization of entanglement is a fundamental issue for Quantum Information Theory. But the definition of entanglement depends on the notion of locality, and thus on the tensor product structure of the state space of the composite system. This notion is affected by the presence of superselection rules that restrict the accessible Hilbert space to a direct sum of subspaces. ...

39. What has CP violation to do with nonlocality?

Entanglement, Symmetrisation Principle

I show how basic questions of quantum mechanics can be investigated for systems in high energy physics. In particular the massive kaon-antikaon system is specially suitable as it offers a unique laboratory to tests various aspects of particle physics as well to test the foundations of quantum mechanics (e.g tests of Bell inequalities, local realistic theories, quantum marking and erasure...

38. Symmetry aspects in emergent quantum mechanics

Entanglement, Symmetrisation Principle

There is an energy-parity symmetry hidden in the Liouville equation, which resembles the one proposed recently by Randall and Sundrum as protective symmetry for the cosmological constant. We argue heuristically that this symmetry should be broken due to the coarse-graining which is inherent in physics, say, of the Standard Model, when the fundamental scale related to spacetime is the Planck...

55. Exotic statistics in string cosmology

Entanglement, Symmetrisation Principle

We discuss the origin of exotic statistics, in the sense of Tsallis, in the context of certain models of string cosmology, in which the dilaton expectation value, and hence the string coupling, are "fuzzy".Situations like this can characterize some versions of string spacetime foam. The effect of such stochastically fluctuating spacetimes on particle statistics is examined, determining the...

116. Canonical Commutation Relations and Adiabatic Parasites

Prof. Chryssomalis Chryssomalakos (Universidad Nacional Autonoma de Mexico)

12/12/2008, 19:35

The central theme of the talk is the study of a quantum particle, constrained to move in the neighborhood of a space curve, and its backreaction on the curve, viewed, in its turn, as a quantum system. In particular, the effect of this symbiosis on the canonical commutation relations of the 1+1 effective quantum field theory of the curve is studied, and potential implications are outlined.
