About Beatrix Hiesmayr Beatrix Hiesmayr received her PhD from the University of Vienna in 2002. At even higher energies nonlinear phenomena take place which lead to the unitarization of the cross section and the saturation of the hadronic wavefunction. . We show that quantum information in a re. Future experiments, based on interferomet. Abstract: Unitary transformations and density matrices are central objects in quantum physics and various tasks require to introduce them in a parameterized form. Bell inequalities or decoherence models for systems in high energy physics.

Next. We analize the non-cyclic geometric phase for neutrinos propagating in the matter and through a magnetic field. We find that the geometric phase and the total phase associated to the mixing phenomenon provide a theoretical tool to distinguish between Dirac and Majorana neutrinos.

NextWe analyze the non-cyclic geometric phase for neutrinos. Discrete symmetries such as parity P , charge-conjugation C and time reversal T are of fundamental importance in physics and cosmology. The history of Bertlmann's socks 00:00:21 3. . . .

NextTesting quantum foundations for systems in high energy physics gets currently more and more attention e. Therefore, using Hamiltonians for entanglement detection is in principle a very promising approach, as used in the concept of the entanglement gap as defined in Ref. The conventional approach to test collapse models is to create spatial supe. Jänner 2009 Uni Wien F-theory: Introduction and recent developments Fourteen years ago, string theory underwent a major paradigm shift when techniques were developed to study the theory non- perturbatively, i. Last but not least it is demonstrated how the maximally possible degree of violation of a Bell inequality, using the Pauli-Lubanski spin observable, can be recovered by any inertial observer. However, as this criterion only works for thermal states and requires optimisation over all mixed separable or k-separable states as the optimised function is not linear , it is much less useful for practical and computational reasons than the concept of the entanglement gap or the k-entanglement-gap, respectively. Our results hold for neutrinos propagating in vacuum and through the matter.

NextWe find that the geometric phase and the total phase associated to the mixing phenomenon and to the neutrino spin rotation can represent a tool to distinguish between Dirac and Majorana neutrinos. Useful tools for this purpose are entanglement witnesses; they provide a geometrically intuitive method to detect entanglement. Hiesmayr was formed in 2008 at the University of Vienna. Considering the change of purity and entanglement in time we find that, despite the fact that only two degrees of freedom at a certain time can be measured, the neutral kaon system does not behave like a bipartite qubit system. . Abstract: We show that the relation between nonlocality and entanglement is subtler than one naively expects.

NextEven in environments which would strongly suggest the dominance of decohering effects hot surfaces, phonon vibrations quantum coherent scattering patterns remain visible. Dezember 2008 Uni Wien Physics analysis at Belle The aim of physics analysis is to match the predictions of theory with experimental results. . . It may exhibit black hole solutions, graviton modes and asymptotically Anti-deSitter solutions. We utilize a model denoted the Temporal Wave Function T. While the actual role of entanglement in nature is still widely unclear and attracts much attention and speculation entanglement might e.
