Duration and its relation to the structure of space-time II

Andreas Schlatter We assign to the radiation vacuum the role of a universal observer with a corresponding universal clock. By demanding that the thermal clock of a gravitationally accelerated observer in its local rest frame marches in step with the universal one, we derive relations between energy content and geometry of space-time.

Quantum jumps and electrodynamical description

Leonardo Chiatti (ASL VT Medical Physics Laboratory) The customary description of radiation processes provided by Quantum Electrodynamics (QED) allows the quantitative derivation of many physical observables, in line with experiments. This extraordinary empirical success, however, leaves open the problem of the ontology of these processes. We identify these with the discontinuities of the evolution of the quantum state of the...

On testing the simulation hypothesis

Tom Campbell, Houman Owhadiy, Joe Sauvageauz, David Watkinson Can the hypothesis that reality is a simulation be tested? We investigate this question based on the assumption that if the system performing the simulation is fi nite (i.e. has limited resources), then to achieve low computational complexity, such a system would, as in a video game, render content (reality) only at the moment that information...

Electron-photon interaction and thermal disequilibrium irreversibility

Umberto Lucia (Politecnico di Torino) Atoms continuously interact with the photons of the electromagnetic fields in their environment. This electromagnetic interaction is the consequence of the thermal non-equilibrium. It introduces an element of randomness to atomic and molecular motion, which brings to the decreasing of path information required for microscopic reversibility of evolution. In any atomic electron-photon interaction an energy... Read more →

Duration and its Relationship to the Structure of Space-Time

Andreas Schlatter The notion of duration is a fundamental feature of intuitive time. Under the assumption that the duration of a measurement is defined to produce a result with certainty, we define a universal observer who observes the position of a physical system. We investigate what conclusions for the structure of space-time the universal observer can draw. It turns out that the perspective... Read more →

Can the Many-Worlds Interpretation be probed in Psychology?

Heinrich Päs (Technische Universität Dortmund) A minimal approach to the measurement problem and the quantum-to-classical transition assumes a universally valid quantum formalism, i.e. unitary time evolution governed by a Schrödinger-type equation. As had been pointed out long ago, in this view the measurement process can be described by decoherence which results in a "Many-Worlds" or "Many-Minds" scenario according to Everett and Zeh. A silent... Read more →

Quantum measurements as weighted symmetry breaking processes: the hidden measurement perspective

The purpose of the present note is twofold. Firstly, we highlight the similarities between the ontologies of Kastner's possibilist transactional interpretation (PTI) of quantum mechanics - an extension of Cramer's transactional interpretation - and the authors' hidden-measurement interpretation (HMI). Secondly, we observe that although a weighted symmetry breaking (WSB) process was proposed in the PTI, to explain the actualization of incipient transactions,... Read more →

Violation of the Born Rule: Implications for Macroscopic Fields.

ABSTRACT. It is shown that violation of the Born Rule leads to a breakdown of the correspondence between the quantum electromagnetic field and its classical counterpart. Specifically, the relationship of the quantum coherent state to the  classical electromagnetic field turns out to imply that if the Born Rule were violated, this could result in apparent deviations from the energy conservation...

Non-Relativistic Limit of the Dirac Equation

Muhammad Adeel Ajaib (California Polytechnic State University) We show that the first order form of the Schrodinger equation proposed in [1] can be obtained from the Dirac equation in the non-relativistic limit. We also show that the Pauli Hamiltonian is obtained from this equation by requiring local gauge invariance. In addition, we study the problem of a spin up particle... Read more →

Event ontology in quantum mechanics and downward causation

Rodolfo Gambini (Instituto de Fsica, Facultad de Ciencias) and Jorge Pullin (Louisiana State University) We show that several interpretations of quantum mechanics admit an ontology of objects and events. This ontology reduces the breach between mind and matter. When humans act, their actions do not appear explainable in mechanical terms but through mental activity: motives, desires or needs that propel them to action. These... Read more →

Thought experiment of the reality of matter wave

Takeshi Yamaguchi (Tokyo Institute of Technology) A thought experiment regarding the light-wave diffraction by a matter-wave lattice is proposed. Matter-wave diffraction by an optical-lattice is already a well-established experimental technology, therefore, its symmetrical phenomenon, i.e., light-wave diffraction by a matter-wave lattice, does not seem to be unlikely. If the diffracted light could be observed, it would suggest the presence of... Read more →
