Synchronization of thermal Clocks and entropic Corrections of Gravity

Andreas Schlatter There are so called MOND corrections to the general relativistic laws of gravity, able to explain phenomena like the rotation of large spiral galaxies or gravitational lensing by certain galaxy clusters. We show that these corrections can be derived in the framework of synchronizing thermal clocks. We develop a general formula, which reproduces the deep MOND correction at large scales and...

On the Status of the Measurement Problem: Recalling the Relativistic Transactional Interpretation

ABSTRACT. In view of a resurgence of concern about the measurement problem, it is pointed out that the Relativistic Transactional Interpretation (RTI) remedies issues previously considered as drawbacks or refutations of the original TI. Specifically, once one takes into account relativistic processes that are not representable at the non-relativistic level (such as particle creation and annihilation, and virtual propagation), absorption...

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...

Quantum mechanics from an epistemic state space

Per Östborn (Lund University, Sweden) We derive the Hilbert space formalism of quantum mechanics from epistemic principles. A key assumption is that a physical theory that relies on entities or distinctions that are unknowable in principle gives rise to wrong predictions. An epistemic formalism is developed, where concepts like individual and collective knowledge are used, and knowledge may be actual... Read more →

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 →
