Symmetry and Contextuality
Hartmann Römer
The general concept of symmetry is realized in manifold ways in different realms of reality, such as plants, animals, minerals, mathematical objects or human artefacts in literatur…
Generalized Quantum Theory: Overview and Latest Developments
Thomas Filk, Hartmann Römer
The main formal structures of Generalized Quantum Theory are summarized. Recent progress has sharpened some of the concepts, in particular the notion of an observable, the action o…
Order Effects in Sequential Measurements of Non-Commuting Psychological Observables
Harald Atmanspacher, Hartmann Roemer
Sequential measurements of non-commuting observables produce order effects that are well-known in quantum physics. But their conceptual basis, a significant measurement interaction…
Currents and the Energy-Momentum Tensor in Classical Field Theory: A fresh look at an Old Problem
Michael Forger, Hartmann Römer
We give a comprehensive review of various methods to define currents and the energy-momentum tensor in classical field theory, with emphasis on a geometric point of view. The neces…
A general construction of Poisson brackets on exact multisymplectic manifolds
Michael Forger, Cornelius Paufler, Hartmann Römer
In this note the long standing problem of the definition of a Poisson bracket in the framework of a multisymplectic formulation of classical field theory is solved. The new bracket…
The Poisson Bracket for Poisson Forms in Multisymplectic Field Theory
Michael Forger, Cornelius Paufler, Hartmann Roemer
We present a general definition of the Poisson bracket between differential forms on the extended multiphase space appearing in the geometric formulation of first order classical f…
