Classical probabilistic realisation of quantum double-slit interference
Christof Wetterich
We demonstrate how the interference effects for a quantum particle in the double-slit experiment can be described by classical probabilities. We investigate a classical field theor…
Quantum observables for probabilistic classical particles
Christof Wetterich
The classical observables of position and momentum are not well adapted to particles in a microphysical situation where typical probability distributions are characterized by a sub…
Quantum evolution with classical fields
Christof Wetterich
Wave guides for classical electromagnetic fields can realize the discrete quantum evolution of the wave function for a system of qubits. Phase shifts, switches and beam splits allo…
Physical time for the beginning universe
Christof Wetterich
We propose that physical time is based on counting the oscillations of wave functions. The discrete counting of the ticks of these clocks does not depend on the metric frame. It re…
A Universe without expansion
C. Wetterich
We discuss a cosmological model where the universe shrinks rather than expands during the radiation and matter dominated periods. Instead, the Planck mass and all particle masses g…
Quantum fermions and quantum field theory from classical statistics
C. Wetterich
An Ising-type classical statistical ensemble can describe the quantum physics of fermions if one chooses a particular law for the time evolution of the probability distribution. It…
Lattice diffeomorphism invariance
C. Wetterich
We propose a lattice counterpart of diffeomorphism symmetry in the continuum. A functional integral for quantum gravity is regularized on a discrete set of space-time points, with…
Spinors in euclidean field theory, complex structures and discrete symmetries
C. Wetterich
We discuss fermions for arbitrary dimensions and signature of the metric, with special emphasis on euclidean space. Generalized Majorana spinors are defined for mod 8…
Probabilistic time
C. Wetterich
The concept of time emerges as an ordering structure in a classical statistical ensemble. Probability distributions at a given time obtain by integrating out the past…
Emergence of quantum mechanics from classical statistics
C. Wetterich
The conceptual setting of quantum mechanics is subject to an ongoing debate from its beginnings until now. The consequences of the apparent differences between quantum statistics a…
Invariants and nonlinear fields in Spinor Gravity
C. Wetterich
Spinor gravity is a functional integral formulation of gravity based only on fundamental spinor fields. The vielbein and metric arise as composite objects. Due to the lack of local…
Non-Equilibrium Time Evolution in Quantum Field Theory
C. Wetterich
The time development of equal-time correlation functions in quantum mechanics and quantum field theory is described by an exact evolution equation for generating functionals. This…
The cosmon model for an asymptotically vanishing time-dependent cosmological ``constant''
Christoph Wetterich
We investigate the coupled system of gravity and a scalar with exponential potential. The energy momentum tensor of the scalar field induces a time-dependent cosmological ``constan…
