Probabilistic cellular automaton for quantum particle in a potential
C. Wetterich
We propose that a quantum particle in a potential in one space dimension can be described by a probabilistic cellular automaton. While the simple updating rule of the automaton is…
Cellular automaton for spinor gravity in four dimensions
C. Wetterich
Certain fermionic quantum field theories are equivalent to probabilistic cellular automata, with fermionic occupation numbers associated to bits. We construct an automaton that rep…
Quantum gravity and scale symmetry in cosmology
C. Wetterich
We discuss predictions for cosmology which result from the scaling solution of functional flow equations for a quantum field theory of gravity. A scaling solution is necessary to r…
Scaling solution for field-dependent gauge couplings in quantum gravity
C. Wetterich
Quantum gravity can determine the dependence of gauge couplings in a scalar field, which is related to possible fifth forces and time varying fundamental "constants". This predicti…
Fermion picture for cellular automata
C. Wetterich
How do cellular automata behave in the limit of a very large number of cells? Is there a continuum limit with simple properties? We attack this problem by mapping certain classes o…
The quantum gravity connection between inflation and quintessence
C. Wetterich
Inflation and quintessence can both be described by a single scalar field. The cosmic time evolution of this cosmon field realizes a crossover from the region of an ultraviolet fix…
