Big Toy Models: Representing Physical Systems As Chu Spaces
We pursue a model-oriented rather than axiomatic approach to the foundations of Quantum Mechanics, with the idea that new models can often suggest new axioms. This approach has often been fruitful in Logic and Theoretical Computer Science. Rather than seeking to construct a simplified toy model, we aim for a ‘big toy model’, in which both quantum and classical systems can be faithfully represen...
متن کاملToy Models for Retrocausality
A number of writers have been attracted to the idea that some of the peculiarities ofquantum theory might be manifestations of ‘backward’ or ‘retro’ causality, underlying thequantum description. This idea has been explored in the literature in two main ways:firstly in a variety of explicit models of quantum systems, and secondly at a concep-tual level. This note introduces a...
متن کاملLecture 2 ENSO toy models
Let us consider first a heuristic derivation of an equation for the sea surface temperature in the East Pacific, which will be followed by a more rigorous derivation in the following sections. Assume that the East Pacific SST affects the atmospheric heating and thus the central Pacific wind speed. The resulting wind stress, in turn, excites equatorial Kelvin and Rossby ocean waves. These waves ...
متن کاملToy models for wrapping effects
The anomalous dimensions of local single trace gauge invariant operators in N = 4 supersymmetric Yang-Mills theory can be computed by diagonalizing a long range integrable Hamiltonian by means of a perturbative asymptotic Bethe ansatz. This formalism breaks down when the number of fields of the composite operator is smaller than the range of the Hamiltonian which coincides with the order in per...
متن کاملStructural Susceptibilities in Toy Models of Proteins
New definitions of the structural susceptibilities based on the fluctuations of distances to the native state of toy protein models are proposed. The calculation of such susceptibilities does not require the basin of native state and the folding temperature can be defined from their peak if the native conformation is compact. The number of peaks in the derivatives of distances to the native sta...
