The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; .

The threshold for creep in the Bean critical state is investigated. We perturb the Bean state by an energy $\Delta\epsilon$. We find that no matter how small $\Delta\epsilon$ is it will always be able to induce creep somewhere on the Bean profile. This finding has important consequences for the interpretation of low temperature creep phenomena in terms of quantum creep.

The paper
Original abstract

The threshold for creep in the Bean critical state is investigated. We perturb the Bean state by an energy $\Delta\epsilon$. We find that no matter how small $\Delta\epsilon$ is it will always be able to induce creep somewhere on the Bean profile. This finding has important consequences for the interpretation of low temperature creep phenomena in terms of quantum creep.
