A bstract We use the background field method to systematically derive CFT data for critical ϕ 6 vector model in three dimensions, and Gross-Neveu dimensions 2 ≤ d 4. Specifically, we calculate OPE coefficients anomalous of various operators, up next-to-leading order 1/ N expansion.

We introduce a numerical method and python package, chimes, that simulates quantum systems initially well approximated by mean field theory using second order extension of the classical approach. call this moment expansion method. In way, we can accurately approximate evolution first moments beyond where breaks down. This allows us to estimate break time approximation without any calculations e...

In the Nordic countries, a major part of built heritage is constructed wood and on churches it still common for roofing to consist shingles. 20th century, there was paradigm shift when authorities made new standards where, example, variety species used throughout history replaced by pine with sapwood. Today, evident that broken traditions have resulted in roofings shorter life spans (Göllas &am...
