It is explained how field-theoretic methods and the dynamic renormalisation group (RG) can be applied to study the universal scaling properties of systems that either undergo a continuous phase transition or display generic ...

The contact process with diffusion (PCPD) defined by the binary reactions B+B→B+B+B, B+B→∅ and diffusive particle spreading exhibits an unusual active to absorbing phase transition whose universality class has long been ...

We numerically investigate the non-equilibrium critical dynamics in three-dimensional anisotropic antiferromagnets in the presence of an external magnetic field. The phase diagram of this system exhibits two critical lines ...

We construct a ‘mutant’ form of quantum mechanics on a vector space over the finite Galois field GF(q). We find that the correlations in our model do not violate the Clauser-Horne-Shimony-Holt (CHSH) version of Bell’s ...

Large, motile animals proliferated during the Cambrian explosion,540–515 million years ago,and this period has been associated with both rising and declining O2levels on Earth [1–3]. To explore this conundrum, we reconstructed ...

We present a model–independent analysis of the Zb¯b vertex, with the aim of constraining contributions of new physics to the left- and right–handed couplings of the b. We find that the left–handed coupling of the b is quite ...

A sterile neutrino is a lepton with no ordinary electroweak interaction except those induced by mixing... It is important to remember that sterile neutrino mixing in the disappearance channel can only be established by ...
