Field-theory approaches to nonequilibrium dynamics
(Springer-Verlag Berlin, 2007-01-01)
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 ...
Coupled two-species model for the pair contact process with diffusion
(American Physical Society (APS), 2020-10-22)
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 ...
Critical dynamics of anisotropic antiferromagnets in an external field
(American Physical Society (APS), 2020-03-03)
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 ...
Some Mutant Forms of Quantum Mechanics
(Amer Inst Physics, 2012-01-01)
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 ...
Atmosphere-ocean oxygen and productivity dynamics during the Cambrian explosion
(2019-08-21)
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 ...
An analysis of nonoblique corrections to the Zb¯b vertex
(1994)
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 ...
The K2K SciBar detector
(Elsevier Science Bv, 2004-12-11)
Sterile Neutrino Searches with Sources and Reactors
(2016-05-31)
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 ...
