Critical behaviour of driven bilayer systems: A field-theoretic renormalisation group study
We investigate the static and dynamic critical behaviour of a uniformly driven bilayer Ising lattice gas at half filling. Depending on the strength of the interlayer coupling J , phase separation occurs across or within the two layers. The former transitions are controlled by the universality class of model A (corresponding to an Ising model with Glauber dynamics), with upper critical dimension...
متن کاملStatic hole in a critical antiferromagnet: field-theoretic renormalization group
Subir Sachdev† Department of Physics, Yale University P.O. Box 208120, New Haven, CT 06520-8120, USA Abstract We consider the quantum field theory of a single, immobile, spin S hole coupled to a twodimensional antiferromagnet at a bulk quantum critical point between phases with and without magnetic long-range order. We present an alternative derivation of its two-loop beta function; the results...
متن کاملRenormalization Group Analysis of Driven Diffusive Systems
The critical properties of statistical systems in thermal equilibrium are well understood, thanks to renormalization group analysis. For systems driven into non-equilibrium steady states, many surprising new features appear. For example, when the Ising lattice gas is driven with biased diffusion or coupled to two thermal baths, long range correlations exist at all temperatures. The second order...
متن کاملField theoretic study of bilayer membrane fusion. I. Hemifusion mechanism.
Self-consistent field theory is used to determine structural and energetic properties of metastable intermediates and unstable transition states involved in the standard stalk mechanism of bilayer membrane fusion. A microscopic model of flexible amphiphilic chains dissolved in hydrophilic solvent is employed to describe these self-assembled structures. We find that the barrier to formation of t...
متن کاملDynamically Driven Renormalization Group
We present a detailed discussion of a novel dynamical renormalization group scheme: the Dynamically Driven Renormalization Group (DDRG). This is a general renormalization method developed for dynamical systems with non-equilibrium critical steady-state. The method is based on a real space renormalization scheme driven by a dynamical steady-state condition which acts as a feedback on the transfo...
