Physical Review E 2020年 第6期102卷 062141-062141页
作者: Hendrik Schawe Alexander K. Hartmann Laboratoire de Physique Théorique et Modélisation UMR-8089 CNRS CY Cergy Paris Université 95000 Cergy France Institut für Physik Universität Oldenburg 26111 Oldenburg Germany
We study an agent-based model of animals marking their territory and evading adversarial territory in one dimension with respect to the distribution of the size of the resulting territories. In particular, we use soph... 详细信息

Percolation of Fortuin-Kasteleyn clusters for the random-bond Ising model
收藏 引用
Physical Review E 2020年 第1期102卷 012131-012131页
作者: Hauke Fajen Alexander K. Hartmann A. P. Young Institut für Physik Universität Oldenburg 26111 Oldenburg Germany Physics Department University of California Santa Cruz Santa Cruz California 95064 USA
We apply generalizations of the Swendson-Wang and Wolff cluster algorithms, which are based on the construction of Fortuin-Kasteleyn clusters, to the three-dimensional ±1 random-bond Ising model. The behavior of ... 详细信息

Microscopic magnetic Hamiltonian for exotic spin textures in metals
收藏 引用
Physical Review B 2020年 第7期102卷 075106-075106页
作者: Deepak S. Kathyat Arnob Mukherjee Sanjeev Kumar Department of Physical Sciences Indian Institute of Science Education and Research (IISER) Mohali Sector 81 S.A.S. Nagar Manauli PO 140306 India
We derive and study a microscopic spin Hamiltonian on a lattice for Rashba-coupled double exchange metals. The Hamiltonian consists of anisotropic interactions of the Dzyaloshinskii-Moriya and pseudodipolar form, in a... 详细信息

Nonlocal stochastic-partial-differential-equation limits of spatially correlated noise-driven spin systems derived to sample a canonical distribution
收藏 引用
Physical Review E 2020年 第5期102卷 052112-052112页
作者: Yuan Gao Jeremy L. Marzuola Jonathan C. Mattingly Katherine A. Newhall Department of Mathematics University of North Carolina at Chapel Hill CB 3250 Chapel Hill North Carolina 27599-3250 USA Department of Mathematics and Department of Statistical Sciences Duke University Box 90320 Durham North Carolina 27708-0320 USA
For a noisy spin system, we derive a nonlocal stochastic version of the overdamped Landau-Lipshitz equation designed to respect the underlying Hamiltonian structure and sample the canonical or Gibbs distribution while... 详细信息

One-dimensional model for chemotaxis with hard-core interactions
收藏 引用
Physical Review E 2020年 第2期101卷 022419-022419页
作者: Tertius Ralph Stephen W. Taylor Maria Bruna Department of Mathematics University of Auckland Private Bag 92019 Auckland 1142 New Zealand Department of Applied Mathematics and Theoretical Physics Centre for Mathematical Sciences Wilberforce Road University of Cambridge Cambridge CB3 0WA United Kingdom
In this paper we consider a biased velocity jump process with excluded-volume interactions for chemotaxis, where we account for the size of each particle. Starting with a system of N individual hard rod particles in o... 详细信息
