An Efficient Geometric Integrator for Thermostatted Anti-/Ferromagnetic Models

Anti)-/ferromagnetic Heisenberg spin models arise from discretization of LandauLifshitz models in micromagnetic modelling. In many applications it is essential to study the behavior of the system at a fixed temperature. A formulation for thermostatted spin dynamics was given by Bulgac and Kusnetsov [5], which incorporates a complicated nonlinear dissipation/driving term while preserving spin le...

The Anti-ferromagnetic Vacuum

The ferromagnetic condensate is a well known device for mass generation in particle physics ever since the seminal work of Nambu and Jona-Lasinio. This condensate is a coherent state of particles with vanishing momentum. We suggest in this talk the use of another type of condensate in Quantum Field Theory which is a coherent state consisting of particles with non-zero momentum. The field operat...
