Path integral spin dynamics with exchange and external field
Thomas Nussle, Stam Nicolis, Iason Sofos +1
In this work, we propose a path integral-inspired formalism for computing the quantum thermal expectation values of spin systems, when subject to magnetic fields that can be time-d…
Path integral spin dynamics for quantum paramagnets
Thomas Nussle, Pascal Thibaudeau, Stam Nicolis
A path integral method, combined with atomistic spin dynamics simulations, has been developed to calculate thermal quantum expectation values using a classical approach. In this st…
Numerical Simulations of a Spin Dynamics Model Based on a Path Integral Approach
Thomas Nussle, Stam Nicolis, Joseph Barker
Inspired by path integral molecular dynamics, we build a spin model, in terms of spin coherent states, from which we can compute the quantum expectation values of a spin in a const…
Dynamic magnetostriction for antiferromagnets
Thomas Nussle, Pascal Thibaudeau, Stam Nicolis
In this paper we study the switching properties of the dynamics of magnetic moments, that interact with an elastic medium. To do so we construct a Hamiltonian framework, that can t…
Probing magneto-elastic phenomena through an effective spin-bath coupling model
Thomas Nussle, Pascal Thibaudeau, Stam Nicolis
A phenomenological model is constructed, that captures the effects of coupling magnetic and elastic degrees of freedom, in the presence of external, stochastic perturbations, in te…
A group action principle for Nambu dynamics of spin degrees of freedom
Stam Nicolis, Pascal Thibaudeau, Thomas Nussle
We describe a formulation of the group action principle, for linear Nambu flows, that explicitly takes into account all the defining properties of Nambu mechanics and illustrate it…
Coupling magneto-elastic Lagrangians to spin transfer torque sources
Thomas Nussle, Pascal Thibaudeau, Stam Nicolis
The consequences of coupling magnetic and elastic degrees of freedom, where spins and deformations are carried by point-like objects subject to local interactions, are studied, the…
Nambu mechanics for stochastic magnetization dynamics
Pascal Thibaudeau, Thomas Nussle, Stam Nicolis
The Landau-Lifshitz-Gilbert (LLG) equation describes the dynamics of a damped magnetization vector that can be understood as a generalization of Larmor spin precession. The LLG equ…
