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…
Quantum Magnets and Matrix Lorenz Systems
Julien Tranchida, Pascal Thibaudeau, Stam Nicolis
The Landau--Lifshitz--Gilbert equations for the evolution of the magnetization, in presence of an external torque, can be cast in the form of the Lorenz equations and, thus, can de…
Information processing with Page-Wootters states
S. Nicolis
In order to perceive that a physical system evolves in time, two requirements must be met: (a) it must be possible to define a "clock" and (b) it must be possible to make a copy of…
