Staying Thermal with Hartree Ensemble Approximations
M. Salle, J. Smit, J. C. Vink
We study thermal behavior of a recently introduced Hartree ensemble approximation, which allows for non-perturbative inhomogeneous field configurations as well as for approximate t…
Thermalization in a Hartree Ensemble Approximation to Quantum Field dynamics
M. Salle, J. Smit, J. C. Vink
For homogeneous initial conditions, Hartree (gaussian) dynamical approximations are known to have problems with thermalization, because of insufficient scattering. We attempt to im…
Thermalisation of inhomogeneous quantum scalar fields in 1+1D
M. Salle, J. Smit, J. C. Vink
Using an improved version of the Hartree approximation, allowing for ensembles of inhomogeneous configurations, we show in a theory, that initially the system thermalises wi…
Finite Temperature Simulations from Quantum Field Dynamics?
M. Salle, J. Smit, J. C. Vink
We describe a Hartree ensemble method to approximately solve the Heisenberg equations for the ϕ^4 model in 1+1 dimensions. We compute the energies and number densities of the quant…
Damping and the Hartree Ensemble Approximation
M. Salle, J. Smit, J. C. Vink
We study a Hartree ensemble approximation for real-time dynamics in the toy model of 1+1 dimensional scalar field theory. Damping behavior seen in numerical simulations is compared…
Scalar Field Dynamics: Classical, Quantum and in Between
M. Salle, J. Smit, J. C. Vink
Using a Hartree ensemble approximation, we investigate the dynamics of the \f^4 model in 1+1 dimensions. We find that the fields initially thermalize with a Bose-Einstein distribut…
