Hello,
I was just wondering if there was a way to simulate the quantum annealing of a spin chain/lattice. Namely, adjust the parameters in a model file so that over the course of the quantum monte carlo simulation I could start with one hamiltonian (a simple heisenberg hamiltonian with nearest neighbour couplings and a transverse magnetic field) and finish with a different one (transverse field turned off).
Cheers, -Dan

Hi Dan,
What is the purpose of this? Do you want to use it to improve the simulation or to get some time-dependent measurements? The QMC codes only measure equilibrium properties at the given parameters and you can thus just do a series of simulations. Please remember that MC time and real time are not the same.
