How is it going with the entropy calculation? One thing you can do to make that easier is to let the bandwidth go to zero. Then I think it becomes simply a counting problem. e.g., there is only one way to have all spins up, while there are many ways to have some spins up and some down. How many are there actually? Anybody?
