Hi all,
Sorry for the radio silence, but I've been travelling. As Matthais said, it would be useful if you could send us some numbers, for different sizes, and number of DMRG states.
Saludos, <ADRIAN>

How many states do you keep?

Hi Dear Thanks for your consideration.I run the program for different sizes and have increased it to 500 sites.For up to 100 site the result converges but it is not the result that should it be (*0.443147*),the result that have achieved earlier from Bethe method and in the work of Mr.white that tests the DMRG for showing the powerful of this code. Thanks zhian

I have changed m&sweep& number of sites(to 1000 site) but my result just 2 digit concur with 0.443147. I don't know what must i do. I will be very appreciate if you can guide me. Thanks zhian
