Dear alps team,
I asked for the basis staties and hamiltonian matrix for the system described by parameters in case of exact diagonalization. Dr Matthias Troyer told me of a program in alps/model directory. This program is print_numeric and it displays the basis states and hamiltonian matrix.
Now I am interested with the basis states of lowest energy, as in case case of sparsediag which only has lowest energy states or fulldiag with firse states. I want that as sparse diag or full diag give the output energies it also gives the corresponding states along with those energies. this is what I want, then I can use the lowest energy basis states for my research as the professor will told me.
I have look in the alps code it hard for me as i dont know c++ of the level it needs and learning c++ is taking much of the time.
If the author of the program write a small routine just as print_numeric, it will serve my purpose, it will be great help of me.
Otherwise please tell me to look in what files or modify what programs that i get the basis state of the model corresponding to its energy.
Best Regards Khalid Loane
