| Feb 10, 2019 at 15:57 | comment | added | Fracton | I really want to understand what is the advantage of talking about t-DMRG in terms of MPS ansatz rather than traditional terms in which it was first formulated. | |
| Feb 10, 2019 at 15:52 | comment | added | Fracton | I don't get it, I find that MPS is a way to reorganize and rewrite the coefficients. Please correct me if I am wrong about this. | |
| Feb 1, 2019 at 15:09 | comment | added | Sunyam | Using singular value decomposition on wave function expansion coefficients, you can proove MPS representation for arbitrary many body wave function. In this step, if I am correct you dont reduce any complexity. I think you further need to assume/approximate some value bond dimensions. If you impose bond dimensions to be unity i. e., matrices of MPS are scalars, then you will have simple standard mean field ansatz. | |
| Feb 1, 2019 at 13:12 | comment | added | Fracton | I want to understand the of how the complexity for $ C^i's $ scales down and what really is the basis for MPS and how does link up to mean field theory. | |
