Finite temperature calculation using MPS
Dear ALPS users, I wish to do finite temperature calculations for the Bose-Hubbard model. Is it possible to do so using the ALPS MPS application? Any help will be appreciated. Regards- Manpreet
Dear Manpreet, Sorry for the last reply. Under my knowledge of ALPS MPS project, the main applications in the toolbox are: 1. ”mps_optim” Target ground state and several low energy excited states. 2. ”mps_evolve” Evolve an initial MPS under the real-time using a given Hamilton. 3. ”mps_meas” Measure observables which are not measured at the runtime when you run the above two applications. 4. ”mps_overlap” lite command line application to calculate the overlap of two MPSs which is easy to integrate into other scripts.

Finite temperature calculations for that model are best done by QMC

Dear Prof. Matthias and Rongyang, Thank you for the response. Apart from the Bose Hubbard model I wish to do finite temperature calculations for Bose-Fermi mixtures as well. Is there a way to implement it using the existing ALPS MPS application? Regards- Manpreet On Wed, Mar 13, 2019 at 8:38 PM Matthias Troyer <troyer@phys.ethz.ch> wrote:

The ALPS MPS application is only for ground states and low lying excited states
