Re: Error with resuming dmrg calculation

My dirty workaround solution would be to add a line between 544 and 545 in simulation.py as follows: params = self.options.subconfig('algorithm_params') #line 544 if 'min_sweeps' in params: params['min_sweeps']=kwargs['resume_data']['sweeps'] #line that updates the min_sweep condition according to p...

Re: Error with resuming dmrg calculation

Previously, I had this message as a post-script, but I have decided to submit it as a separate message: I think I should also provide my attempt at debugging. Feel free to ignore my attempt. Short explanation: In the method tenpy.simulations.ground_state_search.GroundStateSearch.init_algorithm , ' r...

Error with resuming dmrg calculation

Hello! I have been using TeNPy for investigating a custom model on a cluster provided by my university. For this reason, I have been using the ‘simulation’ interface of TeNPy. However, I have been having trouble continuing calculations that are interrupted before converging due to the time limits on...

Re: Issue with Missing Subscripts on Fermionic Operators in all_coupling_terms().to_TermList() Output

Hi again, I wanted to provide additional information. I have encountered a similar problem when using the add_multi_coupling function for defining four-point interactions. More relevant to my project I am trying to implement intearctions of the form: f^\dagger_{i\downarrow}f_{i\uparrow}f^\dagger_{i+...

Issue with Missing Subscripts on Fermionic Operators in all_coupling_terms().to_TermList() Output

Hi everyone. I am new to TeNPy and currently working on a project involving spin-half fermions. I’ve come across an issue with the output format from the all_coupling_terms().to_TermList() when using the add_coupling function for defining hopping terms. Description of the Issue: The output seems to ...
