Midas 2025.07.0

This is a special out-of-cycle feature release of MidasCpp.

New Features

• A quantum phase estimation module with low-rank factorization of the Hamiltonian.
• Output of two-mode densities have been implemented for the MCTDH and TD(M)VCC methods
• The two-mode density for all WFs can be outputted in either TOML format or as a simple .dat file.
  
  

Source code changes

• The "elementary operator" OpDef has been generalized to the n-mode case such that it can be used to calculate n-mode density tensors.
• MIDASERROR will now end with a call to util::Unreachable(). Error number mode of MIDASERROR has been removed, so MIDASERROR will now either exit the program or throw an exception, which means that whatever comes after a MIDASERROR will never ever be called. Calling util::Unreachable has the effect of not needing to return dummy arguments from functions after a MIDASERROR is thrown.
• MidasAssert renamed to MIDASASSERT.
