Description

  • Reorganized library code for big speedup of driver-code compile times.

  • Restored computation of quantum numbers of entanglement spectrum. It is now only done if requested by passing the (boolean) named arg "ComputeQNs".

  • Fixed bug where AutoMPO was not working for non-QN conserving operators (thanks Yifan Tian).

  • Fixed bug where Truncate=false was getting set back to true if other truncation args (Cutoff, Maxm) were set (thanks Bill Huggins).

  • Fixed autovector to allow types with non-constexpr default constructor.

  • Changed averageM(MPS) to return a Real instead of an int.

  • Broke up some big source files to aid compilation on Windows using cygwin.

  • Updates to tutorials for Sherbrooke summer school
