Realization interface¶

The realization of your program is done here where you write up your implementation of your Hamiltonian or dissipator, and proceed for DMRG, tMPS, or TEBD.

MPS/MPS Core¶

Implementation of

MPS and MPO class
Time evolution scheme
- tMPS
- TEBD
DMRG scheme

gTensor dense tensor library¶

supports dense tensor operations

tensor arithmetic
contract
directSum
fusion
svdCompress
qrCompress
deparallise
permute

qTensor dense tensor library (with quantum numbers)¶

supports dense tensor operations with quantum numbers. The quantum numbers are used for symmetry matrix product state.

tensor arithmetic
contract
directSum
fusion
tieIndex
svdCompress
qrCompress
deparallise
permute
