Open Source Software of the Carr Theoretical Physics Research Group

Open Source MPS Released

We released on SourceForge open source code in 2014 during the APS March Meeting which supersedes Open Source TEBD. This code includes variational ground state search rather than imaginary time propagation, variational search for excited states (eMPS), TEBD-style time evolution for nearest-neighbor Hamiltonians, Krylov-based time evolution for long-range Hamiltonians, and algorithms for infinite lattices. The code will also support conservation of an arbitrary number of Abelian symmetries, easy parallelization over inputs, and a powerful python front end for designing, dispatching, and post-processing simulations.

Matrix Product State (MPS) Simulations

Numerical routines for variational matrix product state simulations.

Time-Evolving Block Decimation (TEBD) Simulations (Deprecated)

TEBD simulates the dynamics of entangled quantum many-body systems.

The above image displays the emergent saturation of spatial entanglement in the Molecular Hubbard Hamiltonian. The data was generated using the Open Source TEBD code.
