Installation & Uninstallation

Installation

Offline

1. Download the latest "TBMethod-<\*version #\*>.paclet" file to local machine;

2. Run PacletInstall["<*path-to-download*>/TBMethod-<*version #*>.paclet"].

Installation Test (1 → 3 or 2 → 3)

1. For single kernel, load the package by

Needs["TBMethod`"]

2. For parallel computation, load it by

Needs["TBMethod`"]
ParallelNeeds["TBMethod`"]

3. Check the installation by

Scan[Echo @* Information] @ {"TBMethod`MDConstruct`*", "TBMethod`EigenSpect`*", "TBMethod`LGFF`*", "TBMethod`DataVisualization`*"}

and four lists of functions should be indexed out.

Uninstallation

• Run PacletUninstall["TBMethod"]

Functionalities

• Highlights: fully employment of the NNS (nearest neighbor search) algorithm, so that the total computation complexity tends to be fine as:

  • Model construction linear in system's size $ \text{O}(n) $:

    • Generation of Hamiltonian matrices,
    • Adaptive partition of central scattering region

  • Calculation of transport related quantities:

    • 5-terminal Hall calculation in $ \text{O}(n^{1.7}) $
