WannierTools V2.7.1

1. Added a functional to study topological superconductor
2. Reduce the difficulty to compile. You can compile WannierTools without ARPACK if you don't want to study large-scale systems.

WannierTools v2.7.0

New functionalities includes:

1. Anomalous Nernst Effect (ANE_calc), developed by Hanqi Pi (hqpi@iphy.ac.cn).
2. Spin Hall Conductivity calculation (SHC_calc) by QSWu (quansheng.wu@iphy.ac.cn).
3. A new functionality for calculating valley-resolved energy bands in twisted systems, upon creation of the valley operator. This feature, still in development, was written by QSWu and Ziyue Qi.
4. Fixed several bugs about the unit conversion between Angstrom and Bohr.

WannierTools V2.6.2

A version for Wannier 2022 Summer School Trieste

WannierTools V2.6.1

1. Fixed Several bugs in Sigma_OHE.f90 in V2.6.0.
2. Added one example "examples/electron-hole-compensated" to study the magnetoresistance of an electron-hole compensated model.
3. In this version, ARPACK and Intel MKL are required.

WannierTools V2.6.0

1. Now we use the atomic unit during the calculation, but use the conventional unit in the input file and output file. If not specified in the wt.in or WT.out, the unit of energy is eV, the length unit is Angstrom.
2. We create a new format to store the tight-binding model when the unit cell is huge. Such format is called the sparse hr format, it only stores the non-zero Hmn(R) entries instead of storing every unit as it's defined in Wannier90. One example is shown in ../examples/TDBG_1.89degree/TDBG_m17_hr.dat.tar.gz
3. We support the band structure, edge states, Wilson loop, Landau level calculations for twisted graphene systems.
4. Landau level calculations are supported.
5. For the band unfolding, we support BulkBand_unfold_line_calc, BulkBand_unfold_plane_calc, QPI_unfold_plane_calc modes.
6. For the Berry curvature, we support Berrycurvature_kpath_EF_calc, BerryCurvature_kpath_Occupied_calc, BerryCurvature_slab_calc, Berrycurvature_EF_calc, BerryCurvature_Cube_calc.

WannierTools V2.5.1

We release one version for the Wannier90 tutorial 2020.

WannierTools V2.5.0

In this version, we release two important functionalities.

1. Ordinary magnetoresistance calculation for non-magnetic metals and semimetals.
2. Energy band unfolding of supercell calculation.

WannierTools V2.4.1

1. Fixed several bugs about memory leaking.
2. Merge fermiarc, spintexture into one file, so that there is no spintexture.f90 any more.
3. Added an INSTALL file for the illustration of installation.

WannierTools V2.4.0

Sep 1 2018

1. We have a big update in this version since Changming Yue put his symmetrization code into WannierTools.
   So now we can symmetrize the Wannier functions based tight binding model. This funcionality is included
   in the wannhr_symm/ folder.

2. Fixed a bug about reading Rcut.

3. Distinguish two dual surface in the slab band calculation.

4. Update an example about calculating the mirror Chern number of ZrTe.

WannierTools V2.3.1

Update:

1. Support the Phonon system. Including generating tight-binding Hamiltonian with phonon_hr.py. Please set Particle='phonon' in the TB_FILE namelist when running wt.x.
2. fixed some bugs in finding nodes in the phonon system.
