Detailed Description

field strength construction.

This class constructs a field strength, Fmunu, defined by a clover leaf on the lattice. [03 Mar 2016 Y.Namekawa] Add two functions construct_Fmunu_1x1_traceless() and construct_Fmunu_1x2_traceless() to give anti-Hermitian traceless field strength. Add a function construct_Fmunu_plaq_traceless() which defines the anti-Hermitian traceless field strength with an imaginary part of the plaquette. Add five functions contract_2F(), contract_2F_at_t(), contract_2F_at_x(), contract_2F_at_y(), contract_2F_at_z(). Add four functions contract_2F_at_t(), contract_2F_at_x(), contract_2F_at_y(), contract_2F_at_z() to calculate Fourier transformation. Add four functions global_corr_x(), global_corr_y(), global_corr_z(), global_corr_t() which is used in contract_2F_at_?(). [25 May 2017 Y.Taniguchi]
