transition_energies{ }

Calling sequence

quantum{ region{ transition_energies{ } } }

Properties

• usage: \(\mathrm{\textcolor{ForestGreen}{optional}}\)

• items: maximum 1

Functionality

Calculate transition energies (energy difference) between two states in certain bands. Use this if you want to calculate transition energies but but do not want to calculate the matrix elements. Note that the matrix elements defined above also include specifiers for transition energies: output_transition_energies  = yes`.

all_k_points

Calling sequence

quantum{ region{ transition_energies{ all_k_points = ... } } }

Properties

• usage: \(\mathrm{\textcolor{ForestGreen}{optional}}\)

• type: choice

• values: yes or no

• default: yes

Functionality

If all_k_points = yes then transition energies are outputted for all simulation k-points used in integration of densities of states.
