Member Function Documentation

void TBTK::TimeEvolver::fixParticleNumber ( bool  particleNumberIsFixed )

inline

Fix particle number. If set to true, the number of particles remain the same throughout the calculation.

DiagonalizationSolver * TBTK::TimeEvolver::getDiagonalizationSolver ( )

inline

Get the DiagonalizationSolver, which contains the eigenvectors, energies, etc.

double TBTK::TimeEvolver::getEigenValue ( int  state )

inline

Get eigenvalue.

int TBTK::TimeEvolver::getNumberOfParticles ( )

inline

Get number of particles.

double TBTK::TimeEvolver::getOccupancy ( int  state )

inline

Get occupancy of state.

void TBTK::TimeEvolver::run

(

)

Run calculation. First self-consistently finds the ground state, and then time evolves the state. The callback set by setCallback is called at each iteration of both the self-consistent loop and time stepping loop.

void TBTK::TimeEvolver::setCallback ( bool(*)(TimeEvolver *timeEvolver)  callback )

inline

Set callback used to update the Hamiltonian.

void TBTK::TimeEvolver::setMaxSCIterations ( int  maxIterations )

inline

Set max iterations for the self-consistent loop.

void TBTK::TimeEvolver::setNumberOfParticles ( int  numberOfParticles )

inline

Set number of particles.

Parameters

Number

of occupied particles. If set to a negative number, the number of particles is determined by the Fermi level. For fixed particle number the Fermi level at the first time step sets the number of paticles, for non-fixed particle number the Fermi level determines the number of particles in each time step.

void TBTK::TimeEvolver::setNumTimeSteps ( int  numTimeSteps )

inline

Set number of time steps for time evolution.

void TBTK::TimeEvolver::setTimeStep ( double  dt )

inline

Set length of time step used for time evolution.
