Detailed Description

template<int RANK, typename BASE>
class quantumtrajectory::QuantumTrajectory< RANK, BASE >

Class hosting common code of MCWF_Trajectory and Master.

It contains the structure::QuantumSystemWrapper and a trajectory::Adaptive::readStateMore_v implementation which sets t0_. Because this class has to be inserted in the inheritence chain of both MCWF_Trajectory and Master, the base class of QuantumTrajectory is passed as a template parameter BASE and the constructor uses perfect forwarding semantics.

Template Parameters

RANK	arity of the Hilbert space
BASE	practically either a trajectory::Adaptive (for Master) or a trajectory::Stochastic (for MCWF_Trajectory)

Member Function Documentation

template<int RANK, typename BASE>

template<typename CONSTRUCT >

void quantumtrajectory::QuantumTrajectory< RANK, BASE >::checkDimension ( const CONSTRUCT &  construct ) const

inlineprotected

Check the dimensions of the stored quantum system against construct

Template Parameters

CONSTRUCT

typically either a quantumdata::StateVector (as in MCWF_Trajectory) or a quantumdata::DensityOperator (as in Master)

Definition at line 70 of file QuantumTrajectory.h.

template<int RANK, typename BASE>

double quantumtrajectory::QuantumTrajectory< RANK, BASE >::getT0 ( ) const

inlineprotected

The time instant of the beginning of the current time step.

If the simulated quantum system is derived from structure::Exact, this is a very crucial piece of data, since this is the time instant when the interaction picture and the normal picture coincide.

Hence, careful bookkeeping is necessary to keep this correct through any change of the trajectory state (e.g. state i/o).
