Detailed Description
Virtual implementation of a pf-FRG numerics core.
The FrgCore represents the central numerics unit for pf-FRG calculations. It defines the interface between the differential equation solver, measurement protocols, and the concrete implementation of flow equations. The FrgCore also defines the interface for reading and writing checkpoints.
Every specific set of flow equations in its different symmetry-constrained form is derived from this class. Custom flow equations are implemented by subclassing the FrgCore and providing implementations of the virtual member functions.
New instances of FrgCore are created by the FrgCoreFactory::newFrgCore() routine.
Constructor & Destructor Documentation
◆ FrgCore()
|
inlineprotected |
Construct a new FrgCore, which takes ownership of the specified measurements.
- See also
- Measurement
- Parameters
-
measurements List of measurement protocols to invoke during the solution of the flow equations.
Member Function Documentation
◆ computeStep()
|
pure virtual |
Virtual implementation of a single RG step in the solution of the flow equations.
The concrete implementation of the method is expected to calculate the flow equation for the current configuration in FrgCore::flowingFunctional and populate FrgCore::flow with the results. It is not expected to make any further modifications.
- See also
- FrgCore::finalizeStep()
Implemented in SU2FrgCore, TRIFrgCore, and XYZFrgCore.
◆ finalizeStep()
|
pure virtual |
Virtual implementation of the finalization of a single RG step in the solution of the flow equations.
The concrete implementation of the method is expected to update the values of FrgCore::flowingFunctional, based on the values of the flow FrgCore::flow and the designated new value of the frequency cutoff.
- Parameters
-
newCutoff New value of the cutoff.
Implemented in SU2FrgCore, TRIFrgCore, and XYZFrgCore.
◆ flow()
|
inline |
Retrieve the vertex flow.
- Returns
- EffectiveAction* Vertex flow.
◆ flowingFunctional()
|
inline |
Retrieve the flowing functional.
- Returns
- EffectiveAction* Flowing functional.
◆ measurements()
|
inline |
Retrieve the list of measurements.
- Returns
- std::vector<Measurement *> List of measurements.
