NB
unsigned integer, read and write
Current version does not suport bosons, i.e. NB must always be 0.
An integer representing the number of Bosons in the basis. For wavefunction psi, index 0 to psi.NF-1 refers to Fermions, index psi.NF to psi.NF+O.NB-1 refers to Bosons. Changing this number changes the wavefunction. If the new number of Bosons is smaller than the old number all modes referring to Bosons larger than NB-1 will be removed from the determinants.
Example
We can define the function: $$ |\psi\rangle = \left(\frac{1}{\sqrt{4}} a^{\dagger}_0 a^{\dagger}_1 + \frac{1}{\sqrt{4}} a^{\dagger}_0 a^{\dagger}_2 + (1+I)\frac{1}{\sqrt{4}} a^{\dagger}_1 a^{\dagger}_2 \right)|0\rangle, $$ changing the number of bosons in the basis from 0 to 2 currently results in an error.
Input
- Example.Quanty
NF=3 NB=0 psi = NewWavefunction(NF, NB, {{"110",sqrt(1/4)},{"101",sqrt(1/4)},{"011",(1+I)*sqrt(1/4)}}) print(psi.NB) psi.NB=2
Result
