Define basis for Bloch band calculations
Bloch states are calculated suming up all relevant states with momenta in range [-lLimit * 4 * pi /trapWavenegth, +lLimit * 4 * pi /trapWavenegth] Note that factor of 4 occurs since potential lattice period is twice the trapWavelength for standing wave.
- Parameters
lLimit (integer) – Optional, defines maximal momentum to be taken for calculation of Bloch States as lLimit * 4 * pi / trapWavenegth . By default set to 35.
