adjectiveumklapp (not comparable)
- not comparablenatural sciencesPertaining to the transformation of a wave vector to another Brillouin zone as a result of a scattering process.
It implies that our model is dual to a doped Mott system in one dimension where umklapp scattering is frozen at zero temperature.
