By working with several specific Poisson-Lie groups arising from Heisenberg
Lie bialgebras and by carrying out their quantizations, a case is made for a
useful but simple method of constructing locally compact quantum groups. The
strategy is to analyze and collect enough information from a Poisson-Lie group,
and using it to carry out a ``cocycle bicrossed product construction''.
Constructions are done using multiplicative unitary operators, obtaining
C*-algebraic, locally compact quantum (semi-)groups.Comment: 26 page
