Towards quantizing null p-branes: light-cone gauge analysis and physical Hilbert space

Year: 2025

Type: article

Abstract: A bstract We study null p -branes, p -branes with a Carrollian p +1-dimensional worldvolume embedded in a generic D -dimensional flat Minkowski target space. This theory has a generalised BMS p +1 gauge symmetry. By fixing the light-cone gauge, the BMS symmetry is partly fixed, leaving p “momentum constraints” alongside p -dimensional area-preserving diffeomorphisms. We quantise the theory in the light-cone gauge via canonical quantisation and construct the physical Hilbert space by imposing the remaining constraints using sandwich conditions: the constraints must vanish when sandwiched between any two physical states. We show that solutions to the sandwich conditions are classified into p + 1 distinct classes, which we completely specify. In addition, we discuss special and interesting case of membranes in four dimensions and examine the physical implications of the quantised null p -brane and its associated physical Hilbert space.
