Revisiting the Carrollian Scalar Field

Understand

We investigate the (conformally coupled) scalar field on a general Carrollian spacetime in arbitrary dimension.

• The analysis discloses electric and magnetic dynamics.
• For both, we provide the energy and the momenta of the field, accompanied by their conservation equations.
• We discuss the conservation and non-conservation properties resulting from the existence of conformal isometries and the associated charges.
