- ``direct``: simpler current deposition algorithm, described in
the section :doc:`../theory/picsar_theory`. Note that this algorithm is not strictly charge-conserving.
+ If ``algo.current_deposition`` is not specified, the default is
+ ``esirkepov`` (unless WarpX is compiled with ``USE_PSATD=TRUE``, in which
+ case the default is ``direct``).

* ``algo.charge_deposition`` (`string`, optional)
The algorithm for the charge density deposition. Available options are:
