Query: Zitterbewegung in monolayer silicene in a magnetic field   We study the Zitterbewegung in monolayer silicene under a perpendicular
magnetic field. Using an effective Hamiltonian, we have investigated the
autocorrelation function and the density currents in this material. Moreover,
we have analyzed other types of periodicities of the system (classical and
revival times). Finally, the above results are compared with their counterparts
in two other monolayer materials subject to a magnetic field: graphene and
MoS$_2$
