  We introduce a system of active matter swarmalators composed of elastically
interacting run-and-tumble active disks with an internal phase $\phi_i$. The
disks experience an additional attractive or repulsive force with neighboring
disks depending upon their relative difference in $\phi_i$. In the absence of
the internal phase, the system forms a Motility-Induced Phase Separated (MIPS)
state, but when the swarmalator interactions are present, a wide variety of
other active phases appear depending upon whether the interaction is attractive
or repulsive and whether the particles act to synchronize or anti-synchronize
their internal phase values. These include a gas-free gel regime, arrested
clusters, a labyrinthine state, a regular MIPS state, a frustrated MIPS state
for attractive anti-synchronization, and a superlattice MIPS state for
attractive synchronization.
