  The many-body mobility edge (MBME) in energy, which separates thermal states
from many-body localization (MBL) states, is a critical yet controversial
concept in many-body systems. Here we examine the quasiperiodic $t_1-t_2$ model
that features a mobility edge. With the addition of nearest-neighbor
interactions, we demonstrate the potential existence of a MBME. Then we
investigate the impact of a type of bond dissipation on the many-body system by
calculating the steady-state density matrix and analyzing the transport
behavior, and demonstrate that dissipation can cause the system to
predominantly occupy either the thermal region or the MBL region, irrespective
of the initial state. Finally, we discuss the effects of increasing system
size. Our results indicate that dissipation can induce transitions between
thermal and MBL states, providing a new approach for experimentally determining
the existence of the MBME.
