  The present work aims to investigate an interacting Umami Chaplygin gas in
the background dynamics of a spatially flat Friedmann-Lemaitre-Robertson-Walker
(FLRW) universe when adiabatic particle creation is allowed. Here, the universe
is taken to be an open thermodynamical model where the particle is created
irreversibly and consequently, the creation pressure comes into the
energy-momentum tensor of the material content. The rate at which the particle
created is assumed to have a linear relation with the Hubble parameter and the
created particle is dark matter (pressureless). The Umami Chaplygin gas is
considered dark energy, pressureless dust is taken as dark matter and a
phenomenological interaction term is taken for mathematical simplicity.
Dynamical analysis is performed to obtain an overall evolution of the model we
consider. The autonomous system is obtained by considering dimensionless
variables in terms of cosmological variables. The local stability of the
critical points and the classical stability of the model are also performed at
each critical point. This study explores some cosmologically viable scenarios
when we constrain the model parameters. Some critical points exhibit the
accelerated de Sitter expansion of the universe at both the early phase as well
as the late phase of evolution which is characterized by completely Umami
Chaplygin fluid equation of state. Scaling solutions are also described by some
other critical points showing late-time accelerated attractors in phase space
satisfying present observational data, and solving the coincidence problem. A
unified cosmic evolution is also achieved within this model describing the
evolution of the universe starting from inflation to late time acceleration
connecting through a matter-dominated intermediate phase. Finally, the
non-singular bouncing behavior of the universe is also investigated for this
model numerically.
