- Abstract summary: We propose a general method for constructing scar models by combining simple modules.
We numerically verify the thermalization and non-integrability of this model and demonstrate the dynamical properties of the scar states.
Due to the continuous tunability of the parameters, our model also enables us to investigate the transitions of QMBS from non-integrable to integrable system.

- Abstract: The phenomenon of quantum many-body scars has received widespread attention
both in theoretical and experimental physics in recent years due to its unique
physical properties. In this paper, based on the $su(2)$ algebraic relations,
we propose a general method for constructing scar models by combining simple
modules.This allows us to investigate many-body scar phenomena in high-spin
systems. We numerically verify the thermalization and non-integrability of this
model and demonstrate the dynamical properties of the scar states. We also
provide a theoretical analysis of the properties of these scar states. For
spin-$1$ case, we find that our 1D chain model reduces to the famous PXP
model[C. J. Turner et al. Phys. Rev. B 98, 155134(2018)] under special
parameter condition. In addition, due to the continuous tunability of the
parameters, our model also enables us to investigate the transitions of QMBS
from non-integrable to integrable system.

We have developed a method to simulate quantum spin models with the Dzyaloshinskii-Moriya interaction (DMI) using Rydberg atom quantum simulators.
Our approach involves a two-photon Raman transition and a transformation to the spin-rotating frame.
As a model that can be simulated in our setup but not in solid-state systems, we consider an $S=frac12$ spin chain with a Hamiltonian consisting of Zeeman energy.

We introduce and study several classes of quantum spin models with multi-body interactions that exhibit quantum many-body scars.
For each example, we show that the scar states behave differently from thermal states by comparing their spectral and dynamical properties with those of other states.
We also show that a superposition of the scar states constructed by the second method exhibits perfectly periodic revivals in the dynamics.
