For promising modern and parallel GC techniques please check MPL or MaPLe with its novel Automatic Management of Parallelism. It won distinguished paper award in POPL 2024 and ACM SIGPLAN dissertation award 2023 by proposing these two main things [1],[2]:
a) Provably efficient parallel garbage collection based on disentanglement
b) Provably efficient automatic granularity control
