Dynamic control of coupling regimes in oscillator systems via tunable open channels
J Wang, J **ao - arxiv preprint arxiv:2411.12217, 2024 - arxiv.org
We explore a system comprising two oscillators that are coupled to an open channel at
distinct locations. The coupling nature can be adjusted to be coherent, dissipative, or a …
