Drag-Controlled Regime Transitions in the Eddy Saturation Mechanism of the Antarctic Circumpolar Current
Takuro Matsuta, Yuki Tanaka, Atsushi Kubokawa
Eddy saturation -- the weak sensitivity of Antarctic Circumpolar Current (ACC) transport to wind stress -- is a fundamental feature of Southern Ocean dynamics, yet the processes th…
A frictional control mechanism of circumpolar transport in barotropic reentrant channel models
Takuro Matsuta, Atsushi Kubokawa, Humio Mitsudera +1
Recent studies have reported that an increase in the bottom drag coefficient can enhance the volume transport of the Antarctic Circumpolar Current. Several mechanisms have been pro…
Revisiting the Frictional Control of the Antarctic Circumpolar Current From the Energy Diagram
Takuro Matsuta, Yuki Tanaka, Atsushi Kubokawa
The transport of the Antarctic Circumpolar Current (ACC) has been shown to increase with friction. Previous studies explained this counter-intuitive relationship called frictional…
Formulation and evaluation of ocean dynamics problems as optimization problems for quantum annealing machines
Takuro Matsuta, Ryo Furue
Recent advancements in quantum computing suggest the potential to revolutionize computational algorithms across various scientific domains including oceanography and atmospheric sc…
Improving the Lieb-Robinson bound for long-range interactions
T. Matsuta, T. Koma, S. Nakamura
We improve the Lieb-Robinson bound for a wide class of quantum many-body systems with long-range interactions decaying by power law. As an application, we show that the group veloc…
