Key Points
To investigate the transport dynamics and current enhancements in triangular triple-quantum-dot systems.
Utilized exact hierarchical equations of motion (HEOM) formalism.
Analyzed the stationary current in relation to Coulomb interaction and quantum interference.
Explored the effects of electrode coupling strength and chiral currents.
Generated a three-dimensional map of transport current based on inter-dot tunneling and Coulomb interaction.
Demonstrated that increasing Coulomb interaction (U) enhances the stationary current, contrary to usual suppression in linear arrays.
Identified energy shifts caused by Coulomb interactions as a key factor in current enhancement.
Presented a detailed three-dimensional representation illustrating the effects of inter-dot tunneling (t) and Coulomb interaction (U) on current magnitude.
