Overview

Theoretical analysis defends interaction-based tunnelling duration against turning-point models, indicating quantum transit times depend directly on barrier thickness and internal potential.

Key Points

Defend an interaction-based formulation of quantum tunnelling time against criticisms favoring phase-change turning-point approaches.
Evaluates theoretical frameworks describing the duration a quantum particle spends interacting with a potential barrier during transmission.
Critiques alternative models that calculate transit time based solely on turning-point phase shifts while omitting barrier thickness and internal potential variation.
Confirms that quantum tunnelling interaction time fundamentally depends on barrier thickness and the internal potential landscape.
Rebuts turning-point approximations by demonstrating consistency with widespread theoretical analyses of barrier traversal.
