Coulomb bridge mechanism for peripheral polarization of weakly bound projectiles
Hao Liu, Jin Lei, Zhongzhou Ren
We identify the matrix elements that carry peripheral polarization of weakly bound projectiles through the Feshbach dynamical polarization potential (DPP) within the continuum-disc…
Channel couplings redirect absorbed flux from peripheral loss to fusion in weakly bound nuclear reactions
Hao Liu, Jin Lei, Zhongzhou Ren
In reactions of weakly bound nuclei, the absorption cross section mixes two physically distinct contributions: inner capture associated with compound-nucleus formation, and periphe…
Exact construction and uniqueness of the coupled-channel Green's function
Hao Liu, Jin Lei, Zhongzhou Ren
We present a rigorous construction and uniqueness proof of the matrix Green's function for coupled radial Schrodinger equations with symmetric coupling potentials. The Green's matr…
Assessing continuum channel importance in continuum-discretized coupled-channels via dynamic polarization potential decomposition
Jin Lei, Hao Liu
A recurring question in continuum-discretized coupled-channels calculations is which continuum channels carry the breakup coupling, both to interpret the reaction and to decide whi…
Coherent Absorption Dynamics: The Dual Role of Off-Diagonal Couplings in Weakly Bound Nuclei
Hao Liu, Jin Lei, Zhongzhou Ren
Disentangling reaction mechanisms in weakly bound nuclei remains a long-standing challenge, complicated by the common practice of treating absorption as an incoherent sum of channe…
Exact Treatment of Continuum Couplings in Nuclear Optical Potentials via Feshbach Theory
Hao Liu, Jin Lei, Zhongzhou Ren
We present a full-coupling construction of the Feshbach effective interaction in a converged continuum-discretized coupled-channels (CDCC) calculation. The method retains the compl…
