Representation dependence of the neutron-proton kinetic energy in adiabatic deuteron stripping
Jin Lei
Deuteron stripping reactions such as (d,p) are a main tool for studying the single-particle structure of nuclei, and they are usually analyzed with the adiabatic distorted-wave app…
Emulation of coupled-channels scattering for strongly deformed nuclei
M. Catacora-Rios, Kyle Beyer, Jin Lei +1
Nucleon scattering off strongly deformed nuclei such as the actinides requires coupled-channels (CC) calculations in which several members of the ground-state rotational band are c…
FUSION: a skill-based research agent for publicly obtainable nuclear-physics codes
Jin Lei
Running an unfamiliar nuclear-physics code is rarely difficult because of the physics alone. One must find and build the program, learn its input conventions, and decide whether a…
High-Dimensional Bayesian Calibration of Expensive Nuclear Models with Differentiable Emulation
Jin Lei
Full Bayesian calibration of expensive nuclear models has been blocked not by the cost of any single solve, but by the absence of exact likelihood gradients in legacy parameter-dep…
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…
Self-consistent spectral framework for inclusive nonelastic breakup: The Trojan-horse method as its sub-Coulomb resonant limit
Jin Lei
At the keV-scale energies of stellar nucleosynthesis, the resonant charged-particle reactions addressed by the Trojan-horse method (THM) proceed through isolated near-threshold res…
Inclusive breakup reactions with non-spectator fragments: Generalization of the IAV sum rules
Jin Lei
The Ichimura-Austern-Vincent (IAV) sum rule formalism for inclusive breakup reactions treats the detected fragment as a spectator by replacing…
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…
