Strong Proton‐Phonon Coupling Drives Fast Ion Transport in Perovskites

Advanced Science, Volume 13, Issue 9, 13 February 2026.
Experimental and computational phonon analysis of ABO3‐type proton conductor BaSnO3 shows that substitution on the B‐site with yttrium forms an imaginary phonon mode which is instrumental for the function as proton conductor. This overcompensates the adverse proton trapping effect of the yttrium.

Transport equation with delayed neutrons

Transport Theory and Statistical Physics, 1990
Abstract In nuclear fission reactor, the decay constant of delayed neutron will often determine the time behavior of the neutron population in a subcritical system or supercritical system or in a critical system in which a neutron source or cross section change with time.

Numerical solution of the neutron transport equation

Journal of Nuclear Energy, 1969
Abstract An outline of a procedure for directly solving the singular integral form of the one-speed neutron transport equation is given. The procedure is illustrated by considering the Milne problem and a one-region critical problem. Examples of numerical results obtained for these two problems are presented.

Eigenvalues of the neutron transport equation

Proceedings of the Physical Society, 1965
Results are given of the eigenvalues obtained for the neutron pulsed-source and diffusion-length problems using the gas kernel. Three methods of solution are reported: the diffusion approximation, the spherical harmonic (P3) approximation and the B0 approximation.
