RMT: R-matrix with time-dependence. Solving the semi-relativistic, time-dependent Schrodinger equation for general, multi-electron atoms and molecules in intense, ultrashort, arbitrarily polarized laser pulses

RMT is a program which solves the time-dependent Schrödinger equation for general, multielectron atoms, ions and molecules interacting with laser light. As such it can be used to model ionization (single-photon, multiphoton and strong-field), recollision (high-harmonic generation, strong-field rescattering) and, more generally, absorption or scattering processes with a full account of the multielectron correlation effects in a time-dependent manner. Calculations can be performed for targets interacting with ultrashort, intense laser pulses of long wavelength and arbitrary polarization. Calculations for atoms can optionally include the Breit–Pauli correction terms for the description of relativistic (in particular, spin–orbit) effects.RMT是一款可求解与激光相互作用的通用多电子原子、离子及分子含时薛定谔方程的程序。借此，该程序可用于建模电离过程（单光子、多光子及强场电离）、再碰撞过程（高次谐波产生、强场再散射），以及更广泛的以含时方式完整考量多电子关联效应的吸收或散射过程。可针对与长波长、任意偏振态的超短强激光脉冲相互作用的靶材开展计算。针对原子的计算还可选择性添加布雷特-泡利（Breit–Pauli）修正项，以描述相对论效应（尤其是自旋-轨道效应）。
