论文摘要
OpenMMF是一个数值库，旨在评估具有离散频谱的量子系统的时间进化运算符，并由谐波耦合的任意组合驱动。时间进化运算符被计算为多频傅里叶膨胀，这是由于表达频域中时间依赖的schrödinger方程而产生的（HO，Chu和Tietz，Ch。Phys。Lett96，464（1983））。该库为研究具有任意频谱组成的系统提供了通用工具，仅受可用的计算资源的限制。 OpenMMF包括构建系统哈密顿量和各种功能的功能，以计算物理量，例如微米运算符以及状态种群的时间/相平均值。该图书馆对具有多色驾驶系统的系统使用了普遍的打扮状态概念。在本文中，我们描述了OpenMMF的设计和功能，提供了其使用的示例，并讨论了其适用性范围。该库以面向对象的样式fortran90编写，其中包括一组C ++和Python的包装器。
OPENMMF is a numerical library designed to evaluate the Time-Evolution Operator of quantum systems with a discrete spectrum, and driven by an arbitrary combination of harmonic couplings. The time-evolution operator is calculated as a multifrequency Fourier expansion, which results from expressing the time-dependent Schrödinger equation in the frequency domain (Ho, Chu and Tietz, Ch. Phys. Lett 96, 464 (1983)). The library provides a generic tool to study systems with arbitrary spectral composition, limited only by the available computational resources. OPENMMF includes functionalities to build dense and sparse matrix representations of the system Hamiltonian and various functions to calculate physical quantities such as the micromotion operator and time/phase average of state populations. The library uses a generalised notion of dressed state for systems with polychromatic driving. In this paper, we describe the design and functionality of OPENMMF, provide examples of its use and discuss its range of applicability. The library is written in object-oriented style Fortran90 and includes a set of wrappers for C++ and Python.
