论文摘要
在这项工作中，我们为许多电子系统介绍了一组病毒关系，这些电子系统与田间模式相连，由偶极子近似和使用长度量规来描述。当前，由于它与描述腔体中强烈耦合到光子模式的分子系统的相关性以及与自由空间中的化学性质相比，它可能对这种化学性质的修改，因此人们对这种哈密顿量的溶液越来越感兴趣。通过证明与质量重新归化的联系，并提供了一种从量子电动力学密度功能理论框架中获得总能量的确切方法来证明这种病毒关系的相关性。
In this work we present a set of virial relations for many electron systems coupled to field modes, described by the Pauli--Fierz Hamiltonian in dipole approximation and using length gauge. Currently, there is growing interest in solutions of this Hamiltonian due to its relevance for describing molecular systems strongly coupled to photonic modes in cavities, and in the possible modification of chemical properties of such systems compared to the ones in free space. The relevance of such virial relations is demonstrated by showing a connection to mass renormalization and by providing an exact way to obtain total energies from potentials in the framework of Quantum Electrodynamical Density Functional Theory.
