Interactions between light and matter play an instrumental role in spectroscopy, sensing,
quantum information processing and lasers. In most of these applications, light is considered …

In recent years significant experimental advances in nano-scale fabrication techniques and
in available light sources have opened the possibility to study a vast set of novel light-matter …

We give a perspective on simulating electronic excitation and dynamics using the real-time
propagation approach to time-dependent density functional theory (RT-TDDFT) in the plane …

We model a collection of N two-level systems (TLSs) coupled to a multimode cavity via
Meyer-Miller-Stock-Thoss (MMST) dynamics, sampling both electronic and photonic zero …

Linearized augmented planewaves combined with local-orbitals (LAPW+ lo) are arguably
the most precise basis set to represent Kohn–Sham states. When employed within real-time …

For certain correlated electron–photon systems we construct the exact density-to-potential
maps, which are the basic ingredients of a density-functional reformulation of coupled matter …

The dynamical description of the radiative decay of an electronically excited state in realistic
many-particle systems is an unresolved challenge. In the present investigation …

A new modeling formalism to compute the time-dependent behavior of combined
electromagnetic (EM) and quantum mechanical (QM) systems is proposed. The method is …

The integrating factor and exponential time differencing methods are implemented and
tested for solving the time-dependent Kohn-Sham equations. Popular time propagation …

Prediction of the equilibrium populations in quantum dynamics simulations of molecules
exposed to black-body radiation has proved challenging for semiclassical treatments, with …
