When molecules are coupled to an optical cavity, new light–matter hybrid states, so-called
polaritons, are formed due to quantum light–matter interactions. With the experimental …

In this review, we present the theoretical foundations and first-principles frameworks to
describe quantum matter within quantum electrodynamics (QED) in the low-energy regime …

Polaritonic chemistry is an interdisciplinary emerging field that presents several challenges
and opportunities in chemistry, physics, and engineering. A systematic review of polaritonic …

The emerging field of strongly coupled light–matter systems has drawn significant attention
in recent years because of the prospect of altering both the physical and chemical properties …

We present the theoretical derivation and numerical implementation of the linear response
equations for relativistic quantum electrodynamical density functional theory (QEDFT). In …

In this work we investigate the effects that multimode photonic environments, eg, optical
cavities, have on the properties of quantum matter. We highlight the importance of the …

Strong light–matter coupling within electromagnetic environments provides a promising path
to modify and control chemical and physical processes. The origin of the enhancement of …

Polaritonic chemistry has garnered increasing attention in recent years due to pioneering
experimental results, which show that site-and bond-selective chemistry at room …

Nonlinear optical processes associated with even-order nonlinear susceptibilities are critical
for both classical and quantum technologies. Inversion symmetry, however, prevents …

The generation and control of entanglement in a quantum mechanical system are critical
elements of nearly all quantum applications. Molecular systems are promising candidates …
