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 …

Quantum tunneling, in which electrons can tunnel through a finite potential barrier while
simultaneously interacting with other matter excitation, is one of the most fascinating …

We study the open relaxation dynamics of an asymmetric dipole that is ultrastrongly coupled
to a single electromagnetic cavity mode. By using a thermalizing master equation for the …

The study of chemical reactions in environments under nonequilibrium conditions has been
of interest recently in a variety of contexts, including current-induced reactions in molecular …

Circuit quantum electrodynamics (cQED) systems represent an important platform to study
light-matter interaction at the nanoscale. However, an all-electrical scheme for photon …

Quantum thermal transport and two-photon statistics serve as two representative
nonequilibrium features in circuit quantum electrodynamics (cQED) systems. Here we …

Light absorption and emission have their origins in fast atomic-scale phenomena. To
characterize these basic steps (eg, in photosynthesis, luminescence, and quantum optics), it …

The search for ever higher frequency information processing has become an area of intense
research activity within the micro, nano, and optoelectronics communities. Compared to …

Nonclassical two-photon statistics and photon squeezing are considered as representative
features of the nonclassicality of light. In this work we investigate two-photon correlation …

We apply our generalized input-output method (GIOM), introduced in the previous paper of
this series, to prototype molecular junction models describing vibrationally coupled electron …
