Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials
This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

The photochemical acid generation is refined from the first principles of quan-tum electrodynamics. First, we briefly review the formulation of the quantum theory of light based on the quantum electrodynamics framework to establish the probability of ...

Investigation of the fine structure of antihydrogen. [PDF]
At the historic Shelter Island Conference on the Foundations of Quantum Mechanics in 1947, Willis Lamb reported an unexpected feature in the fine structure of atomic hydrogen: a separation of the 2S1/2 and 2P1/2 states1.

Introducing dynamical dephasing into the photon modes of a waveguide causes spontaneous emission to switch from conventional exponential decay to a robust power‐law behavior visible at short times. The power law arises from photon diffusion in a dynamically disordered environment, uncovering a previously unexplored, decoherence‐induced pathway to ...

Quantum Limitation to the Coherent Emission of Accelerated Charges
Accelerated charges emit electromagnetic radiation. According to classical electrodynamics if the charges move along sufficiently close trajectories they emit coherently, i.e., their emitted energy scales quadratically with their number rather than ...

Neural networks can accelerate modeling and inverse design of electromagnetic devices by several orders of magnitude, but usually require large amounts of data to train. This work demonstrates that integrating knowledge about quasinormal modes into the network architecture reduces the required amount of training data significantly, while simultaneously

A Physically-Motivated Quantisation of the Electromagnetic Field on Curved Spacetimes
Recently, Bennett et al. (Eur. J. Phys. 37:014001, 2016) presented a physically-motivated and explicitly gauge-independent scheme for the quantisation of the electromagnetic field in flat Minkowski space.

Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Abstract A new compilation of the complex refractive index of liquid water is presented, spanning temperatures from 240 $240$ (near homogeneous freezing) to 300 $300$ K and wavelengths from 0.034 $0.034$ μm to 10 m. The real part of the refractive index is derived using the Kramers–Kronig relation, where the imaginary part is constrained by ...

Resurgence in the scalar quantum electrodynamics Euler–Heisenberg Lagrangian
We explore the ideas of resurgence and Padé–Borel resummation in the Euler–Heisenberg Lagrangian of scalar quantum electrodynamics, which has remained largely unexamined in these contexts.
