Ab initio nonrelativistic quantum electrodynamics: Bridging quantum chemistry and quantum optics from weak to strong coupling [PDF]
Physical Review A, 2018 By applying the Born-Huang expansion, originally developed for coupled nucleus-electron systems, to the full nucleus-electron-photon Hamiltonian of non-relativistic quantum electrodynamics (QED) in the long-wavelength approximation, we deduce an exact ...

Dual Optical Hyperbolicity of PdCoO2 and PdCrO2 Delafossite Single Crystals
Advanced Functional Materials, EarlyView.In this work, the hyperbolic response of PdCoO₂ and PdCrO₂ delafossites is investigated for the first time. They exhibit dual hyperbolic regimes, one localized around a phonon absorption in the mid‐infrared spectral region, and the other extending into the visible range.

Advanced Functional Materials, EarlyView.This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

On the Emergence of the Coulomb Forces in Quantum Electrodynamics
Advances in High Energy Physics, 2017 A simple transformation of field variables eliminates Coulomb forces from the theory of quantum electrodynamics. This suggests that Coulomb forces may be an emergent phenomenon rather than being fundamental.

Stochastic Electrodynamics: The Closest Classical Approximation to Quantum Theory
Atoms, 2019 Stochastic electrodynamics is the classical electrodynamic theory of interacting point charges which includes random classical radiation with a Lorentz-invariant spectrum whose scale is set by Planck’s constant.

Large N external-field quantum electrodynamics
Journal of High Energy Physics, 2022 We advocate the study of external-field quantum electrodynamics with N charged particle flavors. Our main focus is on the Heisenberg-Euler effective action for this theory in the large N limit which receives contributions from all loop orders.

Interactions Between Active Matters and Endogenous Fields
Advanced Materials, EarlyView.This review synthesizes endogenous field information and computational methods in contexts such as cancer, wounds, and biofilms. It organizes NAMs and AAMs by sensing, transmitting, and executing functions, compares their limitations, and from these contrasts proposes design strategies for next‐generation AAMs, offering perspectives to foster ...
