InfoScience, EarlyView.Pseudomagnetic fields make light and sound emulate charged particles in magnetic fields, enabling magnetic‐free signal processing. This Review summarizes their origins, three implementations in two‐dimensional artificial lattices, and applications in energy localization and robust transport, guiding the design of topological integrated devices ...

The concept of vacuum in quantum electrodynamics [PDF]
, 2010 A re-evaluation of the concept of vacuum in quantum electrodynamics is presented, focusing on the vacuum of the quantized electromagnetic field. In contrast to the ‘nothingness’ associated to the idea of classical vacuum, subtle aspects are found in ...

The classical linear oscillator in classical electrodynamics with classical zero-point radiation
Journal of Physics CommunicationsIn this article, we consider a classical charged particle in a one-dimensional classical linear oscillator potential interacting with classical electromagnetic zero-point radiation.

Gyarmati’s Variational Principle of Dissipative Processes
Entropy, 2014 Like in mechanics and electrodynamics, the fundamental laws of the thermodynamics of dissipative processes can be compressed into Gyarmati’s variational principle. This variational principle both in its differential (local) and in integral (global) forms

Reduced compression time is not sufficient for stability in patellar buttons
Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose Patellar resurfacing in total knee arthroplasty requires stable cement fixation of the patellar button. Unlike femoral and tibial components, the patellar button is held under manual compression until cement curing, potentially prolonging operative time.

Discussion Note: Conceptual Problems in Classical Electrodynamics [PDF]
, 2007 I have argued that the standard ways of modeling classical particle-field interactions rely on a set of inconsistent assumptions. This claim has been criticized in (Muller forthcoming).

Non-Relativistic Quantum Electrodynamics and the Coulomb Interaction
PhysicsThis review explores the foundations of non-relativistic quantum electrodynamics (QED) and its application to atoms and molecules. It follows the traditional route of placing classical electrodynamics in an Hamiltonian framework, followed by Dirac’s ...

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers
Laser &Photonics Reviews, EarlyView.Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...

Conclusions Not Yet Drawn from the Unsolved 4/3-Problem—How to Get a Stable Classical Electron
UniverseIt has been known for over 100 years that there is a discrepancy between Maxwell’s electrodynamics and the idea of a classical electron as the “atom” of electricity.

Probability Calculations Within Stochastic Electrodynamics
Frontiers in Physics, 2021 Several stochastic situations in stochastic electrodynamics (SED) are analytically calculated from first principles. These situations include probability density functions, as well as correlation functions at multiple points of time and space, for the ...
