Conservative and radiative dynamics in classical relativistic scattering and bound systems

Physical Review Research, 2022
As recent work continues to demonstrate, the study of relativistic scattering processes leads to valuable insights and computational tools applicable to the relativistic bound-orbit two-body problem.

Transducer Materials Mediated Deep Brain Stimulation in Neurological Disorders

Advanced Functional Materials, EarlyView.
This review discusses advanced transducer materials for improving deep brain stimulation (DBS) in neurological disorders. These materials respond to light, ultrasound, or magnetic fields, enabling precise, less invasive neuromodulation. Their stimulus‐responsive properties enhance neural control and adaptive therapy, paving the way for next‐generation ...

Classical theory of the optical Venn paradox

AIP Advances
The optical Venn paradox is observed on light crossing three successive linear polarizers whose axes are oriented along x and y and at 45° between x and y.

Nonseparability, Classical and Quantum [PDF]

, 2010
This paper examines the implications of the holonomy interpretation of classical electromagnetism. As has been argued by Richard Healey and Gordon Belot, classical electromagnetism on this interpretation evinces a form of nonseparability, something that ...

Abelian BF-Theory and Spherically Symmetric Electromagnetism [PDF]

, 1999
Three different methods to quantize the spherically symmetric sector of electromagnetism are presented: First, it is shown that this sector is equivalent to Abelian BF-theory in four spacetime dimensions with suitable boundary conditions. This theory, in

Nanoplasmonics Reveal Ionic‐Strength‐Driven Hydration of Nanoparticles

Advanced Functional Materials, EarlyView.
Localized surface plasmon resonance (LSPR) of gold nanoparticles (AuNPs) is modulated by ionic‐strength‐dependent hydration shell compression. A predictive model connects shell thickness to non‐radiative damping and spectral shifts over seven orders of magnitude.

Dynamical laws of superenergy in General Relativity

, 2007
The Bel and Bel-Robinson tensors were introduced nearly fifty years ago in an attempt to generalize to gravitation the energy-momentum tensor of electromagnetism.

ON THE RESPONSE OF DETECTORS IN CLASSICAL ELECTROMAGNETIC BACKGROUNDS [PDF]

Modern Physics Letters A, 1999
We study the response of a detector that is coupled nonlinearly to a quantized complex scalar field in different types of classical electromagnetic backgrounds. Assuming that the quantum field is in the vacuum state, we show that, when in inertial motion, the detector responds only when the electromagnetic background produces particles.
