Characterization of Transverse Instabilities Driven by Electron Cloud
Electron cloud continues to be one of the main limiting factors of the Large Hadron Collider (LHC), the biggest accelerator at CERN. These clouds form in the beam chamber when positively charged particles are passing through and cause unwanted effects in b ...
EPFL2024Physics-Inspired Equivariant Descriptors of Nonbonded Interactions
Michele Ceriotti, Philip Robin Loche, Kevin Kazuki Huguenin-Dumittan
One essential ingredient in many machine learning (ML) based methods for atomistic modeling of materials and molecules is the use of locality. While allowing better system-size scaling, this systematically neglects long-range (LR) effects such as electrost ...
Washington2023Low and high frequency electromagnetic forces: numerical modelling and practical applications
The understanding and manipulation of nanoscale analytes is a central theme in nanotechnology and has been one of the main driving forces behind the development of this field as we know it today. Furthermore, such a technology has the potential to also rev ...
EPFL2022Multipolar expansions for scattering and optical force calculations beyond the long wavelength approximation
Olivier Martin, Karim Achouri, Andrei Kiselev, Marco Riccardi
We review three different approaches for the calculation of electromagnetic multipoles, namely, the Cartesian primitive multipoles, the Cartesian irreducible multipoles, and the spherical multipoles. We identify the latter as the best suited to describe th ...
AMER PHYSICAL SOC2022Extension of Lorentz reciprocity and Poynting theorems for spatially dispersive media with quadrupolar responses
We provide a self-consistent extension of the Lorentz reciprocity theorem and the Poynting theorem for media possessing electric and magnetic dipolar and quadrupolar responses related to electric and magnetic fields and field gradients thus corresponding t ...
AMER PHYSICAL SOC2021Multipolar origin of electromagnetic transverse force resulting from TE/TM wave interference
Olivier Martin, Karim Achouri, Andrei Kiselev
In this paper, we aim at unveiling the underlying physical mechanism for transversal optical forces, appearing due to the simultaneous illumination of a spherical object with two plane waves possessing different polarizations. The appearance of such a tran ...
