Leading low-temperature correction to the Heisenberg-Euler Lagrangian

Felix Karbstein

In this note, we show that the well-known leading low-temperature correction to the Heisenberg-Euler Lagrangian in a constant electromagnetic field arising at two loops can be effi…

Discrete Cavity Dynamics in Free-Space Brillouin Laser

Jiabao Peng, Longjie Zhang, Zhenxu Bai +2

Highly coherent lasers are central to modern photonics. To date, high-coherence operation has been achieved predominantly in microcavity and fiber-based platforms. More recently, f…

Resonant Excitation of Surface Plasmon for Wakefield Acceleration by Beating GW Lasers on Smooth Cylindrical Surface

Bifeng Lei, Hao Zhang, Alexandre Bonatto +5

We present a theoretical and numerical study of resonant surface-plasmon (SP) excitation driven by the beating of two co-propagating laser pulses on a smooth cylindrical plasma-vac…

Unambiguous Vector Magnetometry with Structured Light in Atomic Vapor

S. Ramakrishna, S. Fritzsche

Absorption profiles of vector light upon interaction with atomic vapor carries distinct signatures of external magnetic field vector. However, this signature becomes ambiguous for…

Simulating vacuum birefringence with a diffractive beam propagation code

Aimé Matheron, Michal Šmíd, Matt Zepf +1

Ninety years after their prediction, quantum vacuum nonlinearities in macroscopic electromagnetic fields still await a direct experimental verification in the laboratory. A particu…
