31 August 2019

We study Gaussian wave beam and wave packet types of solutions to the linearized cold plasma system in a toroidal domain (tokamak). Such solutions are constructed with help of Maslov’s complex germ theory (short-wave or semi-classical asymptoti...

19 May 2021

The tomography of a single quantum particle (i.e., a quantum wave packet) in an accelerated frame is studied. We write the Schrödinger equation in a moving reference frame in which acceleration is uniform in space and an arbitrary function of time. T...

Laser Transverse Modes with Ray-Wave Duality: A Review

  • Yung-Fu Chen,
  • Ching-Hsuan Wang,
  • Xin-Liang Zheng and
  • Min-Xiang Hsieh

24 September 2021

We present a systematic overview on laser transverse modes with ray-wave duality. We start from the spectrum of eigenfrequencies in ideal spherical cavities to display the critical role of degeneracy for unifying the Hermite–Gaussian eigenmodes and p...
