Learning emergent PDEs in a learned emergent space
Felix P. Kemeth, Tom Bertalan, Thomas Thiem +4
We extract data-driven, intrinsic spatial coordinates from observations of the dynamics of large systems of coupled heterogeneous agents. These coordinates then serve as an emergen…
THz radiation by beating Langmuir waves
S. Son, Sung Joon Moon, J. Y. Park
An intense terahertz (THz) radiation generated by the beating of two Langmuir waves, which are excited by the forward Raman scattering, is analyzed theoretically. The radiation ene…
THz radiation by the frequency down-shift of Nd:YAG lasers
S. Son, Sung Joon Moon, J. Y. Park
The interaction between an intense laser and a relativistic dense electron beam propagating in the same direction could down-shift the laser frequency. This process, which can be u…
Overcoming the Child-Langmuir law via the magnetic mirror effect
S. Son, Sung Joon Moon
The maximum current in a vacuum tube prescribed by the classical Child-Langmuir law can be overcome, when the space-charge effect of the induced potential is mitigated by the mirro…
Entropy Maximization and Instability of Uniformly Magnetized Plasma
S. Son, Sung Joon Moon
A regime where a uniformly magnetized plasma could be unstable to a spatial perturbation in the magnetic field is explored. In this regime, a uniformly magnetized state does not ma…
Cyclotron Resonance in Strongly Magnetized Plasmas and Gamma Ray Burst
S. Son, Sung Joon Moon
A plausible scenario for the gamma ray and the hard x-ray burst in a strongly magnetized plasma, based on the collective plasma maser instability, is proposed. The physical paramet…
