چکیده
Fully polarized nonlinear Breit-Wheeler pair production from a beam of seed photons is investigated in pulsed plane-wave backgrounds. The particle (electron and positron) spin photon polarization are comprehensively described with the theory density matrix. compact expressions for energy spectrum produced particles, depending on initial beam, derived discussed both linearly circularly laser numerical results suggest an appreciable improvement positron yield by orthogonalizing to polarization, generation highly photons. locally monochromatic approximation constant field benchmarked full quantum electrodynamic calculations.

Plane-polarized helicon waves
By suitably adding rightand left-hand circularly polarized helicon waves in a cylinder, it is possible, in principle, to form linearly polarized modes, contrary to the notion that whistler waves must be circularly polarized. The plane-polarized component is accompanied by a left-hand circularly polarized component which vanishes on axis but becomes important at large radii. The field lines of t...
متن کاملThree-dimensional Periodic Fully Nonlinear Potential Waves
An exact numerical scheme for a long-term simulation of three-dimensional potential fully-nonlinear periodic gravity waves is suggested. The scheme is based on a surfacefollowing non-orthogonal curvilinear coordinate system and does not use the technique based on expansion of the velocity potential. The Poisson equation for the velocity potential is solved iteratively. The Fourier transform met...
متن کاملDegenerate weakly nonlinear elastic plane waves
Weakly nonlinear plane waves are considered in hyperelastic crystals. Evolution equations are derived at a quadratically nonlinear level for the amplitudes of quasi-longitudinal and quasi-transverse waves propagating in arbitrary anisotropic media. The form of the equations obtained depends upon the direction of propagation relative to the crystal axes. A single equation is found for all propag...
متن کاملIncreasing vaccine production using pulsed ultrasound waves
Vaccination is a safe and effective approach to prevent deadly diseases. To increase vaccine production, we propose that a mechanical stimulation can enhance protein production. In order to prove this hypothesis, Sf9 insect cells were used to evaluate the increase in the expression of a fusion protein from hepatitis B virus (HBV S1/S2). We discovered that the ultrasound stimulation at a frequen...

We prove that bounded solutions to an overdetermined fully nonlinear free boundary problem in the plane are one dimensional. Our proof relies on maximum principle techniques and convexity arguments.
