Constant-speed straight-line propagation in free space is a basic characteristic of light, and spatiotemporal couplings recently were used to control light propagation. In the method of flying focus, where temporal chirp and longitudinal chromatism were combined, tunable-velocities and even backward-...
The evolution of the combined system of the electron and two photonic states follows the following unitary operators: S1 and S2 for the electron interaction with the two photonic states, and Uφ for free-space propagation. As detailed in Supplementary Note 1.1, the multiplication of these ...
The problem of the exit of a shock wave from an axisymmetric channel and its propagation in a free space occupied by an ideal gas is examined. This problem has been studied earlier in [1], in which the shock wave front was considered planar, as well as in [2], in which the wave fr...
In the original paper, the authors have shown the efficiency of the procedure by reconstructing the density matrix of the PINEM state created with 2ω photons, they also successfully built the Wigner functions of the states after 5 µm and 1.5 mm of free space propagation, to prove the ...
constant G as fundamental constants; that inertia is the resistance to the change in an accelerating particle's relativistic mass, as it responds to an applied force, keeping its mass-to-energy ratio constant; that curved space is a form of mass/energy where gravitational rest mass and ...
Hugging Face space: https://huggingface.co/spaces/BlinkDL/ChatRWKV-gradio You are welcome to join the RWKV discord https://discord.gg/bDSBUMeFpc to build upon it. We have plenty of potential compute (A100 40Gs) now (thanks to Stability and EleutherAI), so if you have interesting ideas...
Free space propagation signal levelIt can be shown that the level of the signal falls as it moves away from the point where it has been radiated.The rate at which it falls is proportional to the inverse of the square of the distance.Signal level=kd2Signal level=kd2 ...
where F is Fourier transform, \(f_x\), \(f_y\) are spatial frequencies, z is propagation distance, and \({{H}_i}\) is the incoherent free-space propagation transfer function. Using the relationship between incoherent and coherent transfer functions, \({{H}_i}\) can be described by...
accelerating fields, while electron 2 almost always experiences decelerating fields. In fact, the existence of periodic acceleration and deceleration in the present case could compress a femtosecond-width electron pulse into a series of attosecond pulses after a distance of free-space propagation30. ...
