  2. Self-phase modulation - Wikipedia

    en.wikipedia.org/wiki/Self-phase_modulation

    A similar analysis can be carried out for any pulse shape, such as the hyperbolic secant-squared (sech 2) pulse profile generated by most ultrashort pulse lasers. If the pulse is of sufficient intensity, the spectral broadening process of SPM can balance with the temporal compression due to anomalous dispersion and reach an equilibrium state.

  3. Scanning probe microscopy - Wikipedia

    en.wikipedia.org/wiki/Scanning_probe_microscopy

    Scanning probe microscopy (SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. SPM was founded in 1981, with the invention of the scanning tunneling microscope , an instrument for imaging surfaces at the atomic level.

    en.wikipedia.org/wiki/FORM_(symbolic...

    FORM has been the essential tool to calculate the higher-order QCD beta function. The mathematical structure of multiple zeta values has been researched with dedicated FORM programs. [2] The software package FormCalc which is widely used in the physics community to calculate Feynman diagrams is built on top of FORM.

    Unlike other exams, the AP Physics C exams also had 5 options that test-takers could choose from rather than the typical 4. This was changed in an announcement made by College Board in the February 2024 regarding changes to their AP Physics courses for the 2024–25 school year onward, which explained that the multiple choice sections would ...

  9. Acoustic wave equation - Wikipedia

    en.wikipedia.org/wiki/Acoustic_wave_equation

    In physics, the acoustic wave equation is a second-order partial differential equation that governs the propagation of acoustic waves through a material medium resp. a standing wavefield. The equation describes the evolution of acoustic pressure p or particle velocity u as a function of position x and time t .
