High-order harmonic generation is a nonlinear optical process that enables the creation of light pulses at frequencies much higher than that from a seed laser. The host medium for this interaction is ...

A Vermont research team has cracked a 90-year-old puzzle, creating a quantum version of the damped harmonic oscillator. By reformulating Lamb’s classical model, they showed how atomic vibrations can ...

The optical properties of liquid crystals have been a subject of study for many years now, with previous papers investigating second harmonic generation in ferroelectric smectic liquid crystals being ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Theoreticians report that they found no evidence of any universal topological signatures after performing the first ab initio investigation of high harmonic generation from topological insulators.

When a guitar string is plucked or a playground swing is set in motion, the movement gradually fades away. Physicists call these “damped harmonic oscillators,” and Newton’s laws do a fine job of ...
